Résumé [+] [-]The cyclodorippoid crabs from the Philippines collected by the PANGLAO 2004-2005 and AURORA 2007 expeditions are reported. Five species of Cyclodorippidae are reported: Corycodus mina x sp. nov., Ketamia depressa (Ihle, 1916), Krangalangia spinosa (Zarenkov, 1970), Tymolus brucei Tavares, 1991, and Xeinostoma sakaii Tavares, 1993. Corycodus minax is the second species of the genus to be recorded from the Philippines and is most similar to C. merweae Tavares, 1993, from South Africa. Krangalangia spinosa is reported for the first time from the Philippines. Sexual dimorphism in the length of the walking legs (pereopods 2 and 3) is reported for Tymolus brucei and may be a general feature of cyclodorippoids. One new species of Cymonomidae, Cymonomus liui sp. nov., is also reported, and is most similar to C. curvirostris Sakai, 1965, from Japan. Crown Copyright 2011 Published by Elsevier GmbH.

Résumé [+] [-]Jengalpheops rufus gen. nov., sp. nov., is described on the basis of several specimens collected on intertidal sand and mud flats of Panglao I., the Philippines. The uniformly reddish shrimps inhabit burrow mounds of the large callianas-sid mudshrimp, Glypturus armatus (A. Milne Edwards, 1870). Jengalpheops is defined mainly by the dorsally exposed eyestalks; the absence of orbital teeth; the short triangular rostrum; the unspecialized and feebly enlarged chelipeds, with comb-like rows of setae on the carpus and without snapping mechanism on the fingers; the 3rd maxilliped with styliform lateral plate; and the presence of strap-like epipods on the 1st to 4th pereiopods. The new genus appears to be relatively basal within the family, and is presumably most closely related to Potamalpheops Powell, 1979 and Stenalpheops Miya, 1997.

Résumé [+] [-]Two new species of the alpheid shrimp genus Leptalpheus Williams, 1965, are described from the tropical western Pacific. Leptalpheus denticulatus, new species, is described on the basis of several specimens collected in Nhatrang Bay, Vietnam (type locality); Panglao, off Bohol, the Philippines; and Yaqara Bay, Viti Levu, Fiji. Leptalpheus dworschaki, new species, is described on the basis of two specimens collected in Panglao. All specimens were collected from burrows of callianassid ghost shrimps, including Glypturus cf. armatus (A. Milne-Edwards, 1870) and Neocallichirus calmani (Nobili, 1904). Both L. denticulatus, new species, and L. dworschaki, new species, are closely related to L pacificus Banner & Banner, 1974, from Hawaii, differing from the latter species in subtle morphological details.

Résumé [+] [-]A new species of the alpheid shrimp genus Salmoneus Holthuis, 1955, probably an obligate associate of ghost shrimp burrows, is described based on material from Oman (type locality: Darsait near Muscat), Iran and the Philippines. Salmoneus durisi sp. nov. is characterised principally by both chelipeds enlarged, robust, with ventral and dorsal margins of chelae carrying long fine setae, and with minor chela fingers armed with a few large teeth on cutting edges. All specimens of Salmoneus durisi sp. nov. were collected either directly from burrows of larger decapod crustaceans with the aid of a suction pump, or by exposing burrows dug under large subtidal rocks. The Iranian specimen was found together with its presumed host, Neocallichirus calmani (Nobili, 1904). Two additional specimens from Indonesia and the Solomon Islands are tentatively assigned to S. cf. durisi sp. nov., awaiting further studies.

Résumé [+] [-]Phanerophthalmus is a genus of Indo-West Pacific sea slugs inhabiting seagrass and coral reefs with up to now seven species currently recognised as valid. The goals of this study are to revise the systematics of Phanerophthalmus, infer its phylogeny and patterns of diversity, as well as study its diet. Morphology was combined with molecular phylogenetics based on two mitochondrial (cytochrome c oxidase subunit I, 16S rRNA) and one nuclear (28S rRNA) genes. Molecular species delimitation methods (ABGD, DISSECT) were employed to aid delimiting species. Diet was assessed by gut content analysis. Seventeen species were recognised, 10 of them new to science (P. albotriangulatum, sp. nov., P. anettae, sp. nov., P. batangas, sp. nov., P. boucheti, sp. nov., P. cerverai, sp. nov., P. lentigines, sp. nov., P. paulayi, sp. nov., P. purpura, sp. nov., P. rudmani, sp. nov., P. tibiricae, sp. nov.). Phanerophthalmus has its highest diversity in the Western Pacific where 13 species occur with a peak in the Coral Triangle (11 species; three only known from here). Diversity decreases towards the Central Pacific with five species and Indian Ocean/Red Sea with four species. Only two species are distributed across the Indo-West Pacific. Preliminary gut content analysis suggests these slugs feed on diatoms.

Résumé [+] [-]With over 1600 extant described species, the Muricidae are one of the most species-rich and morphologically diverse families of molluscs. As predators of molluscs, polychaetes, anthozoans barnacles and other invertebrates, they form an important component of many benthic communities. Traditionally, the classification of muricids at specific and generic levels has been based primarily on shells, while subfamilies have been defined largely by radular morphology, although the composition and relationships of suprageneric groups have never been studied exhaustively. Here we present the phylogenetic relationships of 77 muricid species belonging to nine of the ten currently recognized subfamilies, based on Bayesian inference and Maximum Likelihood analyses of partial sequences of three mitochondrial (12S, 16S and COI) and one nuclear (28S) genes. The resulting topologies are discussed with respect to traditional subfamilial arrangements, and previous anatomical and molecular findings. We confirm monophyly of each of the subfamilies Ergalataxinae, Rapaninae, Coralliophilinae, Haustrinae, Ocenebrinae and Typhinae as previously defined, but earlier concepts of Muricinae, Trophoninae and Muricopsinae are shown to be polyphyletic. Based on our phylogenetic hypothesis, a new arrangement of these subfamilies is proposed.

Résumé [+] [-]The Coralliophilinae are a subfamily of Muricidae, with about 200-250 species, mostly from temperate and tropical oceans, that are associated with anthozoans on which they feed. We present here a phylogenetic hyothesis for the subfamily, based on DNA sequences (650 aligned positions) of the mitochondrial 12S rDNA from 42 coralliophilines and six other muricids, as well as one fasciolariid, which serves as the outgroup. Relationships among the muricid subfamilies were not resolved unequivocally, but coralliophiline monophyly was strongly supported. Two major clades emerged within the Coralliophilinae, both well supported in a Bayesian analysis. The genera Coralliophila and Babelomurex as commonly understood, are clearly polyphyletic and in need of redefinition. Our results indicate multiple, independent incursions of Coralliophilinae into deep water habitats, several producing subsequent radiations.

Résumé [+] [-]A new genus-level classification of the Conoidea is presented, based on the molecular phylogeny of Puillandre et al. in the accompanying paper. Fifteen lineages are recognized and ranked as families to facilitate continuity in the treatment of the names Conidae (for 'cones') and Terebridae in their traditional usage. The hitherto polyphyletic 'Turridae' is now resolved as 13 monophyletic families, in which the 358 currently recognized genera and subgenera are placed, or tentatively allocated: Conorbidae (2 (sub) genera), Borsoniidae (34), Clathurellidae (21), Mitromorphidae (8), Mangeliidae (60), Raphitomidae (71), Cochlespiridae (9), Drilliidae (34), Pseudomelatomidae (=Crassispiridae) (59), Clavatulidae (14), Horaiclavidae new family (28), Turridae s. s. (16) and Strictispiridae (2). A diagnosis with description of the shell and radulae is provided for each of these families.

Résumé [+] [-]The genus Paramunida belongs to the family Munididae, one of the most speciose families among anomuran decapod crustaceans. During the PANGLAO 2004, PANGLAO 2005, and AURORA 2007 expeditions in the Philippines, eight species of the genus were collected, including a new record and three new species, namely Paramunida akaina, P. aspera, and P. aurora. These new lineages are distinguished by subtle and constant morphological differences, which are in agreement with molecular evidence from the mitochondrial markers ND1 and 16S. Here, we describe these new species, provide new distribution records, and present phylogenetic relationships within the genus.

Résumé [+] [-]The Terebridae are a diverse family of tropical and subtropical marine, gastropods that use a complex and modular venom apparatus to produce toxins that capture polychaete and enteropneust preys. The complexity of the terebrid venom apparatus suggests that venom apparatus development in the Terebridae could be linked to the diversification of the group and can be analyzed within a molecular phylogenetic scaffold to better understand terebrid evolution. Presented here is a molecular phylogeny of 89 terebrid species belonging to 12 of the 15 currently accepted genera, based on Bayesian inference and Maximum Likelihood analyses of amplicons of 3 mitochondrial (COI, 165 and 12S) and one nuclear (28S) genes. The evolution of the anatomy of the terebrid venom apparatus was assessed by mapping traits of six related characters: proboscis, venom gland, odontophore, accessory proboscis structure, radula, and salivary glands. A novel result concerning terebrid phylogeny was the discovery of a previously unrecognized lineage, which includes species of Euterebra and Duplicaria. The non-monophyly of most terebrid genera analyzed indicates that the current genus-level classification of the group is plagued with homoplasy and requires further taxonomic investigations. Foregut anatomy in the family Terebridae reveals an inordinate diversity of features that covers the range of variability within the entire superfamily Conoidea, and that hypodermic radulae have likely evolved independently on at least three occasions. These findings illustrate that terebrid venom apparatus evolution is not perfunctory, and involves independent and numerous changes of central features in the foregut anatomy. The multiple emergence of hypodermic marginal radular teeth in terebrids are presumably associated with variable functionalities, suggesting that terebrids have adapted to dietary changes that may have resulted from predator-prey relationships. The anatomical and phylogenetic results presented serve as a starting point to advance investigations about the role of predator-prey interactions in the diversification of the Terebridae and the impact on their peptide toxins, which are promising bioactive compounds for biomedical research and therapeutic drug development.

Résumé [+] [-]Characterizing speciation processes in the sea remains a highly contentious issue because geographic barriers to gene exchange, which are the initial conditions for the allopatric speciation model, are not obvious. Moreover, many benthic marine organisms have long-lived planktonic larvae that allow them to connect distant patches of habitats. We here analyse the pattern of speciation in the gastropod genus Bursa in which all species have long-lived and planktonic-feeding larvae. We use a large taxonomic and ecologic coverage of Bursidae from the Indo-Pacific. We use an integrative approach to taxonomy to give more support to available taxonomic hypotheses. This analysis revealed cryptic lineages and suggest that a taxonomic revision of the family should be performed. A molecular clock calibrated from the fossil record was used to estimate divergence times. We then focus on the three co-existing species living in the deep waters of New Caledonia. Over the wide sampled area, no genetic structure was detected for the three species. We show that among New Caledonia species, Bursa fijiensis and Bursa quirihorai are reciprocally monophyletic. These two species are the two more closely related species in the inferred phylogeny. The present biogeographic ranges of the two species and the estimated time of divergence make the scenario of geographic isolation followed by secondary contact unlikely.

Untangling species identity in gastropods with polymorphic shells in the genus Bolma Risso, 1826 (Mollusca, Vetigastropoda). European Journal of Taxonomy 288: 1-21. DOI:10.5852/ejt.2017.288
Résumé [+] [-]In shelled molluscs, assigning valid species names to independent evolutionary lineages can be a difficult task. Most original descriptions are based on empty shells and the high levels of variation in shape, color and pattern in some groups can make the shell a poor proxy for species-level identification. The deep-sea gastropod turbinid genus Bolma is one such example, where species-level identification based on shell characters alone is challenging. Here, we show that in Bolma both traditional and molecular taxonomic treatments are associated with a number of pitfalls that can lead to biased inferences about species diversity. Challenges derive from the few phylogenetically informative characters of shells, insufficient information provided in original descriptions and sampling artefacts, which at the molecular level in spatially fragmented organisms can blur distinctions between genetically divergent populations and separate species. Based on a comprehensive dataset combining molecular, morphological and distributional data, this study identified several cases of shell-morphological plasticity and convergence. Results also suggest that what was thought to be a set of distinct, range-restricted species corresponds instead to a smaller number of more widespread species. Overall, using an appropriate sampling design, including type localities, allowed us to assign available names to evolutionarily significant units.

Résumé [+] [-]The shallow-water trapeziid and tetraliid crabs, symbionts of corals and other colonial anthozoans, from the Philippines, New Guinea, and Vanuatu are listed. A total of 13 species of Trapeziidae and six species of Tetraliidae (two new records) are listed for the Philippines, 15 Trapeziidae (four new records), six Tetraliidae (three new records) for New Guinea, and 12 Trapeziidae (six new records), four Tetraliidae (three new records) for Vanuatu. The number of species in these locations. when compared with the number in adjacent areas, does not support the view that the Indo-Malayan region or the Indo-Australian Archipelago have served as a centre of diversification for these two families.

Résumé [+] [-]Material from recent expeditions has provided an opportunity to update the revision of the Indo-West Pacific species of the families Palicidae Bouvier, 1898, and Crossotonotidae A. Milne-Edwards, 1873 (Crustacea, Brachyura, Palicoidea). A species of Neopalicus Moosa & Serène, 1981 from the Austral Islands, French Polynesia was found to be new to science. The new species can be separated from the two previously described species of Neopalicus in the morphologies of its rostrum, suborbital borders, and the abdomen and first pleopods of the male. The male of a species previously known only from the female holotype, Paliculus foliatus Castro, 2000 is also described. Six species of Palicidae and three species of Crossotonotidae are recorded for the fi rst time from the Philippines. One species of Palicidae is a new record for the Solomon Islands in the western Pacific, one species each of Palicidae and Crossotonotidae are new records for Vanuatu in the western Pacific, while 10 species of Palicidae are first-time records for Tonga in the southwestern Pacific at the extreme eastern margin of the Indo-Australian Plate.

Résumé [+] [-]The family Euryplacidae Stimpson, 1871, traditionally included in the Goneplacidae MacLeay, 1838, is revised based on the examination of the type material of many of its species as well as unidentified and previously identified material from around the world. The revised family now consists of 31 species (including five that are described as new) belonging to 13 genera (including four that are described as new): Eucrate De Haan, 1835, with eight species, of which one is new; Euryplax Stimpson, 1859, with two species; Frevillea A. Milne-Edwards, 1880, with three species; Henicoplax n. gen., with five species of which three are new; Heteroplax Stimpson, 1858, monotypic; Machaerus Leach, 1818, with two species; Nancyplax Lemaitre, Garcia-Gomez, von Sternberg & Campos, 2001, monotypic; Platyozius Borradaile, 1902, monotypic; Psopheticoides Sakai, 1969, monotypic; Systroplax n. gen., monotypic; Trissoplax n. gen., with two species, of which one is new; Trizocarcinus Rathbun, 1914, with two species; Villoplax n. gen., monotypic; and Xenocrate Ng & Castro, 2007, monotypic. The genus Platyozius and Eucrate formosensis Sakai, 1974, are removed from the synonymy of Eucrate and E. alcocki Serene, in Serene & Lohavanijaya, 1973, respectively. Neotypes are selected for Heteroplax dentata Stimpson, 1858, and Pilumnoplax sulcatifrons Stimpson, 1858, two species described from Hong Kong that have a confusing taxonomic history. A neotype is also selected for Euryplax nitida Stimpson, 1859, described from the Florida Keys. Seven nominal species described by other authors were found to be junior subjective synonyms for other species: Eucrate affinis Haswell, 1882, E. costata Yang & Sun 1979, E. haswelli Campbell 1969, and Pseudorhombila sulcatifrons var. australiensis Miers, 1884, of Trissoplax dentata (Stimpson, 1858); Galene laevimanus (Lucas, in Jacquinot & Lucas, 1853) of Eucrate dorsalis (White, 1849); Heteroplax nagasakiensis Sakai, 1934, of H. transversa Stimpson, 1858; and Pilumnoplax sulcatifrons Stimpson, 1858, of Eucrate crenata (De Haan, 1835). Eight euryplacid genera are exclusively found in the Indo-West Pacific region (except one species introduced in the Mediterranean), one is exclusive to each the Eastern Atlantic and Tropical Eastern Pacific regions, three to the Western Atlantic region, and one genus has both Western Atlantic and Tropical Eastern Pacific species.

Résumé [+] [-]A phylogenetic analysis of all 17 extant species of the clawed lobster genus Metanephrops based on mitochondrial 12S rRNA, 16S rRNA and cytochrome c oxidase 1, and nuclear histone H3 gene sequences supports the morphological groupings of two of the traditional groups of the genus (the binghami and japonicus groups) but refutes monophyly of the other two groups (the arafurensis and thomsoni groups). The results in general support a recent morphology-based cladistic analysis of this genus except that this study suggests M. neptunus to be a basal rather than a derived species as indicated in the morphological analysis. This species is genetically diverse over its geographical range. Moreover, the two color forms of M. thomsoni are genetically distinct, most likely representing different species. The molecular phylogeny and current distribution pattern of the extant species, together with the fossil record. suggest that the genus originated in the Antarctica in the Cretaceous, followed by diversification and dispersal along the continental shelf of different continents as a result of the vicariant events associated with the breakup of the Southern Temperate Gondwana since Late Cretaceous.

Résumé [+] [-]We test the competing predictions of allopatric speciation and of ecological speciation by dietary specialization in Drupa, an Indo-Pacific genus of carnivorous marine gastropods in the family Muricidae. We use a well-resolved molecular phylogeny (reconstructed from one nuclear and two mitochondrial genes) to show the validity of the traditional species D. elegans, D. rubusidaeus, D. clathrata, D. morum and D. speciosa. ` Drupa ricinus' is shown to consist of three species: D. ricinus s. s., D. albolabris and a new species, possibly endemic to Japan. ` Purpura' aperta is transferred to Drupa. Despite potential widespread dispersal and a high degree of range overlap among sister species, range sizes between sister species are highly asymmetric, suggesting that speciation has been predominately peripatric. The exception is the sister pair D. ricinus s. s. and D. albolabris, which have symmetric range sizes and are sympatric over broad Indo-Pacific ranges. Such symmetry and extensive sympatry are contrary to the predictions of the (peripatric) allopatric model of speciation. Nevertheless, contrary to the predictions of an ecological speciation model based upon dietary specialization, broad dietary range appears to be identical between the species. Small differences in microhabitat preferences (or hypothetical dietary specialization at a fine taxonomic scale) may have been significant in the speciation process or, if initial divergence was allopatric, in permitting subsequent sympatry. Broad dietary shifts appear to have accompanied more ancient divergences within the genus Drupa.

Résumé [+] [-]The validity of the muricid subfamily Ergalataxinae has recently been confirmed with molecular data, but its composition and the relationships among its constituent genera remain unclear. In order to investigate this, we use four genes (28S rRNA, 12S rRNA, 16S rRNA and cytochrome c oxidase subunit I) to construct a Bayesian phylogeny of 52 ergalataxine species in 18 genera, representing c. 40 of the currently accepted species and 86 of the genera. This is the most complete phylogeny of this taxonomically confusing subfamily yet produced. Our results indicate the polyphyly of many traditional genera, including Morula, Pascula and Orania. In order to improve the correspondence between classification and phylogeny, we restrict the definition of Morula, resurrect Tenguella and elevate Oppomorus to full genus, but describe no new genera. Several species in this analysis could not be identified and may be new, but we do not describe them. Further molecular and morphological analyses, in the context of this framework, should help to resolve the remaining ambiguities in the classification of this subfamily. The oldest fossil member of the Ergalataxinae known to us is of Early Oligocene age.

Résumé [+] [-]The monophyly of the muricid subfamily Rapaninae has recently been confirmed with molecular techniques, but its composition and the relationships among its constituent genera remain unclear. We use four genes (28S rRNA, 12S rRNA, 16S rRNA and cytochrome c oxidase subunit I, COI) to construct a Bayesian phylogeny of 80 rapanine species (73% of the approximately 109 currently accepted), representing 27 of the 31 nominal genera. This is the most complete phylogeny of this taxonomically confusing subfamily yet produced. We propose a revised phylogenetic classification of the Rapaninae, assigning the recognized species to 28 genera. Most of the morphologically-defined rapanine genera are considered valid, including Purpura, Drupa, Thais and Nassa, but many of them are here restricted or redefined so that they are monophyletic. In particular the familiar genus Thais is narrowly restricted to a single species. Many groups previously accepted as subgenera, including Mancinella, Vasula, Thalessa and Thaisella, are here accorded full generic rank. We describe one new genus, Indothais. While we do not formally alter species-level taxonomy, we show molecular evidence for two cryptic species and several instances of probable species synonymy. We estimate the age of diversification of the Rapaninae as Late Cretaceous (75.9 Ma) and of many of its genera as Miocene. (C) 2012 Elseviei Inc. All rights reserved.

Résumé [+] [-]Five species of the family Stylodactylidae Bate, 1888 and two species of Bathypalaemonellidae de Saint Laurent, 1985, were collected by the PANGLAO 2004 and 2005 expeditions to the Philippines. A member of the Stylodactylidae, Stylodactylus gracilis new species, collected at 2149-2217 m, is described and illustrated. The new species is distinguished from the 15 described species of Stylodactylus by a very thin and glabrous integument; a very long ( 0.8 times of carapace length) antennular peduncle, by the lengthening of the second segment ( 1.8 times longer than first); thin and very long third to fifth pereopods, as a result of the lengthening of the meri and propodi. The two species of Bathypalaemonellidae, Bathypalaemonella aff. hayashii Komai, 1995, and Bathypalaemonetes brevirostris ( Bruce, 1986), represent new records for the Philippines.

Résumé [+] [-]The deep sea of temperate south-eastern Australia appears to be a ‘hotspot’ for diversity and endemism of conoidean neogastropods of the family Raphitomidae. Following a series of expeditions in the region, a considerable amount of relevant DNA-suitable material has become available. A molecular phylogeny based on this material has facilitated the identification of diagnostic morphological characters, allowing the circumscription of monophyletic genera and the introduction of several new genus-level taxa. Both named and new genera are presently being investigated through integrative taxonomy, with the discovery of a significant number of undescribed species. As part of this ongoing investigation, our study focuses on the genera Famelica Bouchet & Warén, 1980, Glaciotomella Criscione, Hallan, Fedosov & Puillandre, 2020 and Rimosodaphnella Cossmann, 1914. We subjected a comprehensive mitochondrial DNA dataset of representative deep-sea raphitomids to the species delimitation methods ABGD and ASAP that recognised 18 and 15 primary species hypotheses (PSHs) respectively. Following additional evaluation of shell and radular features, and examination of geographic and bathymetric ranges, nine of these PSHs were converted to secondary species hypotheses (SSHs). Four SSHs (two in Famelica and two in Rimosodaphnella) were recognised as new, and formal descriptions are provided herein.

Criscione F., Hallan A., Puillandre N. & Fedosov A. 2021. Where the snails have no name: a molecular phylogeny of Raphitomidae (Neogastropoda: Conoidea) uncovers vast unexplored diversity in the deep seas of temperate southern and eastern Australia. Zoological Journal of the Linnean Society 191(4): 961-1000. DOI:10.1093/zoolinnean/zlaa088
Résumé [+] [-]Abstract Although raphitomid snails are a dominant component of gastropod communities in deep seas worldwide, their systematics is still largely tentative. We assembled the most complete sampling of Raphitomidae from south-eastern Australia to date. Based on morphological and molecular data from this material, we produced a robust phylogenetic framework and used it to delimit genera. For the focus area, our results show a large proportion of undescribed species- and genus-level taxa, 11 of which are formally described herein. We demonstrate that the examination of purely morphological characters rarely suffices for the purpose of accurate genus delimitation. As a result, some traditionally highly diverse raphitomid genera (such as Gymnobela) turn out to be artificial assemblages of several unrelated, mostly undescribed, genus-level lineages. Our data suggest that comparable configurations of shell and radular features, observed at the genus level, commonly do not reflect true phylogenetic relationships. However, our results are inconclusive as to whether homoplasy or conservatism are the drivers of this phenomenon. Accommodating for the inevitable sampling biases, south-eastern Australia appears as a possible hotspot for both raphitomid diversity and endemism, when compared with adjacent areas.

Résumé [+] [-]Fissurellidae are marine gastropods with a worldwide distribution and a rich fossil record. We integrate molecular, geographical and fossil data to reconstruct the fissurellid phylogeny, estimate divergence times and investigate historical routes of oceanic dispersal. With five molecular markers for 143 terminals representing 27 genera, we resolve deep nodes and find that many genera (e.g., Emarginula, Diodora, Fissurella) are not monophyletic and need systematic revision. Several genera classified as Emarginulinae are recovered in Zeidorinae. Future work should prioritize emarginuline genera to improve understanding of ancestral traits and the early evolution of fissurellids. Tree calibration with the fossilized birth-death model indicates that crown fissurellids originated around 175 Ma, and generally resulted in younger ages for the earliest nodes than the node dating approach. Model-based biogeographic reconstruction, supported by fossils, infers an Indo-West Pacific origin, with a westward colonization of new oceans via the Tethys Seaway upon the breakup of Pangea. Western Atlantic clades then served as source for dispersal towards other parts of the globe. As the sister group to all other fissurellids, Rimula is ranked in its own subfamily, Rimulinae stat. nov. New synonyms: Hemitominae syn. nov. of Zeidorinae stat. nov.; Cranopsis syn. nov. of Puncturella; Variegemarginula syn. nov. of Montfortula.

Résumé [+] [-]The taxonomy of majid spider crabs collected from recent southwest Indian Ocean cruises belonging to Eurynome Leach, 1814, and allied genera is treated. Eurynome longimana Stimpson, 1857, long synonymised with the European E. aspera (Pennant, 1777), is here recognised as a distinct species. Stimpson’s (1857) species can be distinguished by the armature of granules on the third maxilliped, proportions and armature of the ambulatory merus, relatively shorter ambulatory dactylus, structure of the male sternopleonal cavity and relative proportions of the male first gonopod. The composition of Choniognathus Rathbun, 1932, is discussed and the type species, C. koreensis Rathbun, 1932, is figured. One species, C. verhoeffi (Balss, 1929), is not considered to be a member of Choniognathus and its taxonomy is discussed. A new spinose species, C. spinosus, is also described. Seiitaoides Griffin & Tranter, 1986, is revised, and two new species, S. mirabilis and S. kabuto, are described and compared with S. orientalis (Sakai, 1961) and S. stimpsoni (Miers, 1884). The poorly known Eurynome elegans Stebbing, 1921 is rediscovered, its taxonomy clarified and the species is shown to belong to Kasagia Richer de Forges & Ng, 2007. A second species of Kasagia, K. sudhakari Padate, Manjebrayakath & Ng, 2019, recently described from the Arabian Sea is recorded from southwest Indian Ocean.

Résumé [+] [-]The neogastropod family Columbellidae is a highly successful group of small, primarily epibenthic marine snails distributed worldwide and most abundant in the tropics. The great diversity of the group makes them attractive for studying evolutionary shifts in gastropod anatomy, morphology, ecology and diversity. The existing classification of the family has been based to a large degree on the morphology of the shell and radula. Indeed, membership in the family is traditionally confirmed using the unique morphology of the radula. To reconstruct columbellid phylogeny and assess monophyly of the group, we assembled a multilocus dataset including five mitochondrial and nuclear genes, for 70 species in 31 genera. Phylogenetic analyses using Bayesian inference and maximum likelihood are not well enough resolved to support a subfamilial classification, but do support the monophyly of the family and of several well-defined genera and supra-generic groupings. Two of the most diverse nominal genera, Mitrella and Anachis, are supported as highly polyphyletic. Overall, the resulting topologies indicate that the generic and subfamilial classification is in need of extensive revision but that phylogenomic data are needed to resolve columbellid relationships.

Résumé [+] [-]In most marine gastropods, the duration of the larval phase is a key feature, strongly influencing species distribution and persistence. Antarctic lineages, in agreement with Thorson's rule, generally show a short pelagic developmental phase (or lack it completely), with very few exceptions. Among them is the ascidian-feeding gastropod family Velutinidae, a quite understudied group. Based on a multilocus (COI, 16S, 28S and ITS2) dataset for 182 specimens collected in Antarctica and other regions worldwide, we investigated the actual Antarctic velutinid diversity, inferred their larval development, tested species genetic connectivity and produced a first phylogenetic framework of the family. We identified 15 Antarctic Molecular Operational Taxonomic Units (MOTUs), some of which represented undescribed species, which show two different types of larval shell, indicating different duration of the Pelagic Larval Phase (PLD). Antarctic velutinids stand as an independent lineage, sister to the rest of the family, with extensive hidden diversity likely produced by rapid radiation. Our phylogenetic framework indicates that this Antarctic flock underwent repeated events of pelagic phase shortening, in agreement with Thorson's rule, yielding species with restricted geographic ranges.

Résumé [+] [-]The systematics of several Eastern Atlantic conoidean species, traditionally ascribed to the genus Raphitoma Bellardi, 1847, are revised on the basis of DNA sequence data from three gene regions (cytochrome c oxidase subunit I, 16S rRNA and 12S rRNA). We assign genus ranking to three major lineages (Raphitoma, Cyrillia Kobelt, 1905 and Leufroyia Monterosato, 1884) and suggest that two West African species belong in the subgenus Daphnella (Paradaphne) Laseron, 1954. A new classification, based on molecular systematics and critical study of morphology, is provided for all Eastern Atlantic and Mediterranean species that are currently ascribed to Raphitoma s.l. The genus Clathromangelia Monterosato, 1884 is confirmed as belonging to Raphitomidae. Phylogenetic relationships and genetic distances suggest that Raphitoma maculosa Høisæter, 2016 and R. obesa Høisæter, 2016 may be divergent morphotypes of R. bicolor (Risso, 1826) and Cyrillia aequalis (Jeffreys, 1867), respectively.

High cryptic diversity in the kleptoparasitic genus Hyalorisia Dall, 1889 (Littorinimorpha: Capulidae) with the description of nine new species from the Indo-West Pacific. Journal of Molluscan Studies 86(4): 401-421. DOI:10.1093/mollus/eyaa028
Résumé [+] [-]Species in the family Capulidae (Littorinimorpha: Capuloidea) display a wide range of shell morphologies. Several species are known to live in association with other benthic invertebrates—mostly bivalves and sabellid worms, but also other gastropods—and are believed to be kleptoparasitic filter feeders that take advantage of the water current produced by the host. This peculiar trophic ecology, implying a sedentary lifestyle, has resulted in highly convergent shell forms. This is particularly true for the genus Hyalorisia Dall, 1889, which occurs in deep water in the Caribbean and Indo-West Pacific provinces, with two nominal species recognized so far. Combining morphological, ecological and molecular data, we assessed the diversity of the genus, its phylogenetic position inside the family and its association with its bivalve host, the genus Propeamussium de Gregorio, 1884 (Pectinoidea), resulting in the description of nine new cryptic species. When sympatric, species of Hyalorisia are associated with different host species, but the same species of Propeamussium may be the host of several allopatric species of Hyalorisia.

Fassio G., Russo P., Bonomolo G., Fedosov A.E., Modica M., Nocella E. & Oliverio M. 2022. A molecular framework for the systematics of the Mediterranean spindle-shells (Gastropoda, Neogastropoda, Fasciolariidae, Fusininae). Mediterranean Marine Science 23(3): 623-636. DOI:10.12681/mms.29935
Résumé [+] [-]A remarkably high diversity of native small spindle-shells (Gastropoda, Fasciolariidae, Fusininae) has been recently inventoried in the Mediterranean Sea, with 23 species identified based on shell morphology. They have almost invariably been classified in the genus Fusinus, and a few of them recently moved to other genera (Aptyxis Troschel 1868, Aegeofusinus Russo, 2017 and Gracilipurpura Jousseaume, 1880), mostly based on the sole shell features. We have reconstructed a molecular phylogenetic framework for the Mediterranean Fusininae, focusing on native species representative of the genus-level taxa. Our results confirmed that Fusinus s.s. (type species Murex colus Linnaeus, 1758) should be restricted to a group of large-shelled species from the Indo-West Pacific and does not fit any of the small-shelled Mediterranean fusinines. We confirm that Murex syracusanus Linnaeus, 1758 represents a distinct lineage, and show that for all the remaining species the pattern is suggestive of a single monophyletic radiation of small Mediterranean fusinines, for which the name Pseudofusus Monterosato, 1884 must be used

Neither slugs nor snails: a molecular reappraisal of the gastropod family Velutinidae. Zoological Journal of the Linnean Society: 1-41. DOI:10.1093/zoolinnean/zlac091
Résumé [+] [-]Abstract The systematics of the marine mollusc family Velutinidae has long been neglected by taxonomists, mainly because their often internal and fragile shells offer no morphological characters. Velutinids are usually undersampled owing to their cryptic mantle coloration on the solitary, social or colonial ascidians on which they feed and lay eggs. In this study, we address the worldwide diversity and phylogeny of Velutinidae based on the largest molecular dataset (313 specimens) to date, accounting for > 50% of the currently accepted genera, coupled with morphological and ecological data. Velutinids emerge as a diverse group, encompassing four independent subfamily-level lineages, two of which are newly described herein: Marseniopsinae subfam. nov. and Hainotinae subfam. nov. High diversity was found at genus and species levels, with two newly described genera (Variolipallium gen. nov. and Pacifica gen. nov.) and ≥ 86 species in the assayed dataset, 58 of which are new to science (67%). Velutinidae show a remarkable morphological plasticity in shell morphology, mantle extension and chromatic patterns. This variability is likely to be the result of different selective forces, including habitat, depth and trophic interactions.

Résumé [+] [-]The neogastropod family Costellariidae is a large and successful group of carnivorous marine mollusks that encompasses about 475 living species. Costellariids are most diverse in the tropical Indo-Pacific at a depth interval of 0–200 m, where they are largely represented by numerous species commonly assigned to the genus Vexillum. The present work expands the taxon sampling of a previous phylogeny of the mitriform gastropods to resolve earlier problematic relationships, and thus establish a robust framework of the family, revise its taxonomy, and uncover major trends in the evolution of costellariid morphology. A multicuspidate rachidian is shown to have appeared at least twice in the evolutionary history of the family: it is regarded as an apomorphy of the primarily Indo-Pacific Vexillum–Austromitra–Atlantilux lineage, and has evolved independently in the Nodicostellaria–Mitromica lineage of the western hemisphere. The genera Ceratoxancus and Latiromitra are transferred from the Ptychatractidae to the Costellariidae. Tosapusia, Protoelongata, and Pusia are ranked as full genera, the latter with the three subgenera Pusia, Ebenomitra, and Vexillena. Vexillum (Costellaria) and Zierliana are treated as synonyms of Vexillum. The replacement name Suluspira is proposed for Visaya Poppe, Guillot de Suduiraut & Tagaro, 2006, non Ahyong, 2004 (Crustacea). We introduce four new genera, Alisimitra, Costapex, Turriplicifer, and Orphanopusia, and characterize their anatomy; 14 new species, mostly from deep water in the Indo-Pacific, are described in the genera Tosapusia, Alisimitra, Costapex, and Pusia. At least two species of Costapex gen. nov. have been collected from sunken wood.

Résumé [+] [-]The conoidean family Drilliidae Olsson, 1964 is a species-rich lineage of marine gastropods, showing a high degree of diversification in comparison to other families of Conoidea. Despite intensive molecular phylogenetic studies during the last decade that have led to notable rearrangements of conoidean systematics, the genus- and species-level taxonomy of Drilliidae has not thus far been affected and remains entirely based on shell features. In the current study we revisit species delimitation in a morphological cluster of species from the Indo-Pacific referred to as the Clavus canalicularis complex, using an integrative taxonomy approach. The species in the complex possess robust thick-walled shells typically over 15 mm in height with sculpture of prominent rounded nodules located at the whorl’s shoulder, sometimes sharp and squamiform, or producing long spines. We find that in addition to five known species, the complex comprises four new species. These are described as Clavus brianmayi n. sp. (New Caledonia), Clavus davidgilmouri n. sp. (the Philippines), Clavus andreolbrichi n. sp. (Vanuatu and New Ireland) and Clavus kirkhammetti n. sp. (Madagascar). Clavus exasperatus (Reeve, 1843), which was previously considered widely distributed in IndoPacific, is shown to be confined to the western Indian Ocean.

Résumé [+] [-]With about 800 Recent species, ‘miters’ are a widely distributed group of tropical and subtropical gastropods that are most diverse in the Indo-West Pacific. They include the two families Mitridae and Costellariidae, similar in shell morphology and traditionally treated as close relatives. Some genera of deep-water Ptychatractidae and Volutomitridae are close to miters in shell morphology, and the term ‘mitriform gastropods’ has been introduced to refer to Mitridae, Costellariidae, and this assortment of convergent forms. The present study aimed at the reconstruction of phylogenetic relationships of mitriform gastropods based on representative taxon sampling. Four genetic markers [cytochrome c oxidase subunit I (COI), 16S and 12S rRNA mitochondrial genes, and H3 (Histone 3) nuclear gene] were sequenced for over 90 species in 20 genera, and the molecular data set was supplemented by studies of radula morphology. Our analysis recovered Mitridae as a monophyletic group, whereas the genus Mitra was found to be polyphyletic. Of 42 mitrid species included in the analysis, 37 formed a well-supported ‘core Mitridae’ consisting of four major clades, three of them consistent with the subfamilies Cylindromitrinae, Imbricariinae, and Mitrinae, and Strigatella paupercula standing out by itself. Basal to the ‘core Mitridae’ are four minor lineages, with the genus Charitodoron recognized as sister group to all other Mitridae. The deepwater family Pyramimitridae shows a sister relationship to the Mitridae, with high support for a Pyramimitridae + Mitridae clade. Our results recover the monophyly of the Costellariidae, which form a wellsupported clade that also includes Ptychatractidae, Columbariinae, and Volutomitridae, but not Mitridae. Most derived and diverse amongst Costellariidae are species of Vexillum, characterized by a bow-shaped, multicuspidate rachidian tooth. Several previously unrecognized deep-water costellariid lineages are revealed. Their members retain some plesiomorphies – in particular a tricuspidate rachidian tooth – that makes them morphologically intermediate between ptychatractids and Vexillum. The taxa of Ptychatractidae included in the analysis are not monophyletic, but form three well-supported, unrelated groupings, corresponding respectively to Ceratoxancus + Latiromitra, Exilia, and Exiliodea. None of them shows an affinity to Pseudolividae.

Résumé [+] [-]Alongside confirmation of the monophyly of the gastropod family Mitridae, a recent molecular phylogenetic analysis disclosed multiple inconsistencies with the existing taxonomic framework. In the present study, we expanded the molecular sampling to 103 species, representing 26% of the 402 extant species currently accepted in the family and 16 of the 19 currently accepted extant genera; 83 species were sequenced for four molecular markers [cytochrome c oxidase subunit I (COI), 16S and 12S rRNA, and H3 (Histone 3)]. Molecular analyses were supplemented by morphological studies, focused on characters of the radula and, in a more restricted data set, proboscis anatomy. These data form the basis for a revised classification of the Mitridae. A first dichotomy divides mitrids into two unequal clades, Charitodoron and the Mitridae s.s. Species of Charitodoron show profound differences to all other Mitridae in foregut anatomy (lacking an epiproboscis) and shell morphology (smooth columella, bulbous protoconch of non-planktotrophic type), which leads to the erection of the separate family Charitodoronidae fam. nov. Three traditional subfamilies (Mitrinae, Cylindromitrinae and Imbricariinae) correspond to three of the inferred phylogenetic lineages of Mitridae s.s.; we redefine their contents, reinstate Strigatellinae Troschel, 1869 as valid and establish the new subfamily Isarinae. In the absence of molecular material, a sixth subfamily, Pleioptygmatinae, is included in Mitridae based on morphological considerations only. To resolve the polyphyly of Mitra and Cancilla in their current taxonomic extension, we reinstate the genera Episcomitra Monterosato, 1917, Isara H. & A. Adams, 1853 and Probata Sarasúa, 1989 and establish 11 new genera: Quasimitra, Roseomitra, Fusidomiporta, Profundimitra, Cancillopsis, Pseudonebularia, Gemmulimitra and Neotiara in Mitrinae; Imbricariopsis in Imbricariinae; Carinomitra and Condylomitra are left unassigned to a subfamily. Altogether 32 genera are recognized within the family. Their diversity and distribution are discussed, along with general trends in morphological evolution of the family.

Résumé [+] [-]The conoidean family Terebridae is an intriguing lineage of marine gastropods, which are of considerable interest due to their varied anatomy and complex venoms. Terebrids are abundant, easily recognizable and widely distributed in tropical and subtropical waters, but our findings have demonstrated that their systematics requires revision. Here we elaborate the classification of Terebridae based on a recently published molecular phylogeny of 154 species, plus characters of the shell and anterior alimentary system. The 407 living species of the family, including seven species described herein, are assigned to three subfamilies: Pellifroniinae new subfamily, Pervicaciinae and Terebrinae. The Pellifroniinae comprises five deep-water species in two genera, Pellifronia and Bathyterebra n. gen. Pellifroniinae possess a radula of duplex marginal teeth, well-developed proboscis and venom gland, and a very small rhynchodeal introvert. The Pervicaciinae includes c. 50 species in the predominantly Indo-Pacific genera Duplicaria and Partecosta. Pervicaciinae possess salivary glands, a radula of solid recurved marginal teeth and a weakly developed rhynchodeal introvert, but lack proboscis and venom gland. The remaining Terebridae species are classified into 15 genera in the subfamily Terebrinae (including four genera described herein); nine genera are defined on the basis of phylogenetic data and six solely on shell morphology. The Indo-Pacific genera Profunditerebra n. gen., Maculauger n. gen. and Myurellopsis n. gen. each include about a dozen species. The first is restricted to the deep waters of the Indo-West Pacific, while the latter two range widely in both geographic and bathymetric distribution. Neoterebra n. gen. encompasses about 65 species from a range of localities in the eastern Pacific, Caribbean, and Atlantic, and from varying depths. To characterize the highly diversified genera Terebra, Punctoterebra, Myurella and Duplicaria, each of which comprise several morphological clusters, we propose the use of DNA-based diagnoses. These diagnoses are combined with more informative descriptions to define most of the supraspecific taxa of Terebridae, to provide a comprehensive revision of the group.

Résumé [+] [-]Conoidean gastropods of the genera Kermia, Oliver, and Pseudodaphnella Boettger, (Raphitomidae) are common in shallow-water habitats of the tropical Indo-Pacific. They form a distinct morphologically homogeneous complex, easily recognizable by sculpture and colour pattern, encompassing around 80 described species. Examination of a vast material accumulated during recent expeditions in various regions of the Indo-Pacific revealed a number of undescribed species of this complex. Our material included 32 morphospecies available for molecular phylogenetic study; phylogenetic reconstruction based on the COI gene confirmed the species hypotheses based on morphological characters. A total of 18 terminal taxa were attributed to known species and 14 were identified as new species. Of these, 12 species, for which sufficient material was available, are described. Phylogenetic analysis indicated close relationships of the genera Kermia and Pseudodaphnella with members of some other conoidean genera (specifically Exomilus Hedley, , Paramontana Laseron, and Thetidos Hedley, ) and taxonomic implications of the data obtained are discussed. To test the taxonomic value of protoconch and review its wide use in classification of Conoidea, the evolution of the protoconch morphology was reconstructed using a phylogenetic tree. It has revealed that protoconchs of different types may appear in closely related species, sometimes hardly distinguishable by teleoconch morphology. A switch from planctotrophic to non-planctotrophic mode of development occurred at least four times in the evolutionary history of the Kermia Pseudodaphnella complex, indicating high developmental plasticity of the group. Its role in radiation of the Kermia Pseudodaphnella complex and applications for use of protoconch morphology in the classification of Conoidea are discussed.

Résumé [+] [-]The genus Casmaria H. Adams & A. Adams, 1853 (family Cassidae) is widespread in the tropical Indo-Pacific and has been documented from some Atlantic localities as well. Two Casmaria species, C. erinaceus (Linnaeus, 1758) and C. ponderosa (Gmelin, 1791), are common in Indo-Pacific shallow-water sandy bottom communities and are characterized by high morphological variability; both species encompass multiple, often sympatric forms of uncertain status. In the present study we carry out a phylogenetic analysis of some Philippine Casmaria morphs and demonstrate that one of the distinctive morphs earlier assigned to Casmaria ponderosa is in fact a different species, which we describe as Casmaria boblehmani sp. nov. The smooth form of Casmaria ponderosa, C. ponderosa ponderosa, and the solid nodulose form, widely called “form nodulosa” despite being strikingly different in shell morphology, are shown to be conspecific. Studied specimens of these two morphs even from different localities share the same haplotype of the CO1 gene. In light of these new data on the morphological variability of Casmaria species, we discuss criteria of species delimitation in the genus Casmaria and possible affinities of Casmaria boblehmani sp. nov. within the genus.

Résumé [+] [-]The small conoidean Hemilienardia ocellata is one of the easily recognizable Indo-Pacific “turrids”, primarily because of its remarkable eyespot colour pattern. Morphological and molecular phylogenetic analyses revealed four species that share this “characteristic” colour pattern but demonstrate consistent differences in size and shell proportions. Three new species – Hemilienardia acinonyx sp. nov. from the Philippines, H. lynx sp. nov. from Papua New Guinea and H. pardus sp. nov. from the Society and Loyalty Islands – are described based on the results of phylogenetic analyses. Although the H. ocellata species complex clade falls in a monophyletic Hemilienardia, H. ocellata and H. acinonyx sp. nov. possess a radula with semi-enrolled or notably flattened triangular marginal teeth, a condition that diverges substantially from the standard radular morphology of Hemilienardia and other raphitomids.

Résumé [+] [-]Extracting DNA from gastropods presents particular difficulties due to the capacity of the living animal to retract into the shell, resulting in poor penetration of the ethanol into the tissues. Because the shell is essential to establish the link between sequences and traditional taxonomic identity, cracking the shell to facilitate fixation is not ideal. Several methods are currently in routine use to overcome this difficulty, including chemical relaxation, drilling the shell and boiling. Most of these methods are time-consuming, may be safety hazards and constitute a bottleneck in the preparation of large numbers of specimens in the field. We have experimented with a method traditionally used to clean shells that involves placing the living gastropods in a microwave (MW) oven; the electromagnetic radiation very quickly heats both the animal and the water trapped inside the shell, resulting in separation of the muscles that anchor the animal to the shell. Done properly, the body can be removed intact from the shell and the shell voucher is preserved undamaged. To test the method, the bodies of live-collected specimens from two gastropod species were separated from their shell by microwaving and by anesthetizing/drilling. After identical extraction and PCR procedures, the gels showed no difference in DNA quantity or quality, and the resulting sequences are identical within species. The method was then implemented on a large scale during expeditions, resulting in higher percentage of DNA extraction success. The MWs are also effective for quickly and easily removing other molluscs from their shells, that is, bivalves and scaphopods. Workflows implementing the MW technique show a three- to fivefold increase in productivity compared with other methods.

Résumé [+] [-]Nassariidae are a group of scavenging, predominantly marine, snails that are diversified on soft bottoms as well as on rocky shores, and are the subject of numerous research papers in ecology, ecotoxicology or paleontology. A weak and/or apparently continuous variation in shell characters has resulted in an intimidating taxonomy, with complex synonymy lists. Over 1320 extant nominal species have been described, of which 442 are currently regarded as valid. Above species level, the state of the art is equally hazy, with four subfamilies and twelve genera currently accepted, and many other names in the graveyard of synonymy. A molecular analysis based on three mitochondrial (COI, 16S, 12S) and two nuclear (28S, H3) markers was conducted. Our dataset includes 218 putative nassariid species, comprising 9 of the 12 valid genera, and 25 nominal genera represented by their type species. The monophyly of the Nassariidae as classically construed is not confirmed. Species of Antillophos, Engoniophos, Phos, Nassaria, Tomlinia and Anentome (formerly considered Buccinidae) are included inside the Nassariidae clade. Within the Nassariinae, the tree unexpectedly demonstrates that species from the Atlantic and the Indo-Pacific form different clades which represent several independent diversification events. Through an integrative approach, the reconstruction of ancestral states was addressed for eight characters supposedly informative for taxonomy. Using numerous fossil calibration points, Nassariidae appear to have originated 120 MYA ago in Atlantic temperate waters during the Lower Cretaceous. Our results have a profound impact on nassariid taxonomy, especially with regard to the validity of subfamily- and genus-level names.

Résumé [+] [-]The phylogenetic relationships and evolutionary processes within the subfamily Pontoniinae, a speciose group of shrimps with diverse lifestyles (free living, semi-symbiotic and symbiotic) inhabiting the coral reefs of tropical oceans, are an interesting and undeveloped subject of study. In this work, two mitochondrial ribosomal genes (12S rRNA and 16S rRNA) and two protein-coding nuclear genes (Histone 3 and the sodium–potassium ATPase a-subunit) were employed to reconstruct the phylogenetic relationships of 42 genera and 101 species within Pontoniinae. Compared to previous studies, ten additional genera were shown to be monophyletic groups, and the genera Dactylonia and Periclimenaeus were shown to be paraphyletic. The shallow-water crinoid-associated pontoniines were divided into several groups which were mostly consistent with the morphological analysis. The studied bivalve-associated taxa exhibited ancestries that were traceable to different lineages, and two groups could be distinguished: Anchiopontonia + Conchodytes and Anchistus. The similar situation occurred in other echinoderm-associated pontoniines. These results suggest that pontoniines sharing the same hosts may have different evolutionary origins resulting from multiple intrusions of their hosts by morphologically plastic ancestral groups.

Résumé [+] [-]Thirteen new species of Scissurellidae (Scissurella regalis n. sp., Sinezona mechanica n. sp., Sinezona platyspira n. sp., Sinezona enigmatica n. sp., Sinezona wanganellica n. sp., Satondella azonata n. sp., Satondella bicristata n. sp.), Anatomidae (Anatoma amydra n. sp., Anatoma kopua n. sp., Anatoma megascutula n. sp., Anatoma tangaroa n. sp.), and Larocheidae (Larochea spirata n. sp., Larocheopsis macrostoma n. sp.) are described, all of which occur in New Zealand waters. The greatest geographic source of new taxa is the islands and underwater features off northern New Zealand. The new shell-morphological term "sutsel" is introduced for the area between the SUTure and the SELenizone.

Résumé [+] [-]A survey of the lucinid bivalves of Singapore recorded 18 species, 12 of these located during the Singapore Strait Biodiversity Workshop, two others previously collected from the Straits of Johor and a further four species identified from museum specimens. These are illustrated and briefly described. In 2013 survey, lucinids were uncommon at most locations but a seagrass bed at the southern end of the artificially constructed beach joining Seringat and Lazarus islands, yielded 9 species of lucinids and numerous other infaunal bivalves. By far the most abundant species was the small Pillucina profusa, with fewer numbers of Euanodontia ovum, Cardiolucina macassari, Cavatidens bullula, Leucosphaera philippinensis and Liralucina lyngei. The associated infaunal bivalves included 36 species from 10 families; the most diverse were Tellinidae with 14 species and these are illustrated to assist local identification. Three lucinids, Austriella corrugata, Indoaustriella dalli, and Pegophysema philippiana occurred amongst mangroves in the Strait of Johor. Species for which only museum records are available, such as Codakia paytenorum and Lepidolucina venusta, may be locally extinct. Five Singapore lucinid species were included in a new molecular analysis (18S, 28S and cytochrome b genes) to establish their phylogenetic relationships and anatomical details including, in particular, ctenidial structure and morphology of bacterial symbionts for Eunanodontia ovum and Pillucina profusa.

Molecular phylogenetics and historical biogeography amid shifting continents in the cockles and giant clams (Bivalvia: Cardiidae). Molecular Phylogenetics and Evolution 93: 94-106. DOI:10.1016/j.ympev.2015.07.013
Résumé [+] [-]Reconstructing historical biogeography of the marine realm is complicated by indistinct barriers and, over deeper time scales, a dynamic landscape shaped by plate tectonics. Here we present the most extensive examination of model-based historical biogeography among marine invertebrates to date. We conducted the largest phylogenetic and molecular clock analyses to date for the bivalve family Cardiidae (cockles and giant clams) with three unlinked loci for 110 species representing 37 of the 50 genera. Ancestral ranges were reconstructed using the dispersal–extinction–cladogenesis (DEC) method with a time-stratified paleogeographic model wherein dispersal rates varied with shifting tectonics. Results were compared to previous classifications and the extensive paleontological record. Six of the eight prior subfamily groupings were found to be para- or polyphyletic. Cardiidae originated and subsequently diversified in the tropical Indo-Pacific starting in the Late Triassic. Eastern Atlantic species were mainly derived from the tropical Indo-Mediterranean region via the Tethys Sea. In contrast, the western Atlantic fauna was derived from Indo-Pacific clades. Our phylogenetic results demonstrated greater concordance with geography than did previous phylogenies based on morphology. Time-stratifying the DEC reconstruction improved the fit and was highly consistent with paleo-ocean currents and paleogeography. Lastly, combining molecular phylogenetics with a rich and well-documented fossil record allowed us to test the accuracy and precision of biogeographic range reconstructions.

Résumé [+] [-]Toxoglossate marine gastropods, traditionally assigned to the families Conidae, Terebridae, and Turridae, are one of the most populous animal groups that use venom to capture their prey. These marine animals are generally characterized by a venom apparatus that consists of a muscular venom bulb and a tubular venom gland. The toxoglossan radula, often compared with a hypodermic needle for its use as a conduit to inject toxins into prey, is considered a major anatomical breakthrough that assisted in the successful initial radiation of these animals in the Cretaceous and early Tertiary. The pharmacological success of toxins from cone snails has made this group a star among biochemists and neuroscientists, but very little is known about toxins from the other Toxoglossa, and the phylogeny of these families is largely in doubt. Here we report the first molecular phylogeny for the Terebridae and use the results to infer the evolution of the venom apparatus for this group. Our findings indicate that most of the genera of terebrids are polyphyletic, and one species ("Terebra" (s.l.) jungi) is the sister group to all other terebrids. Molecular analyses combined with mapping of venom apparatus morphology indicate that the Terebridae have lost the venom apparatus at least twice during their evolution. Species in the genera Terebra and Hastula have the typical venom apparatus found in most toxoglossate gastropods, but all other terebrid species do not. For venomous organisms, the dual analysis of molecular phylogeny and toxin function is an instructive combination for unraveling the larger questions of phylogeny and speciation. The results presented here suggest a paradigm shift in the current understanding of terebrid evolution, while presenting a road map for discovering novel terebrid toxins, a largely unexplored resource for biomedical research and potential therapeutic drug development.

Résumé [+] [-]Twenty-four species of Muricidae are reviewed, 15 assigned to Chicomurex Arakawa, 1964 and 9 to Naquetia Jousseaume, 1880, two closely related genera. Each species is listed with the author's name(s), the date of description, the synonymy, the chresonymy, the distribution, the description and some comments; the chresonymy is only cited for misidentified figures in recent publications dealing with Muricidae. Each species is illustrated in colour with many specimens, while scanning electron micrographs are provided for the radulae. Photos of the protoconch are provided for most of the species as well as the spiral cord morphology. The type locality and the type material (holotype only) are noted for each name. In addition, a molecular phylogeny of Chicomurex is reconstructed from eight species using three mitochondrial genes (cytochrome oxidase c subunit I, 12S rRNA, and 16S rRNA). The phylogeny revealed three wellsupported clades within the monophyletic Chicomurex, the grouping of species being congruent with morphology (C. laciniatus complex, C. superbus complex, and C. gloriosus complex). Species sampled includes three recently described species C. lani Houart, Moe & Chen, 2014, C. globus Houart, Moe & Chen, 2015, and C. pseudosuperbus Houart, Moe & Chen, 2015; the specific status of these were assessed and found to be supported by genetic data.

Résumé [+] [-]The superfamily Olivoidea is broadly distributed in the world’s oceans mostly in coastal waters at tropical and subtropical latitudes. It encompasses around 30 Recent genera and 460 species. Two families – Olividae and Olivellidae – are classically recognized within the superfamily. Their shell is very characteristic due to the presence of a modified callused anterior end and a fasciole. Prior to the present work, neither the monophyly of the superfamily nor the relationships among its genera had been tested with molecular phylogenetics. Four genetic markers [cytochrome c oxidase subunit I (COI), 16S and 12S rRNA mitochondrial genes, and Histone 3 (H3) nuclear gene] were sequenced for 42 species in 14 genera. Additionally, 18 species were sequenced for COI only. The molecular dataset was supplemented by anatomical and radula data. Our analysis recovered, albeit with weak support, a monophyletic Olivoidea, which in turn includes with 100% support, in addition to traditional olivoideans, representatives of a paraphyletic Pseudolividae. The relationships between the former families and subfamilies are drastically revised and a new classification of the superfamily is here proposed, now including five families: Bellolividae fam. nov., Benthobiidae fam. nov., Olividae, Pseudolividae and Ancillariidae. Within Olividae four subfamilies are recognized, reflecting the high morphological disparity within the family: Olivinae, Olivellinae, Agaroniinae and Calyptolivinae subfam. nov. All the recent genera are discussed and reclassified based on molecular phylogeny and/or morphology and anatomy. The homology of different features of the shells is established for the first time throughout the superfamily, and a refined terminology is proposed. Based on a correlation between anatomical characteristics and shell features and observations of live animals, we make hypotheses on which part of the mantle is responsible for depositing which callused feature of the shell. Our results demonstrate that morphological data alone should be used with caution for phylogenetic reconstructions. For instance, the radula – that is otherwise considered to be of fundamental importance in the taxonomy of Neogastropoda – is extremely variable within the single family Olividae, with a range of variation larger than within the rest of the entire superfamily. In the refined classification, Pseudolividae are nested within Olivoidea, which is partially returning to ‘the roots’, that is to the classification of Thiele (1929).

Résumé [+] [-]Abstract The superfamily Buccinoidea is distributed across the oceans of the world from the Arctic Ocean to the Antarctic and from intertidal to abyssal depths. It encompasses 3351 recent species in 337 genera. The latest taxonomic account recognized eight full families. For the first time, the monophyly of the superfamily and the relationships among the families are tested with molecular data supplemented by anatomical and radula data. Five genetic markers were used: fragments of mitochondrial COI, 16S rRNA, 12S rRNA and nuclear Histone 3 (H3) and 28S rRNA genes (for 225 species of 117 genera). Our analysis recovered Buccinoidea monophyletic in Bayesian analyses. The relationships between the formerly recognized families and subfamilies are drastically revised and a new classification of the superfamily is here proposed, now including 20 taxa of family rank and 23 subfamilies. Five new families (Chauvetiidae, Dolicholatiridae, Eosiphonidae, Prodotiidae and Retimohniidae) and one subfamily of Nassariidae (Tomliniinae) are described. Austrosiphonidae and Tudiclidae are resurrected from synonymy and employed in a new taxonomical extension. All but 40 recent genera are reclassified. Our results demonstrate that anatomy is rather uniform within the superfamily. With exceptions, the rather uniform radular morphology alone does not allow the allocation of genera to a particular family without additional molecular data.

Résumé [+] [-]The state of the art of turrid (=Turridae s. l.) systematics is that shells- when they include the protoconch - are reliable species-level identifiers, but inadequate proxies for allocation to genera or subfamilies. Generally, the radula is used for allocation to a (sub)family, but the hypothesis that the radula is a more adequate proxy than the shell for relationships has not yet been tested by molecular data. Species of Xenuroturris may have drastically different radulae, with either "'semi-enrolled" or "duplex" marginal teeth, although their shells are very similar or even almost indistinguishable. Molecular data confirm that specimens with different types of radulae constitute different species, but two species of a pair with respectively semi-enrolled and duplex teeth end up being not closely related. However, it is still unresolved whether species with semi-enrolled (=Iotyrris) and duplex teeth (=Xenuroturris) form two supported monophyletic clades. Iotyrris devoizei n.sp. and I. musivum n.sp. are described from Vanuatu, where they occur sympatrically with I. cingulifera and Xenuroturris legitima.

New molecular data have greatly enhanced our understanding of conoidean evolution, allowing the construction of a new family-level classification. This expanding framework has also allowed the discovery of several independent lineages that merit recognition at familial rank. One of these, based on seven specimens collected over more than 20 years from deep waters off New Caledonia, represents a unique, monotypic lineage closely related to Mitromorphidae, which we here name as the new family Bouchetispiridae. This new lineage bears a unique combination of teleoconch, protoconch and anatomical characters previously unknown within the Conoidea, including a translucent, fusiform shell with sculpture of strong axial ribs crossed by spiral cords, a multispiral protoconch of only 2.5 whorls with punctate sculpture, hypodermic marginal teeth and a multilayered venom bulb with two layers of muscle separated by connective tissue. This lineage may represent the sole survivor of a previously more diverse clade, or is simply one of many unique taxa that have arisen among the isolated sea mounts off New Caledonia.

Kantor Y.I. & Puillandre N. 2012. Evolution of the radular apparatus in Conoidea (Gastropoda: Neogastropoda) as inferred from a molecular phylogeny. Malacologia 55(1): 55–90. DOI:10.4002/040.055.0105
Résumé [+] [-]The anatomy and evolution of the radular apparatus in predatory marine gastropods of the superfamily Conoidea is reconstructed on the basis of a molecular phylogeny, based on three mitochondrial genes (COI, 12S and 16S) for 102 species. A unique feeding mechanism involving use of individual marginal radular teeth at the proboscis tip for stabbing and poisoning of prey is here assumed to appear at the earliest stages of evolution of the group. The initial major evolutionary event in Conoidea was the divergence to two main branches. One is characterized by mostly hypodermic marginal teeth and absence of an odontophore, while the other possesses a radula with primarily duplex marginal teeth, a strong subradular membrane and retains a fully functional odontophore. The radular types that have previously been considered most ancestral, “prototypic” for the group (flat marginal teeth; multicuspid lateral teeth of Drilliidae; solid recurved teeth of Pseudomelatoma and Duplicaria), were found to be derived conditions. Solid recurved teeth appeared twice, independently, in Conoidea – in Pseudomelatomidae and Terebridae. The Terebridae, the sister group of Turridae, are characterized by very high radular variability, and the transformation of the marginal radular teeth within this single clade repeats the evolution of the radular apparatus across the entire Conoidea.

Kantor Y.I., Puillandre N., Rivasseau A. & Bouchet P. 2012. Neither a buccinid nor a turrid: a new family of deep-sea snails for Belomitra P. Fischer, 1883 (Mollusca, Neogastropoda) with a review of recent Indo-Pacific species. Zootaxa 3496: 1-64
Résumé [+] [-]The new family Belomitridae is established for the deep-water buccinoid genus Belomitra P. Fischer, 1883, based on morphological (shell and radulae) and molecular evidence. The rachiglossate radula is uniquely characterized by a multicuspid rachidian and lateral teeth with very long narrow bases and two small cusps closer to tip. Molecular analysis of a reduced set of Buccinoidea did not resolve the group as a clade, but shows that Belomitridae forms a well supported clade within Buccinoidea. Species of Belomitra have adult sizes in the 7-53 mm range; they live in deep water, mostly in the 500-2,000 meters range, at low and mid latitudes. Eleven valid species described from the Indo-Pacific were originally named in the families Buccinidae, Columbellidae, Cancellariidae, Volutidae, and Turridae. Fourteen new species are described: Belomitra nesiotica n. sp. (Society Islands to Tonga and Fiji in 580-830 m), B. bouteti n. sp. (Society and Tuamotu Islands in 430-830 m), B. subula n. sp. (Solomon Islands to Vanuatu in 760-1110 m), B. caudata n. sp. (Sulu Sea in 2300 m), B. gymnobela n. sp. (South Pacific, eastern Indonesia and Philippines in 780-2040 m), B. hypsomitra n. sp. (Fiji in 392-407 m), B. brachymitra n. sp. (Fiji in 395-540 m), B. comitas n. sp. (Madagascar and Philippines in 1075-1110 m), B. minutula (Coral Sea in 490 m), B. granulata n. sp. (New Caledonia in 105-860 m), B. reticulata n. sp. (Tonga and Fiji to New Caledonia in 395-656 m), B. decapitata n. sp. (Indian Ocean and New Caledonia in 3680-4400 m), B. admete n. sp. (off Sri Lanka in 2540 m), and B. radula n. sp. (Madagascar in 367-488 m).

Résumé [+] [-]The genus Pseudolatirus Bellardi, 1884, with the Miocene type species Fusus bilineatus Hörnes, 1853, has been used for 13 Miocene to Early Pleistocene fossil species and eight Recent species and has traditionally been placed in the fasciolariid subfamily Peristerniinae Tryon, 1880. Although the fossil species are apparently peristerniines, the Recent species were in their majority suspected to be most closely related to Granulifusus Kuroda & Habe, 1954 in the subfamily Fusininae Wrigley, 1927. Their close affinity was confirmed by the molecular phylogenetic analysis of Couto et al. (2016). In the molecular phylogenetic section we present a more detailed analysis of the relationships of 10 Recent Pseudolatirus-like species, erect two new fusinine genera, Okutanius gen. nov. (type species Fusolatirus kuroseanus Okutani, 1975) and Vermeijius gen. nov. (type species Pseudolatirus pallidus Kuroda & Habe, 1961). Five species are described as new for science, three of them are based on sequenced specimens (Granulifusus annae sp. nov., G. norfolkensis sp. nov., Okutanius ellenae gen. et sp. nov.) and two (G. tatianae sp. nov., G. guidoi sp. nov.) are attributed to Granulifusus on the basis of conchological similarities to sequenced species. New data on radular morphology is presented for examined species.

Résumé [+] [-]The taxonomy of the genus Turris Batsch, 1789, type genus of the family Turridae, widespread in shallow-water habitats of tropic Indo-Pacific, is revised. A total of 31 species of Turris, are here recognized as valid. New species described: Turris chaldaea, Turris clausifossata, Turris guidopoppei, Turris intercancellata, Turris kantori, T. kathiewayae. Homonym renamed: Turris bipartita nom. nov. for Pleurotoma variegata Kiener, 1839 (non Philippi, 1836). New synonymies: Turris ankaramanyensis Bozzetti, 2006 = Turris tanyspira Kilburn, 1975; Turris imperfecti, T. nobilis, T. pulchra and T. tornatum Roding, 1798, and Turris assyria Olivera, Seronay & Fedosov, 2010 = T. babylonia; Turris dollyae Olivera, 2000 = Pleurotoma crispa Lamarck, 1816; Turris totiphyllis Olivera, 2000 = Turris hidalgoi Vera-Pelaez, Vega-Luz & Lozano-Francisco, 2000; Turris kilburni Vera-Pelaez, Vega-Luz & Lozano-Francisco, 2000 = Turris pagasa Olivera, 2000; Turris (Annulaturris) munizi Vera-Pelaez, Vega-Luz & Lozano-Francisco, 2000 = Gemmula lululimi Olivera, 2000. Revised status: Turris intricata Powell, 1964, Pleurotoma variegata Kiener, 1839 (non Philippi, 1836) and Pleurotoma yeddoensis Jousseaume, 1883, are regarded as full species (not subspecies of Turris crispa). Neotype designated: For Pleurotoma garnonsii Reeve, 1843, to distinguish it from Turris garnonsii of recent authors, type locality emended to Zanzibar. New combination: Turris orthopleura Kilburn, 1983, is transferred to genus Makiyamaia, family Clavatulidae.

Résumé [+] [-]Species of the genus Clavus of the conoidean family Drilliidae that occur in the littoral and shallow waters of New Caledonia are here revised. This study is based primarily on recent expedition material from the Institut de Recherche pour le Développement (New Caledonia) and Muséum National d’Histoire Naturelle (France). A total of 22 species is recorded, of which eight are described as new. New species: Clavus boucheti, Clavus delphineae, Clavus virginieae, Clavus picoides, Clavus squamiferus, Clavus devexistriatus, Clavus hylikos, Clavus maestratii; New synonyms: Tylotiella Habe, 1958 = Clavus; Clavus leforestieri Hervier, 1896 = Pleurotoma obliquicostata Reeve, 1845; Pleurotoma mariei Crosse, 1869 = Pleurotoma lamberti Montrouzier, 1860; Clavus mighelsi Kay, 1979, new name for Pleurotoma acuminata Mighels, 1845, non J. Sowerby, 1816, was misidentified by Kay 1979; the lectotype of P. acuminata Mighels, 1845, is mangeliine. Clavus mighelsi sensu Kay 1979, is a synonym of Pleurotoma humilis E. A. Smith, 1879. It is suggested that Pleurotoma pulchella Reeve, 1845, sometimes treated as an Indo-Pacific species, may be a senior synonym of Fenimorea halidorema Schwengel, 1940, from the tropical western Atlantic. Nomen dubium: Pleurotoma mediocris Deshayes, 1863.

Résumé [+] [-]Species of Fragum were collected from shallow waters in the Funafuti Atoll in Tuvalu in 2004, with one species being new. We describe Fragum funafutiense n. sp., which in addition to its occurrence at Funafuti, has now been found in five additional countries in the Indo-West Pacific. It can be differentiated from closely similar species only by consideration of a suite of characters that include shell shape, nature of the umbonal keel, rib number, rib sculpture, constitution of the hinge and nature of the shell window formation. Previously published molecular sequence data, including COI and 16S mtDNA, support this species as distinct from other tested fragines as well. Like all species in the genera Fragum, Corculum, and Lunulicardia, this new species is also photosymbiotic. In contrast to many other cardiids, however, Fragum funafutiense n. sp. exhibits deep penetration of fibrous prismatic microstructure on the posterior shell surface, consistent with window shell microstructure. Window shell microstructure is an adaptation that enhances light penetration through the shell to photosymbionts housed in soft tissue such as mantle, foot, and siphonal tentacles. A lectotype of its congener F. mundum (Reeve, 1845) is herein designated.

Résumé [+] [-]A new species of crangonid shrimp, Philocheras magnioculus, is described on the basis of a single female specimen from off the island of Panglao, southwest of Bohol, the Philippines. The presence of a sharp lateral tooth on the antennal scale links the new species to eight previously described species, but the structure of the rostrum, very large cornea, and poorly sculptured pleon immediately distinguish it from its relatives. The new species is the third Philocheras known from the Philippines.

Résumé [+] [-]Three new species of the pagurid hermit crab genus Catapagurus A. Milne-Edwards, 1880 are described and illustrated on the basis of material from the Bohol Sea, Philippines, collected by the PANGLAO 2004 Marine Biodiversity Project. Catapagurus exilidigitus, new species, appears closest to C. tanimbarensis McLaughlin, 1997 within the C. misakiensis Terao, 1914 species group, but it is readily distinguished from the latter by the wide U-shaped median cleft of the telson. Catapagurus fimbriatus, new species, is notable in having a characteristic fringe of setae on the mesial surfaces of the ambulatory dactyli and propodi of the pereopods 3. Catapagurus latus, new species, appears closest to C. haigae (Asakura, 2001) in the general shape and armature of the ambulatory dactyli within the C. ensifer Henderson, 1888 species group, but might be unique within the group in having a setal cluster on the distoventral portion of each ambulatory propodus. The number of species of Catapagurus known from the Philippines increases to seven.

Résumé [+] [-]The evolutionary relationships of the brachyuran crab superfamily Eriphioidea, commonly known as stone or rubble crabs, are examined. Analysis of three mitochondrial (12S, 16S and COI) and two nuclear loci (18S and Histone 3) was carried out for 51 taxa representing the Carpilioidea, Dairoidea, Eriphioidea, Goneplacoidea, Parthenopoidea, Pilumnoidea, Portunoidea, Pseudozioidea and Xanthoidea. Phylogenetic analyses of molecular data used three methods of inference that recovered similar topologies with minor differences. Maximum parsimony analysis of 20 morphological characters taken from first zoeas of 11 species yielded two equally parsimonious trees and generally supported the molecular analyses. None of the analyses recovered Eriphioidea as monophyletic, and each of the eriphioid families represented by two or more taxa was shown to be polyphyletic in both molecular and larval analyses. This study indicates that the present classification based on adult morphology is incongruent with phylogenetic relationships and that the diagnostic characters the result of convergence (particularly in feeding morphology) rather than shared ancestry.

Zoologischer Anzeiger - A Journal of Comparative Zoology 250(4): 407-448. DOI:10.1016/j.jcz.2011.07.002
Résumé [+] [-]Currently, 13 subfamilies are recognised in the brachyuran family Xanthidae: Actaeinae, Antrocarcininae, Chlorodiellinae, Cymoinae, Etisinae, Euxanthinae, Kraussiinae, Liomerinae, Polydectinae, Speocarcininae, Xanthinae, Zalasiinae and Zosiminae. This classification has been based on shared adult features like a transversely ovate carapace, well defined dorsal carapace regions, usually with lateral dentition, stout chelipeds and relatively short ambulatory legs. Such characters are now considered to be convergent. Consequently a number of higher xanthid taxa may be artifical and not monophyletic. A broad sample of 147 xanthid species representing 75 out of 124 genera from all 13 xanthid subfamilies were sampled in a multi-gene analysis. Four markers (three mitochondria] and one nuclear) were used and yielded a tree with ca. 30 xanthid clades. Monophyletic support was demonstrated for the Antrocarcininae (although substantially redefined), Cymoinae, and Polydectinae. Almost every other subfamily was para- or polyphyletic. Furthermore, the two other families of the Xanthoidea, Pseudorhombilidae and Panopeidae, were found nested within the Xanthidae. The molecular results were consistent with phylogenetic relationships implied by a suite of novel and/or neglected "ventral" adult characters including sternal characters, position of genital openings and morphology of the first zoea, instead of "dorsal" characters traditionally used to infer xanthid relationships.

Résumé [+] [-]For 130 years the diogenid genus Paguropsis Henderson, 1888 was considered monotypic for an unusual species, P. typica Henderson, 1888, described from the Philippines and seldom reported since. Although scantly studied, this species is known to live in striking symbiosis with a colonial sea anemone that the hermit can stretch back and forth like a blanket over its cephalic shield and part of cephalothoracic appendages, and thus the common name “blanket-crab”. During a study of paguroid collections obtained during recent French-sponsored biodiversity campaigns in the Indo-West Pacific, numerous specimens assignable to Paguropsis were encountered. Analysis and comparison with types and other historical specimens deposited in various museums revealed the existence of five undescribed species. Discovery of these new species, together with the observation of anatomical characters previously undocumented or poorly described, including coloration, required a revision of the genus Paguropsis. The name Chlaenopagurus andersoni Alcock & McArdle, 1901, considered by Alcock (1905) a junior synonym of P. typica, proved to be a valid species and is resurrected as P. andersoni (Alcock, 1899). In two of the new species, the shape of the gills, length/width of exopod of maxilliped 3, width and shape of sternite XI (of pereopods 3), and armature of the dactyls and fixed fingers of the chelate pereopods 4, were found to be characters so markedly different from P. typica and other species discovered that a new genus for them, Paguropsina gen. n., is justified. As result, the genus Paguropsis is found to contain five species: P. typica, P. andersoni, P. confusa sp. n., P. gigas sp. n., and P. lacinia sp. n. Herein, Paguropsina gen. n., is proposed and diagnosed for two new species, P. pistillata gen. et sp. n., and P. inermis gen. et sp. n.; Paguropsis is redefined, P. typica and its previously believed junior synonym, P. andersoni, are redescribed. All species are illustrated, and color photographs provided. Also included are a summary of the biogeography of the two genera and all species; remarks on the significance of the unusual morphology; and remarks on knowledge of the symbiotic anemones used by the species. To complement the morphological descriptions and assist in future population and phylogenetic investigations, molecular data for mitochondrial COI barcode region and partial sequences of 12S and 16S rRNA are reported. A preliminary phylogenetic analysis using molecular data distinctly shows support for the separation of the species into two clades, one with all five species of Paguropsis, and another with the two species Paguropsina gen. n.

Macpherson E. & Baba K. 2010. Revision of the genus Sadayoshia (Anomura, Galatheidae), with description of four new species, Studies on Malacostraca 14. Studies on Malacostraca:415-452
Résumé [+] [-]A revision of the genus Sadayoshia Baba, 1969 (type species: S. miyakei Baba, 1969) is carried out based on more than 460 specimens from numerous localities in the Indo-Pacific, revealing the existence of seven species. Sadayoshia edwardsii (Miers, 1884) is redescribed using material collected near the type locality (SW Indian Ocean) and from numerous localities from the Indian and Pacific Oceans. The three previously described species (S. acroporae, S. balica, and S. miyakei) proved to be valid species. Four additional species are described here as new to science: S. latisternata n. sp. from French Polynesia, Loyalty Islands and Mauritius Island; S. lipkei n. sp. from French Polynesia, Solomon Islands, Vanuatu, New Caledonia, Loyalty Islands and Chesterfield Islands; S. inermis n. sp. from Solomon Islands, Vanuatu and New Caledonia; and S. tenuirostris n. sp. from Japan, South China Sea, Palau Islands, Philippines, Indonesia, Solomon Islands, Vanuatu and New Caledonia.

Résumé [+] [-]The genus Galathea is one of the most speciose and unwieldy groups in the family Galatheidae. The examination of more than 9000 specimens of 144 species collected in the Indian and Pacific Oceans using morphological and molecular characters, has revealed the existence of 92 new species. The specimens examined during this study were obtained by various French expeditions supplemented by other collections from various sources, and including the type specimens of some previously described species. Most of the new species are distinguished by subtle but constant morphological differences, which are in agreement with molecular divergences of the mitochondrial markers COI and/or 16S rRNA. Here, we describe and illustrate the new species and redescribe some previously described species for which earlier accounts are not sufficiently detailed for modern standards. Furthermore we include a dichotomous identification key to all species in the genus from the Indian and Pacific Oceans.

Résumé [+] [-]A new species of Calcinus is described from western Pacific material, including specimens previously identified as Calcinus anani Poupin & McLaughlin, 1998. The new species C. fuscus n. sp. differs from C. anani in the colouration in life, and their specific distinction is genetically supported by the barcoding gene cytochrome oxidase I (COI). The two species also have different geographic distributions, with C. fuscus n. sp. ranging from Japan to the Philippines, Papua New Guinea, and New Caledonia, while C. anani is restricted to French Polynesia. Moreover C. fuscus n. sp. is found at shallower depths than its sister species C. anani.

Zootaxa 3835(3): 301-324. DOI:10.11646/zootaxa.3835.3.1
Résumé [+] [-]The new pontoniine shrimp genus, Echinopericlimenes gen. nov., is suggested for four species, Periclimenes hertwigi Balss, 1913, Periclimenes dentidactylus Bruce, 1984, Periclimenes calcaratus Chace & Bruce, 1993 and Echinopericlimenes aurorae sp. nov., belonging to so-called “Periclimenes hertwigi Balss, 1913” species group sensu stricto. The new genus can be clearly separated by the unique form of hepatic tooth greatly extending beyond the pterygostomial margin of carapace, unique form of fingers of pereiopods II (chelipeds) and dactyli of ambulatory pereiopods III–V. All species referring to the new genus are similar in ecology being deep-water dwellers, usually collected deeper that 300 meters in associations with venomous sea urchins of the family Echinothuriidae (Echinodermata: Echinoidea). Remarks on ecology, description of the new species from Philippines and a key to all known species of Echinopericlimenes gen. nov. are presented.

Résumé [+] [-]A new classification is presented based on the results of the recently completed cladistic analysis of the Pylochelidae. The subfamilies Pylochelinae and Pomatochelinae are retained, the latter with the genera Pylocheles and Cheiroplatea; however, the subgenera Xylocheles and Bathycheles are elevated to generic rank together with the nominal subgenus Pylocheles. In addition, one new species, B. phenax, is described in Bathycheles and B. profundus is shown to be conspecific with B. integer. The subfamilies Parapylochelinae, Cancellochelinae, Trizochelinae, and Mixtopagurinae are reduced to ranks of tribes and included in the subfamily Trizochelinae. A new genus Forestocheles is proposed in the tribe Trizochelini. Within the genus Trizocheles, subspecific rank for T. spinosus bathamae is deemed unjustified and this taxon is placed in synonymy with the nominal subspecies T spinosus spinosus. The correct identity of Trizocheles balssi is established and the species mistakenly thought to represent that taxon is described as T. hoensonae, new species. Trizocheles gracilis is found to be conspecific with T. boasi and an additional new species, T. mendanai, is added to the genus. The superfamilial ranks of Cheiroplateoidea, Pomatocheloidea, Pylocheloidea, and Cancellocheloidea proposed by Watabe (2007) are rejected, as is Birgusoidea.

Mclay C.L. 2006. Retroplumidae (Crustacea, Decapoda) from the Indo-Malayan archipelago (Indonesia, Philippine) and the Melanesian arc islands (Solomon Islands, Fiji and New Caledonia), and paleogeographical comments, in Richer de forges B. & Justine J.L.(Eds), Tropical Deep-Sea Benthos volume 24 24. Mémoires du Muséum national d'Histoire naturelle 193:375-391, ISBN:2-85653-585-2
Résumé [+] [-]Seven species of retroplumid crabs are recorded from Indonesia, Philippine Islands, Solomon Islands, Fiji Islands and New Caledonia. These include Retropluma denticulata (Solomon Islands), R. notopus (Fiji), R. plumosa (Fiji), R. quadrata (Philippine Islands), R. serenei (Fiji Islands and New Caledonia), R. laurentae n. sp. (Indonesia, Philippine Islands, Solomon Islands and New Caledonia), and Bathypluma forficula (Solomon Islands and New Caledonia). The new material considerably extends the distribution of retroplumid crabs eastwards in the Pacific and also extends the depth range of several species. There are now ten extant species of retroplumids known in two genera: Bathypluma de Saint Laurent, 1989 and Retropluma Gill, 1894. Although larval development is unknown, their small egg size suggests that retroplumids have indirect development. Three fossil genera, containing eight species, are recognized: Costacopluma Collins & Morris, 1975, Retrocypoda Via Boada, 1957 and Loerenthopluma Beschin et al. 1996. Some of the fossils placed in the Retroplumidae probably belong to the Palicidae Bouvier, 1898. An analysis of recently discovered fossil retroplumids shows that this family first appeared in the Proto-Atlantic Ocean during the Late Cretaceous, but became extinct in the Atlantic by the Pliocene. The family is now only found in Indo-West Pacific seas.

Résumé [+] [-]Relatively few studies have been done to define or assess rarity in the marine environment. Published studies have focused on shallow-water and intertidal habitats, and the available information appears to reflect the same pattern observed in terrestrial environments, i.e., that there are many rare species and few common species in any one given area. However, our studies of the abundance of new and/or supposedly rare taxa of decapod crustaceans from the deep, steep slopes of the island of Balicasag, in the central Philippines, have raised questions on how rarity should be defined in marine invertebrates. Examples of such supposedly rare species of crabs and lobsters (Crustacea: Decapoda) are presented here. That these animals come from deep, steep slopes, a relatively under-studied habitat, highlights the major gaps in current knowledge of marine biodiversity that are in part due to the inadequacy of both traditional and high technology sampling methodologies and the limited habitat types that the former can target. Low-technology, artisanal tangle nets have proved to be an optimal capture technique for deep-water decapod crustaceans on deep, steep slopes; many new taxa have been discovered and, in other cases, perceptions of rarity and endemicity have been corrected.

Résumé [+] [-]Examination of the holotype and other specimens of the type species of Garthiella Titgen, 1986, G. aberrans (Rathbun, 1906), reveals that this genus must be excluded from Chlorodiellinae Ng & Holthuis, 2007, due to the absence of the diagnostic morphological features of the subfamily such as spoon-tipped chelae, prominent dactylo-propodal locks on the ambulatory legs, and subdistal teeth on the ambulatory dactyli. Garthiellinae subfam. nov. is therefore established for this genus, as molecular and morphological evidence show that it cannot be classified in any other subfamily of Xanthidae MacLeay, 1838. A new species of Garthiella from the Bohol Sea, central Philippines, is also described. Garthiella sikatuna sp. nov. can be distinguished from G. aberrans by its relatively flatter and less granular carapace, more pronounced and curved anterolateral teeth, longer and more slender pereopods and by the form of the male first gonopods.

Résumé [+] [-]A new species of xanthid crab (Brachyura: Xanthidae) is described from the Bohol Sea in the central Philippines. Xanthias joanneae sp. nov. is most similar in morphology to X. maculatus Sakai, 1961 (type locality: Sagami Bay, Japan), particularly in the presence of distinctive ocelli on the carapace and pereopods. It can be separated from this species by the greater number of ocelli on the dorsal surface of the carapace, wider teeth separated by narrow notches on the carapace anterolateral margin, absence of longitudinal ridges on the external surface of the chelar palm, shorter and stouter ambulatory legs, narrower male anterior thoracic sternum, and stouter G1.

Résumé [+] [-]In this paper, the relationships of Tritonoharpa Dall, 1908, within Neogastropoda are discussed. Tritonoharpa is indeed similar to Colubraria in the morphology of its head-foot, pallial complex, reproductive and excretory systems, in the presence of an extremely long and coiled proboscis, and a very large stomach. However, it differs from Colubraria in the rest of its foregut anatomy, revealing a cancellariid affinity, and a typical nematoglossan radula. The molecular data confirms Beu and Maxwell's placement of Tritonoharpa in the Cancellariidae close to Plesiotriton. It is also suggested that cancellariids may be the sister-group to the rest of neogastropods. Tritonoharpa has a rather large and well developed midgut gland, resembling the gland of Leiblein. As previously studied cancellarioideans have been shown to lack a well differentiated gland of Leiblein, the present study raises some interesting questions about the evolution of the foregut in Neogastropoda. In fact, if this glandular structure were confirmed as a true homologue of the gland of Leiblein, and the cancellarioideans proved to be the sister group to the remaining neogastropods, the possession of the gland should be considered a synapomorphy of the Neogastropoda.

Résumé [+] [-]Cancellariidae, or nutmeg shells, is a family of marine gastropods that feed on the body fluids and the egg cases of marine animals. The 300 or so living species are distributed worldwide, mostly on soft bottoms, from intertidal to depths of about 1000 m. Although they are a key group for the understanding of neogastropod evolution, they are still poorly known in terms of anatomy, ecology and systematics. This paper reports the first mitochondrial multi-gene phylogenetic hypothesis for the group. Data were collected for 50 morphospecies, representative of 22 genera belonging to the three currently recognized subfamilies. Sequences from three genes (12S, 16S and COI) were analyzed with Maximum Likelihood analysis and Bayesian Inference, both as single gene datasets and in two partitioned concatenated alignment. Largely consistent topologies were obtained and discussed with respect to the traditional subfamilial arrangements. The obtained phylogenetic trees were also used to produce Robinson-Foulds supertrees. Our results confirmed the monophyly of the subfamily Plesiotritoninae, while Admetinae and Cancellariinae, as currently conceived, were retrieved as polyphyletic. Based on our findings we propose changes to the systematic arrangement of these subfamilies. At a lower taxonomic rank, our results highlighted the rampant homoplasy of many characters traditionally used to segregate genera, and thus the need of a critical re-evaluation of the contents of many genera (e.g. Nipponaphera, Merica, Sydaphera, Bivetia), the monophyly of which was not recovered.

Résumé [+] [-]Donacidae is a commercially important family of heterodont bivalves and one of the few bivalve lineages that has successfully colonised brackish and fresh waters. However, to date, no phylogenetic hypothesis exists for this widely distributed group. Here we turn to molecular data from the nuclear and mitochondrial genomes and combine these with the extensive fossil record of donacids to propose an evolutionary hypothesis for the family. Our analyses strongly support the monophyly of Donacidae, including Galatea, Iphigenia and ‘Plebidonax’ deltoides, but render Donax paraphyletic. The subgenus Latona is therefore elevated to genus to accommodate a clade of Indo-Pacific species, while retaining Donax for a clade of mostly Atlantic and American Pacific species, and a few Indo-Pacific species. This latter clade is sister group to Galatea + Iphigenia. The diversification of Donacidae seems to be tightly connected to the opening of the North and South Atlantic Oceans in the Cretaceous, and to the closing of the Tethys Ocean during the Oligocene.

Résumé [+] [-]A new family, Vultocinidae, is established for an unusual new genus and new species of crab ( Crustacea: Brachyura: Goneplacoidea) here described from relatively deep waters in the central Philippines and Vanuatu. Although Vultocinus anfractus, new genus, new species, superficially resembles pilumnid genera like Lophoplax and pseudoziid genera like Planopilumnus in its deeply sculptured carapace and leg surfaces, its male abdomen and gonopods appear to affiiliate it with the Goneplacidae sensu lato instead. However, its suite of many unusual characters requires the recognition of a new family for Vultocinus. Comparisons of the Vultocinidae with the Goneplacidae sensu stricto suggests that the subfamily Mathildellinae, presently regarded as a subfamily, should be recognised as a full family; and two other problematic constituent genera, Progeryon and Conleyus, are also referred to their respective families in the Goneplacoidea. The genus Paragalene is also referred to the Progeryonidae. The extent of the sterno- abdominal cavity along the thoracic sternites, structure of the posterior thoracic sternites, position of the press button of the male abdominal locking mechanism and form of the first four male abdominal segment as characters in the taxonomy of the Goneplacoidea is also discussed.

Résumé [+] [-]A new species of Aphanodactylus is described from Panglao Island, the Philippines. This new species can be distinguished from other species of Aphanodactlyus by the characters of the carapace, the form of the ambulatory legs. and the structure of the male first gonopod. The photograph of the holotype of poorly known Pinnixa brevipes H. Milne Edwards, 1853, is compared with species of Aphanodactylus sensu stricto and the allied genus Gandoa Kammerer, 2006. Its distinctly punctate and rectangular carapace suggest that A. brevipes belongs in Gandoa. A lectotype for Pinnixa brevipes is designated.

Zootaxa 3773(1): 1-63. DOI:10.11646/zootaxa.3773.1.1
Résumé [+] [-]The family Acidopsidae Števčić, 2005, is revised; and two subfamilies are recognised. The Acidopsinae Števčić, 2005, is characterised by the coxal male opening, a quadrate basal antennal article and vulvae arranged near the median longitudinal thoracic sternal groove. Three genera are included in the Acidopsinae: Acidops Stimpson, 1871 (with two species), Parapilumnus Kossmann, 1877 (with two species) and Crinitocinus gen. Nov. (monotypic for Pilumnus alcocki Borradaile, 1902). The Raouliinae Števčić, 2005 (= Typhlocarcinodidae Števčić, 2005; Caecopilumnidae Števčić, 2011), is characterised by its coxo-sternal male opening, a short basal antennal article which is distinctly wider than long and vulvae arranged submedially on thoracic sternite 6. Four genera are included in the Raouliinae: Raoulia Ng, 1987 (with five species, three of which are described as new), Caecopilumnus Borradaile, 1902 (with three species of which one is described as new), Typhlocarcinodes Alcock, 1900 (monotypic) and Thecaplax gen. Nov. (for one new species).

Résumé [+] [-]The family Chasmocarcinidae Serène, 1964, is revised based on the examination of the type material of many of its species as well as unidentified and previously identified material from around the world. The revised family now consists of three subfamilies comprising 16 genera (including eight described as new) and 51 species (including 19 described as new). The subfamily Chasmocarciinae Serène, 1964, consists of Amboplax n. gen. with one species; Angustopelta n. gen. with four species, two of which are new; Camatopsis Alcock & Anderson, 1899, with six species, five of which are new; Chasmocarcinops Alcock, 1900, with one species; Chasmocarcinus Rathbun, 1898, with 11 species, one of which is new; Chinommatia n. gen. with five species, two of which are new; Deltopelta n. gen. with one species; Hephthopelta Alcock, 1899, with two species, one of which is new; Microtopsis Komai, Ng & Yamada, 2012, with two species, one of which is new; Notopelta n. gen. with one species; Statommatia n. gen. with five species, two of which are new; and Tenagopelta n. gen. with three species, two of which are new. The subfamily Megaesthesiinae Števčić, 2005, consists of Alainthesius n. gen. with two species, both of which are new; Megaesthesius Rathbun, 1909, with four species, one of which is new. The subfamily Trogloplacinae Guinot, 1986, consists of Australocarcinus Davie, 1988, with three species, and Trogloplax Guinot, 1986, with one species. A neotype is selected for Chasmocarcinus cylindricus Rathbun, 1901. Three nominal species were found to be junior subjective synonyms of other species: Chasmocarcinus panamensis Serène, 1964, of C. longipes Garth, 1940; Chasmocarcinus rathbuni Bouvier, 1917, of C. typicus Rathbun, 1898; and Hephthopelta superba Boone, 1927, of Deltopelta obliqua (Rathbun, 1898). Thirteen chasmocarcinid genera are exclusively found in the Indo-West Pacific region, one (Chasmocarcinus) in both the Western Atlantic and Tropical Eastern Pacific regions, and two (Deltopelta n. gen. and Amboplax n. gen.) exclusively in the Western Atlantic. Chasmocarcinids are remarkable for occurring from depths exceeding 1000 m to shallow water and completely freshwater habitats: chasmocarcinines and megaesthesiines are found from shallow to deep water marine ecosystems, whereas trogloplacines live in freshwater streams, including cave systems.

Oliverio M. & Modica M.V. 2010. Relationships of the haematophagous marine snail Colubraria (Rachiglossa: Colubrariidae), within the neogastropod phylogenetic framework. Zoological Journal of the Linnean Society 158(4): 779-800. DOI:10.1111/j.1096-3642.2009.00568.x
Résumé [+] [-]The gastropod genus Colubraria includes marine shallow-water species from tropical, subtropical, and temperate rocky coral environments. At least six species are known to feed on fish blood. Although there is general consensus in placing Colubraria in the Neogastropoda, the actual relationships and the systematic position of Colubraria and related genera are unknown. This is partly the consequence of the lack of a clear phylogenetic framework for the Neogastropoda. This study attempts to propose a phylogenetic framework for the Neogastropoda, by testing: (1) a preliminary phylogenetic arrangement for a large number of recognized neogastropod families; (2) the position of Colubraria within the neogastropods; and (3) the relationships of Colubraria within one of the major neogastropod lineages. We used two different molecular data sets. The first set included representatives of at least 14 neogastropod families, for points (1) and (2), and was based on mitochondrial (16S, 12S, and cytochrome oxidase subunit I, COI) and nuclear (28S) DNA sequences, giving a total of 3443 aligned positions. The second data set, for point (3), included 30 buccinoid sequences from mitochondrial 16S, giving a total of 1029 aligned positions. We also studied the anatomy of the type species of Colubraria and compared it with other neogastropods within the new phylogenetic framework. The results included the first phylogeny of the neogastropod based on 50% of the recognized families. This clearly indicated that the nematoglossan Cancellariidae represent a basal offshoot of the monophyletic Neogastropoda, and that the toxoglossan Conoidea are the sister group to the Rachiglossa. Within the Rachiglossa, a colubrariid clade, worthy of family ranking, showed clear buccinoid affinities. Most of the anatomy of Colubraria is congruent with a buccinoid model. The peculiar anatomical features that do not conform to the buccinoid model seem to be related to the evolution of haematophagous feeding.

Résumé [+] [-]A new species of porcelain crab, Polyonyx angustus n. sp., is described on the basis of material collected from Panglao Island, the Central Philippines. It is morphologically allied to P. boucheti Osawa, 2007, P. pilosibrachium Osawa, Naruse & Ng, 2018, and P. utinomii Miyake, 1943, but distinguished by the shape of the carapace and rostrum. Re-examination of the specimens from the Maldives previously referred to P. utinomii has showed that they belong to the new species instead. The present knowledge suggests that P. utinomii is distributed only in the Japanese main islands from central Honshu to Kyushu.

Résumé [+] [-]The genus Bakawan includes species of haminoeid snails associated with mangrove habitats and mud flats in the Indo-West Pacific. Here, we revise the diversity and systematics of the genus Bakawan based on our recent molecular phylogeny (Oskars & Malaquias, 2019) and detailed analysis of morphological characters. We examined a range of morphological characters (the shells, external morphology of the animal, jaw, radula, gizzard plate and male reproductive system) using light and scanning electron microscopy. We also carried out a species delimitation analysis (we used the automatic barcode gap discovery method) based on cytochrome c oxidase subunit I DNA sequence data. Four distinct species were recognized: Bakawan rotundata (A. Adams, 1850), which is the type species of the genus and ranges from the eastern Indian Ocean to the western Pacific; B. fusca (A. Adams, 1850), currently known only from the Philippines; and two species new to science, B. puti n. sp., known only from the Philippines, and B. hedleyi n. sp., restricted to tropical eastern Australia.

Résumé [+] [-]The genus Lamprohaminoea includes species of colourful haminoeid snails associated with coral reefs and rocky shores in the tropical Indo-West Pacific. In this work, we revise the diversity and systematics of Lamprohaminoea species based on a phylogenetic hypothesis and on a detailed morphological analysis of specimens. Shells, external features of the animals and anatomical characters from the jaws, radula, gizzard plates, and male reproductive system were studied by optical and scanning electron microscopy. Additionally, a molecular species delimitation analysis based on the Automatic Barcode Gap Discovery method using DNA sequences of the cytochrome c oxidase subunit I was implemented. Five species were recognised, three of them new to science, namely L. cymbalum, L. ovalis, L. vamiziensis sp. nov., L. evelinae sp. nov., and L. mikkelsenae sp. nov. Morphologically, these species can be separated by subtle differences of their external colouration and by features of the male reproductive system. Lamprohaminoea vamiziensis sp. nov. is known only from the western Indian Ocean and L. evelinae sp. nov., from the west Pacific, whereas the other three occur across the Indo-West Pacific realm.

Résumé [+] [-]Brachyuran crabs belonging to the subfamily Ethusinae Guinot, 1977, family Dorippidae MacLeay, 1838, are adapted to carry bivalve shells or other objects on their backs by using the hooked dactyli of their last two pairs of pereopods (P4 and P5), which are dorsally located and mobile. Most species inhabit deep water and are infrequently collected. The taxonomy of the 57 known Indo-West Pacific species of ethusines is revised. The subfamily consists of three genera: Ethusa Roux, 1830, with 30 species of which four are being described as new, Ethusina Smith, 1884, with 25 species of which eight are new, and Parethusa Chen, 1997, with two species of which one is new. Ethusa and Ethusina are worldwide in distribution while Parethusa is exclusive to the Indo-West Pacific region. Seven nominal species described by other authors were found to be junior subjective synonyms of other species: Ethusa major Chen, 1993, of Ethusa orientalis Miers, 1886; Ethusa makasarica Chen, 1993, of Ethusa hirsuta McArdle, 1900; Ethusa madagascariensis Chen, 1987, of Ethusa zurstrasseni Doflein, 1904; Ethusina investigatoris (Alcock, 1896) and E. alcocki Ng & Ho, 2003, of Ethusina robusta Miers, 1886; Ethusina insolita Ng & Ho, 2003, of Ethusina dilobotus Chen, 1993; and Ethusina saltator Ng & Ho, 2000, of Ethusina paralongipes Chen, 1993.

Résumé [+] [-]Seguenzioidea and Trochoidea are substantial parts of the biodiversity in the Indo-Pacific. While many Japanese, Australian, New Caledonian and New Zealand species have been studied and described recently, these superfamilies remain unsatisfactory known in the Philippines. Modern collecting resulted in the discovery of many new species. Others are well presented in collections worldwide but most often they bear names of mainly Japanese species, occasionally of Australian or Indian Ocean species. These names have been used as "megaspecies-names" for a vast part of the Indo-Pacific mollusca. We here document 178 species collected in the Philippines, either by Conchology, Inc. Or the Museum National d'Histoire Naturelle, Paris (hereafter referred to as MNHN). The first author is a fan of Trochidae since three decades, from where this publication, which is the result of three years collecting by hundreds of fisherman, scientists and divers. We therefore enlighten this book with photographs of the area, the events, living animals and the people.

Résumé [+] [-]The superfamily Conoidea is one of the most speciose groups of marine mollusks, with estimates of about 340 recent valid genera and subgenera, and 4000 named living species. Previous classifications were based on shell and anatomical characters, and clades and phylogenetic relationships are far from well assessed. Based on a dataset of ca. 100 terminal taxa belonging to 57 genera, information provided by fragments of one mitochondrial (COI) and three nuclear (28S, 18S and H3) genes is used to infer the first molecular phylogeny of this group. Analyses are performed on each gene independently as well as for a data matrix where all genes are concatenated, using Maximum Likelihood, Maximum Parsimony and Bayesian approaches. Several well-supported clades are defined and are only partly identifiable to currently recognized families and subfamilies. The nested sampling used in our study allows a discussion of the classification at various taxonomical levels, and several genera, subfamilies and families are found polyphyletic.

Résumé [+] [-]DNA sequences are currently used to propose primary hypotheses of species delimitation, especially when morphological variability is difficult to assess. In an integrative taxonomy framework, these hypotheses are then compared with other characters, such as morphology or geography, to produce robust species delimitations. For this purpose, the cytochrome oxidase subunit I (COI) gene has been sequenced for almost 50 specimens of the genus Benthomangelia, a deep-sea marine gastropod genus, collected in the South-West Pacific. Five genetic groups, displaying low and high genetic distances respectively within and between groups, were defined. COI hypotheses were compared with both the results obtained with the independent nuclear 28S gene and with an elliptic Fourier analysis of the shape of the last whorl of the shell. 28S gene analysis confirmed the same well-supported groups as COI, and elliptic Fourier analysis identified several morphological characters that vary similarly to genetic variability.

Résumé [+] [-]The superfamily Conoidea is one of the most speciose groups of marine molluses, with almost 700 genera and 10,000 living species. Previous classifications were based on morphological and anatomical characters, but clades and phylogenetic relationships were not well assessed. Information provided by one mitochondrial (COI) and three nuclear (28S, 18S, and H3) genes were used to infer the phylogeny of this group. Data were obtained from more than 100 specimens, belonging to 54 genera, collected during recent cruises in the western Pacific (Philippines, Vanuatu, Norfolk Ridge, and Chesterfield and Solomon Islands). Analyses were performed on each gene independently as well as for a data matrix where all genes were concatenated, using several methods (ML, Parsimony, Bayesian). Some families and subfamilies among Conoidea correspond to well-supported clades uniformly recovered with all genes and all methods, but others appear to be polyphyletic. Several bathyal and abyssal genera are also shown to he polyphyletic. Our results also point out some new phylogenetic relationships at the family, subfamily, and genus levels.

Puillandre N., Sysoev A.V., Olivera B.M., Couloux A. & Bouchet P. 2010. Loss of planktotrophy and speciation: geographical fragmentation in the deep-water gastropod genus Bathytoma (Gastropoda, Conoidea) in the western Pacific. Systematics and Biodiversity 8(3): 371-394. DOI:10.1080/14772001003748709
Résumé [+] [-]Dispersal capabilities are crucial in how speciation patterns are determined in marine invertebrates. Species possessing a long-living planktonic larva apparently have a dispersal advantage over those with non-planktotrophic development, and their distant populations may exchange genetic material, maintaining a broad geographical range for the species. Recent species of the gastropod genus Bathytoma (Conoidea) are all characterized by non-planktotrophic development, having most probably lost a free-swimming larva in the pre-Pliocene, as Miocene fossils have protoconchs indicating planktotrophic larval development. All have a bathyal distribution (100–1500 m), which implies that their capability for direct expansion on the bottom is restricted by both deep-sea basins and shallow-water areas, especially in insular West and South-West Indo-Pacific. Therefore, it can be hypothesized that Bathytoma populations should represent numerous, mostly allopatric taxa restricted to a single or contiguous island groups. We tested this hypothesis using molecular and morphological characters independently. One hundred and thirty-eight specimens from the Philippines, Solomons, Vanuatu, and the Coral Sea were sequenced for one mitochondrial (COI) and one nuclear (ITS2) gene, and 14 operational molecular units were recognized. When these molecular units are overlaid over shell characters, 13 species (11 unnamed) and one form of uncertain status are recognized: three occur in the Philippines, six in the Solomons and one in New Caledonia. Broad distributions (inter-archipelagic) are uncommon (three species). On the whole, the phylogeographic pattern of the diversity in the genus is rather complex and probably also reflects processes of sympatric and fine-scale allopatric speciation, and local extinctions. The eleven new species are described and named.

Résumé [+] [-]The superfamily Conoidea constitutes one of the most diverse and taxonomically challenging groups among marine molluscs. Classifications based on shell or radular characters are highly contradictory and disputed. Whereas the monophyly of the Conidae and Terebridae has not been challenged, the other constituents of the superfamily are placed in a 'trash' group, the turrids, the non-monophyly of which has been demonstrated by anatomical and molecular evidence. We present here a new molecular phylogeny based on a total of 102 conoidean genera (87 'turrids', 5 cones and 10 terebrids) and three mitochondrial genes [cytochrome oxidase I (COI), 12S rRNA and 16S rRNA]. The resulting tree recognizes 14 clades. When the Conidae (Conus s.l.) and Terebridae are ranked as families for consistency of usage, the 'turrids' must be split into 12 families of comparable rank. A new genus-level classification of the Conoidea is published in an accompanying paper.

Résumé [+] [-]Accelerating the description of biodiversity is a major challenge as extinction rates increase. Integrative taxonomy combining molecular, morphological, ecological and geographical data is seen as the best route to reliably identify species. Classic molluscan taxonomic methodology proposes primary species hypotheses (PSHs) based on shell morphology. However, in hyperdiverse groups, such as the molluscan family Turridae, where most of the species remain unknown and for which homoplasy and plasticity of morphological characters is common, shell-based PSHs can be arduous. A four-pronged approach was employed to generate robust species hypotheses of a 1000 specimen South-West Pacific Turridae data set in which: (i) analysis of COI DNA Barcode gene is coupled with (ii) species delimitation tools GMYC (General Mixed Yule Coalescence Method) and ABGD (Automatic Barcode Gap Discovery) to propose PSHs that are then (iii) visualized using Klee diagrams and (iv) evaluated with additional evidence, such as nuclear gene rRNA 28S, morphological characters, geographical and bathymetrical distribution to determine conclusive secondary species hypotheses (SSHs). The integrative taxonomy approach applied identified 87 Turridae species, more than doubling the amount previously known in the Gemmula genus. In contrast to a predominantly shell-based morphological approach, which over the last 30 years proposed only 13 new species names for the Turridae genus Gemmula, the integrative approach described here identified 27 novel species hypotheses not linked to available species names in the literature. The formalized strategy applied here outlines an effective and reproducible protocol for large-scale species delimitation of hyperdiverse groups.

Résumé [+] [-]We present a large-scale molecular phylogeny that includes 320 of the 761 recognized valid species of the cone snails (Conus), one of the most diverse groups of marine molluscs, based on three mitochondrial genes (COI, 16S rDNA and 12S rDNA). This is the first phylogeny of the taxon to employ concatenated sequences of several genes, and it includes more than twice as many species as the last published molecular phylogeny of the entire group nearly a decade ago. Most of the numerous molecular phylogenies published during the last 15 years are limited to rather small fractions of its species diversity. Bayesian and maximum likelihood analyses are mostly congruent and confirm the presence of three previously reported highly divergent lineages among cone snails, and one identified here using molecular data. About 85% of the species cluster in the single Large Major Clade; the others are divided between the Small Major Clade (12%), the Conus californicus lineage (one species), and a newly defined clade (3%). We also define several subclades within the Large and Small major clades, but most of their relationships remain poorly supported. To illustrate the usefulness of molecular phylogenies in addressing specific evolutionary questions, we analyse the evolution of the diet, the biogeography and the toxins of cone snails. All cone snails whose feeding biology is known inject venom into large prey animals and swallow them whole. Predation on polychaete worms is inferred as the ancestral state, and diet shifts to molluscs and fishes occurred rarely. The ancestor of cone snails probably originated from the Indo-Pacific; rather few colonisations of other biogeographic provinces have probably occurred. A new classification of the Conidae, based on the molecular phylogeny, is published in an accompanying paper.

Molecular Phylogenetics and Evolution 80: 186-192. DOI:10.1016/j.ympev.2014.06.024
Résumé [+] [-]Cone snails have long been studied both by taxonomists for the diversity of their shells and by biochemists for the potential therapeutic applications of their toxins. Phylogenetic approaches have revealed that different lineages of Conus evolved divergent venoms, a property that is exploited to enhance the discovery of new conotoxins, but is rarely used in taxonomy. Specimens belonging to the Indo-West Pacific Conus lividus species complex were analyzed using phenetic and phylogenetic methods based on shell morphology, COI and 28S rRNA gene sequences and venom mRNA expression and protein composition. All methods converged to reveal a new species, C. conco n. sp. (described in Supplementary data), restricted to the Marquesas Islands, where it diverged recently (_3 mya) from C. lividus. The geographical distribution of C. conco and C. lividus and their phylogenetic relationships suggest that the two species diverged in allopatry. Furthermore, the diversity of the transcript sequences and toxin molecular masses suggest that C. conco evolved unique toxins, presumably in response to new selective pressure, such as the availability of new preys and ecological niches. Furthermore, this new species evolved new transcripts giving rise to original toxin structures, probably each carrying specific biological activity.

Résumé [+] [-]Mollusks are an invaluable resource in the Philippines, but recent reviews on the status of museum collections of mollusks or research trends in the country are lacking. Such assessments can contribute to a more comprehensive evaluation of natural history museums in the Philippines, as well as biodiversity management. This review showed that local museums in the Philippines have much to improve in terms of their accessibility and geographic coverage in order to effectively cater to research and conservation needs of the country. Online access to databases was lacking for local museums, making it cumbersome to retrieve collection information. The UST museum held the most species and subspecies across all museums (4899), comparable to the national museums of countries such as the USA and France. In terms of size, there were larger Philippine mollusk collections in museums abroad. Majority of mollusk specimens come from Regions 4 and 7, while the CAR and Region 12 were least sampled. Publications on Philippine mollusks are dominated by taxonomic and biodiversity research. Around 80% of publications were on marine species. Therefore, there is a great need to (1) improve access to collections by publishing databases and collections online; (2) improve spatial coverage of mollusk sampling to have a better nationwide (and habitat) representation of Philippine mollusk diversity; (3) fill important knowledge gaps in the ecological assessment of exploited mollusks and minor taxa that will be useful in status assessment and management; and (4) build a network of functional museums to facilitate mollusk and invertebrate researches and conservation by making properly curated specimens available to more researchers nationwide.

We sequenced a fragment of the cox1 gene for 82 specimens covering a large part of its distribution and most type localities. Two delimitation methods were applied, one based on genetic distance (ABGD) and one based on phylogenetic trees (GMYC). All analyses suggest that specimens identified as B. granularis comprise four distinct species: one limited to the tropical western Atlantic, another to southwestern Western Australia and two in the Indo-Pacific (from the Red Sea to the open Pacific) that are partly sympatric—but not syntopic—in Japan, the Philippines, Vanuatu and New Caledonia. Based on comparison of shell characters, we applied the following available names to the four species, respectively: B. cubaniana (d’Orbigny, 1841), B. elisabettae Nappo, Pellegrini & Bonomolo, 2014, B. granularis s. s. and B. affinis Broderip, 1833. We provide new standardized conchological descriptions for each of them. Our results demonstrate that a long planktotrophic larval stage, common among Tonnoidea, does not necessarily ensure a circumtropical species distribution.

Résumé [+] [-]With 59 Recent species, Bursidae, known as «frog shells», are a small but widely distributed group of tropical and subtropical gastropods that are most diverse in the Indo-West Pacific. The present study is aimed at recon structing phylogenetic relationships of bursid gastropods based on extensive and representative taxon sampling. Five genetic markers (cytochrome c oxidase subunit I (cox1), 16 s and 12 s rRNA mitochondrial genes, 28 s rRNA and Histone H3 nuclear gene) were sequenced for over 30 species in every known genus but Crossata. Furthermore, we sequenced the complete mt-genome of 9 species (10 specimens) (Aspa marginata, Marsupina bufo, Korrigania quirihorai, Korrigania fijiensis, Tutufa rubeta, Bursa lamarckii, Lampasopsis rhodostoma (twice), Bufonaria perelegans and Bursa aff. tuberosissima). Our analysis recovered Bursidae as a monophyletic group, whereas the genus Bursa was found to be polyphyletic. The genera Talisman and Dulcerana are resurrected and the genera Alanbeuella gen. nov. and Korrigania gen. nov. are described. Dating analysis using 21 extinct taxa for node and simplified tip calibrations was performed, showing a diversification of the group in two phases. Diversification may be linked to tectonic events leading to biodiversity relocation from the western Tethys to ward the Indo-Pacific.

Résumé [+] [-]A new species of fiddler crab, Uca jocelynae sp. nov., belonging to the U. vocans complex, is described from the islands in Western Pacific on the basis of morphological and molecular data. The new species was previously identified with U. neocultrimana (Bott, 1973) (= U. vocans pacificensis Crane, 1975). The two species can be readily distinguished by characters of the male major chelae, carapace features, and the form of the vulvae. The molecular data of parts of the mitochondrial 16S rRNA and cytochrome oxidase I (COI) genes support that both are sister taxa but nevertheless distinct enough to be regarded as separate species. Uca jocelynae is widely distributed from the islands in the Western Pacific, while U. neocultrimana occurs in Fiji and eastwards.

Résumé [+] [-]We present the most comprehensive phylogeny of a globally distributed deep-sea group of gastropods published to date including over 80% of the recognized diversity of the family Scaphandridae. The definition and taxo nomic composition of the Scaphandridae has been hampered by the lack of a sound phylogenetic framework and definition of synapomorphic traits. We used a combination of molecular phylogenetics (Bayesian Inference and Maximum Likelihood) based on five gene markers (cytochrome c oxidase subunit I, 12S rRNA, 16S rRNA, 18S rRNA, and 28S rRNA) and morpho-anatomical characters to redefine the Scaphandridae and its genera. A new classification is proposed with the three genera Nipponoscaphander, Sabatia, and Scaphander. Main differences between genera lie on the shells (shape, parietal callus, spire) and male reproductive system (prostate). The species Hamineobulla kawamurai is reassigned to the closely related family Eoscaphandridae, currently defined mostly based on pleisiomorphic traits. Biogeographically the genus Nipponoscaphander is restricted to the IndoWest Pacific; Sabatia is mostly circumscribed to the Indo-West Pacific, but has one lineage present in the north Atlantic Ocean. Polyphyly across ocean realms prevails in the specious and globally distributed genus Scaphander with multiple speciation events between Indo-Pacific and Atlantic lineages but also with several episodes of cladogenesis within realms. Two rare cases of species with a broad distribution spanning the Indo-West Pacific and Atlantic realms are confirmed (S. meridionalis and S. nobilis)

Résumé [+] [-]Two new species of the family Leptochitonidae, Leptochiton pumilus sp. nov. and Terenochiton nomurai sp. nov. are described from the tropical and subtropical shallow waters of the West Pacific. L. pumilus from the Philippines and Papua New Guinea has a net-like sculpture on the shell which is rather rare feature in the genus. In this genus, so far only three species have hitherto been known in the tropical shallow waters, in contrast to more than 130 other extant species which are living in the deep cold waters and high latitudes. T. nomurai from Ryukyu Islands is the second representative of the genus Terenochiton Iredale, 1914 which was recently reinstated for Leptochiton norfolcensis (Hedley et Hull, 1912), and is characterized by having rudiments of the insertion plates in all valves. T. nomurai closely resembles the type species, but differs in the arrangement of the aesthete pores on the granules of the tegmentum, and less developed rudiments of the insertion plates.

Molecular phylogeny of the Pectinoidea (Bivalvia) indicates Propeamussiidae to be a non-monophyletic family with one clade sister to the scallops (Pectinidae). Molecular Phylogenetics and Evolution 137: 293-299. DOI:10.1016/j.ympev.2019.05.006
Résumé [+] [-]Scallops (Pectinidae) are one of the most diverse families of bivalves and have been a model system in evolutionary biology. However, in order to understand phenotypic evolution, the Pectinidae needs to be placed in a deeper phylogenetic framework within the superfamily Pectinoidea. We reconstructed a molecular phylogeny for 60 species from four of the five extant families within the Pectinoidea using a five gene dataset (12S, 16S, 18S, 28S rRNAs and histone H3). Our analyses give consistent support for the non-monophyly of the Propeamussiidae, with a subset of species as the sister group to the Pectinidae, the Propeamussiidae type species as sister to the Spondylidae, and the majority of propeamussiid taxa sister to the Spondylidae + Pr. dalli. This topology represents a previously undescribed relationship of pectinoidean families. Our results suggest a single origin for eyes within the superfamily and likely multiple instances of loss for these characters. However, it is now evident that reconstructing the evolutionary relationships of Pectinoidea will require a more comprehensive taxonomic sampling of the Propeamussiidae sensu lato.

Résumé [+] [-]Cerithium koperbergi is a rare gastropod of the family Cerithiidae from the tropical Indo-West Pacific. The species has a small, unusual shell and often inhabits deeper water, fore-reef habitats that are atypical for the genus. Anatomical investigations reveal that it possesses a combination of features heretofore considered diagnostic of two main cerithiid subfamilies: Cerithiinae and Bittiinae. While the shell is bittiine, the animal lacks mesopodial pedal glands and possesses a seminal receptacle (vs. a spermatophore bursa) in the lateral lamina of the oviduct, which are considered to be cerithiine features. Re-evaluation of the anatomy of Bittium reticulatum, the type species of Bittium, indicates the defining anatomical difference in oviduct anatomy between the two subfamilies does not stand up to closer scrutiny. Partial mitochondrial cytochrome c oxidase I (COI) sequences support the interpretation that C. koperbergi is a species complex around the western Pacific rim comprising three divergent mitochondrial lineages. Bayesian analysis of partial mitochondrial COI and 16S rRNA sequences confirm the placement of the C. koperbergi complex within a monophyletic Bittiinae, despite the apparent absence of a unifying anatomical feature. Species in the C. koperbergi complex are here united in Pictorium nov. gen. and two species are described as new. It is hypothesized that features of the midgut may be diagnostic of the Bittiinae, but more comparative data are needed.

Résumé [+] [-]The genus Clea from SE Asia is from one of only two unrelated families among the megadiverse predatory marine Neogastropoda to have successfully conquered continental waters. While little is known about their anatomy, life history and ecology, interest has grown exponentially in recent years owing to their increasing popularity as aquarium pets. However, the systematic affinities of the genus and the validity of the included species have not been robustly explored. Differences in shell, operculum and radula characters support separation of Clea as presently defined into two distinct genera: Clea, for the type species Clea nigricans and its allies, and Anentome for Clea helena and allies. A five-gene mitochondrial (COI, 16S, 12S) and nuclear (H3, 28S) gene dataset confirms the placement of Anentome as a somewhat isolated offshoot of the family Nassariidae and sister to the estuarine Nassodonta. Anatomical data corroborate this grouping and, in conjunction with their phylogenetic placement, support their recognition as a new subfamily, the Anentominae. The assassin snail Anentome helena, a popular import through the aquarium trade so named for their voracious appetite for other snails, is found to comprise a complex of at least four species. None of these likely represents true Anentome helena described from Java, including a specimen purchased through the aquarium trade under this name in the US and one that was recently found introduced in Singapore, both of which were supported as conspecific with a species from Thailand. The introduction of Anentome “helena” through the aquarium trade constitutes a significant threat to native aquatic snail faunas which are often already highly imperiled. Comprehensive systematic revision of this previously unrecognized species complex is urgently needed to facilitate communication and manage this emerging threat.

Résumé [+] [-]A new genus, Limatium gen. n., and two new species, L. pagodula sp. n. and L. aureum sp. n. are described, found on outer slopes of barrier reefs and fringing reefs in the South Pacific. They are rare for cerithiids, which typically occur in large populations. The two new species are represented by 108 specimens sampled over a period of 30 years, only 16 of which were collected alive. Three subadults from the Philippines and Vanuatu likely represent a third species. In addition to their rarity, Limatium species are atypical for cerithiids in their smooth, polished, honey to golden brown shells with distinctive white fascioles extending suture to suture. The radula presents a unique morphology that does not readily suggest an affinity to any of the cerithiid subfamilies. Two live-collected specimens, one of each species and designated as holotypes, were preserved in 95% ethanol and sequenced. Bayesian analysis of partial COI and 16S rDNA sequences demonstrates a placement in the Bittiinae, further extending our morphological concept of the subfamily.

Molecular Phylogenetics and Evolution 130: 18-34. DOI:10.1016/j.ympev.2018.09.016
Résumé [+] [-]The Tonnoidea is a moderately diverse group of large, predatory gastropods with ∼360 valid species. Known for their ability to secrete sulfuric acid, they use it to prey on a diversity of invertebrates, primarily echinoderms. Tonnoideans currently are classified in seven accepted families: the comparatively well known, shallow water Bursidae, Cassidae, Personidae, Ranellidae, and Tonnidae, and the lesser-known, deep water Laubierinidae and Pisanianuridae. We assembled a mitochondrial and nuclear gene (COI, 16S, 12S, 28S) dataset for ∼80 species and 38 genera currently recognized as valid. Bayesian analysis of the concatenated dataset recovered a monophyletic Tonnoidea, with Ficus as its sister group. Unexpectedly, Thalassocyon, currently classified in the Ficidae, was nested within the ingroup as the sister group to Distorsionella. Among currently recognized families, Tonnidae, Cassidae, Bursidae and Personidae were supported as monophyletic but the Ranellidae and Ranellinae were not, with Cymatiinae, Ranella and Charonia supported as three unrelated clades. The Laubierinidae and Pisanianuridae together form a monophyletic group. Although not all currently accepted genera have been included in the analysis, the new phylogeny is sufficiently robust and stable to the inclusion/exclusion of nonconserved regions to establish a revised family-level classification with nine families: Bursidae, Cassidae, Charoniidae, Cymatiidae, Laubierinidae, Personidae, Ranellidae, Thalassocyonidae and Tonnidae. The results reveal that many genera as presently circumscribed are para- or polyphyletic and, in some cases support the rescue of several genus-group names from synonymy (Austrosassia, Austrotriton, Laminilabrum, Lampadopsis, Personella, Proxicharonia, Tritonoranella) or conversely, support their synonymization (Biplex with Gyrineum). Several species complexes are also revealed that merit further investigation (e.g., Personidae: Distorsio decipiens, D. reticularis; Bursidae: Bursa tuberosissima; Cassidae: Echinophoria wyvillei, Galeodea bituminata, and Semicassis bisulcata). Consequently, despite their teleplanic larvae, the apparently circumglobal distribution of some tonnoidean species is the result of excessive synonymy. The superfamily is estimated to have diverged during the early Jurassic (∼186 Ma), with most families originating during a narrow ∼20 My window in Albian-Aptian times as part of the Mesozoic Marine Revolution.

Résumé [+] [-]Eye reduction occurs in many troglobitic, fossorial, and deep-sea animals but there is no clear consensus on its evolutionary mechanism. Given the highly conserved and pleiotropic nature of many genes instrumental to eye development, degeneration might be expected to follow consistent evolutionary trajectories in closely related animals. We tested this in a comparative study of ocular anatomy in solariellid snails from deep and shallow marine habitats using morphological, histological, and tomographic techniques, contextualized phylogenetically. Of 67 species studied, 15 lack retinal pigmentation and at least seven have eyes enveloped by surrounding epithelium. Independent instances of reduction follow numerous different morphological trajectories. We estimate eye loss has evolved at least seven times within Solariellidae, in at least three different ways: characters such as pigmentation loss, obstruction of eye aperture, and “lens” degeneration can occur in any order. In one instance, two morphologically distinct reduction pathways appear within a single genus, Bathymophila. Even amongst closely related animals living at similar depths and presumably with similar selective pressures, the processes leading to eye loss have more evolutionary plasticity than previously realized. Although there is selective pressure driving eye reduction, it is clearly not morphologically or developmentally constrained as has been suggested by previous studies.

Résumé [+] [-]Although species of the chemosymbiotic bivalve family Lucinidae are often diverse and abundant in shallow water habitats such as seagrass beds, new discoveries show that the family is equally speciose at slope and bathyal depths, particularly in the tropics, with records down to 2500m. New molecular analyses including species from habitats down to 2000m indicate that these cluster in four of seven recognized subfamilies: Leucosphaerinae, Myrteinae, Codakiinae, and Lucininae, with none of these comprising exclusively deep-water species. Amongst the Leucosphaerinae, Alucinoma, Epidulcina, Dulcina, and Myrtina live mainly at depths greater than 200m. Most Myrteinae inhabit water depths below 100m, including Myrtea, Notomyrtea, Gloverina, and Elliptiolucina species. In the Codakinae, only the Lucinoma clade live in deep water; Codakia and Ctena clades are largely restricted to shallow water. Lucininae are the most speciose of the subfamilies but only four species analyzed, Troendleina sp., Epicodakia' falkandica, Bathyaustriella thionipta, and Cardiolucina quadrata, occur at depths greater than 200m. Our results indicate that slope and bathyal lucinids have several and independent originations from different clades with a notable increased diversity in Leucosphaerinae and Myrteinae. Some of the deep-water lucinids (e.g. Elliptiolucina, Dulcina, and Gloverina) have morphologies not seen in shallow water species, strongly suggesting speciation and radiation in these environments. By contrast, C.quadrata clusters with a group of shallow water congenors. Although not well investigated, offshore lucinids are usually found at sites of organic enrichment, including sunken vegetation, oxygen minimum zones, hydrocarbon seeps, and sedimented hydrothermal vents. The association of lucinids with hydrocarbon seeps is better understood and has been traced in the fossil record to the late Jurassic with successions of genera recognized; Lucinoma species are particularly prominent from the Oligocene to present day.(c) 2013 The Linnean Society of London, Biological Journal of the Linnean Society, 2014, 111, 401-420.

Résumé [+] [-]A new molecular phylogeny of the Lucinidae using 18S and 28S rRNA and cytochrome b genes includes many species from the tropical Western Atlantic as well as additional taxa from the Indo-West Pacific. This study provides a phylogenetic framework for a new taxonomy of tropical Western Atlantic lucinids. The analysis confirmed five major clades—Pegophyseminae, Leucosphaerinae, Myrteinae, Codakiinae and Lucininae, with Monitilorinae and Fimbriinae represented by single species. The Leucosphaerinae are expanded and include Callucina winckworthi and the W. Atlantic Myrtina pristiphora that groups with several Indo-West Pacific Myrtina species. Within the Codakiinae two abundant species of Ctena from the Western Atlantic with similar shells are discriminated as C. orbiculata and C. imbricatula, while in the Indo-West Pacific Ctena bella is a probable species complex. The Lucininae is the most species rich and disparate subfamily with several subclades apparent. Three species of Lucina are recognized in the W. Atlantic L. aurantia, L. pensylvanica and L. roquesana. Pleurolucina groups near to Cavilinga and Lucina, while Lucinisca muricata is more closely related to the E. Pacific L. fenestrata than to the Atlantic L. nassula. A new species of Parvilucina is identified from molecular analyses having been confounded with Parvilucina pectinata but differs in ligament structure. Also, the former Parvilucina clenchi is more distant and assigned to Guyanella.

Résumé [+] [-]Sixty-three Cardiidae species (including Tridacninae) sampled by the 2004 Panglao Marine Biodiversity Project (PMBP) to Panglao, Philippines, and the PANGLAO 2005 Deep-Sea Cruise are described. In addition, Cardiidae species lists of the Philippine Cuming Tour 2005 and AURORA 2007 expedition are provided. Four species are new to science: Fragum grasi spec. nov., Frigidocardium helios spec. nov., F. sancticaroli spec. nov. and Microcardium velatum spec. nov. For the following six species this paper includes the first published records for the Philippines: Acrosterigma dianthinum (Melvill & Standen, 1899), F. torresi (E.A. Smith, 1885), Fulvia (Laevifulvia) subquadrata Vidal & Kirkendale, 2007, Microfragum erugatum (Tate, 1889), M. subfestivum (Vidal & Kirkendale, 2007) and Vasticardium sewelli (Prashad, 1932). Indo-Pacific range extensions for several other species are given. Ecological data support assignment of Afrocardium to Orthocardiinae. Cardium (Ctenocardia) victor Angas, 1872 and Cardium bomasense Martin, 1917 are transferred to Freneixicardia, the former being the sole extant representative of the genus, and of which Cardium (Trachycardium) hulshofi Pannekoek, 1936 is a new synonym. Based on shell morphology, it is shown that the current variously adopted generic assignments of Cardium lobulatum Deshayes, 1855, C. attenuatum G.B. Sowerby 2nd, 1841, C. biradiatum Bruguière, 1789 and C. multipunctatum G.B. Sowerby 1st in Broderip & Sowerby 2nd, 1833 are unsatisfactory. As a consequence, the alleged Indo-Pacific presence of the genus Laevicardium is questionable. Fulvia (Laevifulvia) imperfecta Vidal & Kirkendale, 2007 is a new synonym of “Laevicardium” lobulatum Deshayes, 1855. Habitat preferences of the taxa encountered during PMBP 2004 are defined, based on four main macro-habitat categories. SEM photos, showing the early ontogenetic stages, demonstrate markedly allomorphic growth of some taxa. Description of the process of development to the terminal shell shape provides a more complete species concept and rigorous species delimitation.

Résumé [+] [-]The genus Nemocardium Meek, 1876, is traditionally considered a relict of the past. Morphometric and morphological analyses reveal that the well-known species N. bechei (Reeve, 1847) is in need of taxonomic reconsideration. In this paper, five species are recognized, three of which are new to science: N. bechei from Taiwan, Philippines and Indonesia; N. probatum (Iredale, 1927) from northern Australia; N. australojaponicum spec. nov. From southern Japan and Korea; N. enigmaticum spec. nov. From the SouthWest Pacific and N. fulvum spec. nov. from Mozambique, Madagascar, Seychelles, India, Philippines and Vanuatu. All but the last species seem to occur perfectly parapatrically. With N. fulvum spec. nov., which is not confined to the Central Indo-Pacific but covers large parts of the Indian Ocean as well, the longitudinal range of Nemocardium is much wider than hitherto thought. A substitute lectotype is designated for Cardium bechei Reeve, 1847, and the New Zealand genus Varicardium Marwick, 1944, is synonymized with Nemocardium.

Tsang L.M., Chan T., Cheung M. & Chu K.H. 2009. Molecular evidence for the Southern Hemisphere origin and deep-sea diversification of spiny lobsters (Crustacea: Decapoda: Palinuridae). Molecular Phylogenetics and Evolution 51(2): 304-311. DOI:10.1016/j.ympev.2009.01.015
Résumé [+] [-]Spiny lobsters (family Palinuridae) are economically important marine animals that have been the subject of a considerable amount of research, However, the phylogeny of this group remains disputed, Morphological analyses have not been able to resolve the relationships of the various members of the group, and no agreement has yet been reached on its phylogeny as indicated by the different gene trees reported to date. In the present study, we attempt to reconstruct the phylogeny of Palinuridae and its allies using sequences from three nuclear Protein-coding genes (phosphoenolpyruvate carboxykinase, sodium-potassium ATPase alpha- subunit and histone 3). The inferred topology receives strong nodal support for most of the branches. The family Palinuridae is found to be paraphyletic with the polyphyletic Synaxidae nested within it. Stridentes forms a monophyletic assemblage, indicating that the stridulating sound producing Organ evolved only once in the spiny lobsters. By contrast, Silentes is paraphyletic, as Palinurellus is more closely related to Stridentes than to other Silentes genera. The three genera restricted to the southern high latitudes Jasus, Projasus and Sagmariasus) constitute the basal lineages in the spiny lobsters, suggesting a Southern Hemisphere origin for the group. Subsequent diversification appears to have been driven by the closure of the Tethys Sea and the formation of the Antarctic circumpolar current, which isolated the northern and southern taxa. Contrary to an earlier hypothesis that postulated evolution from a deep-sea ancestral stock, the shallow-water genus Panulirus is the basal taxon in Stridentes, while the deep-sea genera Puerulus and Linuparus are found to be derived. This indicates that the spiny lobsters invaded deep-sea habitats from the shallower water rocky reefs and then radiated. Our results suggest that Synaxidae is not a valid family, and should be considered to be synonymous with Palinuridae. We also found that the previously proposed subgenera Sagmariasus and Nupalirus are genetically highly diverged, and both warrant a generic status.

Résumé [+] [-]We performed the first cladistic analysis of Metanephrops , the most diverse extant genus of clawed lobster, using a morphology-based data matrix of all 20 species of Metanephrops and 35 cladistically informative characters, all external hard parts. Unweighted cladistic analysis corroborates previous studies that indicated that homoplasy is rampant in the evolution of clawed lobsters. Only 5 of the 68 synapomorphies identified by the analysis are unambiguous, unreversed synapomorphies. Recent species of Metanephrops have traditionally been divided (non-cladistically) into four morphology-based groups. Cladistic analyses support the traditional, arafurensis , Atlantic/ binghami , and japonicus groupings; these groups are monophyletic. The thomsoni group is not supported by the cladogram. The (two) oldest known fossil Metanephrops species occur in Late Cretaceous, shallow marine rocks of the eastern/Atlantic side of the Antarctic Peninsula. The stratigraphic and geographic occurrences of these fossil species are the basis for the previously hypothesized, Late Cretaceous, southern high latitude origin of Metanephrops . Cladistic results corroborate that Metanephrops originated in the southern high latitudes. The cladistically most plesiomorphic single species, the recent M. challengeri , and the next most plesiomorphic species, the Late Cretaceous M. rossensis , are both known from the high southern latitudes. Likewise, the most plesiomorphic species group, the binghami group, is best known from the high southern latitudes.

Tëmkin I. 2010. Molecular phylogeny of pearl oysters and their relatives (Mollusca, Bivalvia, Pterioidea). BMC evolutionary biology 10(342): 1-28
Résumé [+] [-]Background: The superfamily Pterioidea is a morphologically and ecologically diverse lineage of epifaunal marine bivalves distributed throughout the tropical and subtropical continental shelf regions. This group includes commercially important pearl culture species and model organisms used for medical studies of biomineralization. Recent morphological treatment of selected pterioideans and molecular phylogenetic analyses of higher-level relationships in Bivalvia have challenged the traditional view that pterioidean families are monophyletic. This issue is examined here in light of molecular data sets composed of DNA sequences for nuclear and mitochondrial loci, and a published character data set of anatomical and shell morphological characters. Results: The present study is the first comprehensive species-level analysis of the Pterioidea to produce a wellresolved, robust phylogenetic hypothesis for nearly all extant taxa. The data were analyzed for potential biases due to taxon and character sampling, and idiosyncracies of different molecular evolutionary processes. The congruence and contribution of different partitions were quantified, and the sensitivity of clade stability to alignment parameters was explored. Conclusions: Four primary conclusions were reached: (1) the results strongly supported the monophyly of the Pterioidea; (2) none of the previously defined families (except for the monotypic Pulvinitidae) were monophyletic; (3) the arrangement of the genera was novel and unanticipated, however strongly supported and robust to changes in alignment parameters; and (4) optimizing key morphological characters onto topologies derived from the analysis of molecular data revealed many instances of homoplasy and uncovered synapomorphies for major nodes. Additionally, a complete species-level sampling of the genus Pinctada provided further insights into the on-going controversy regarding the taxonomic identity of major pearl culture species.

Résumé [+] [-]The subfamily Cantharidinae Gray, 1857 (Trochoidea: Trochidae) includes 23 recognized genera and over 200 known living species. These marine top shell snails are microphagous grazers that generally live in shallow rocky shores and in macroalgae and seagrass beds of sub-tropical and temperate waters from the Central and Western Indo-Pacific biogeographic regions to the Mediterranean Sea and the Eastern Atlantic Ocean. Recent molecular phylogenetic studies revising the family Trochidae supported the monophyly of the subfamily Cantharidinae and its sister group relationship to the subfamily Stomatellinae. These studies and others has thus far mostly focused on Indo-Pacific members of the subfamily Cantharidinae whereas here, we investigated phylogenetic relationships among their counterparts from the Mediterranean Sea and the North-eastern (NE) Atlantic Ocean including 33 species of genera Gibbula, Jujubinus, Phorcus, Clelandella, and Callumbonella. The Mediterranean and NE Atlantic taxa were supplemented with 30 Indo-Pacific Cantharidinae species plus 19 members of the sister group subfamily Stomatellinae. Phylogenetic trees were constructed using Bayesian inference and maximum likelihood with two datasets comprised of partial sequences of four or six mitochondrial (cox1, rrnL, rrnS, and cob) and nuclear (28S rRNA and histone H3) genes. A clade comprised of all Mediterranean and NE Atlantic taxa was recovered with high support, but its sister group among the Indo-Pacific lineages could not be determined with confidence (although the assignment of “Trochus” kotschyi to Priotrochus could be rejected). Within the Mediterranean and NE Atlantic clade, genera Phorcus and Jujubinus were recovered as reciprocally monophyletic, and the deep-sea genera Clelandella and Callumbonella were placed with high support as sister to Jujubinus. However, the genus Gibbula as currently defined was not monophyletic and constituent species were divided into three major clades and two independent lineages. Phylogenetic relationships among Phorcus, Jujubinus (plus Clelandella and Callumbonella), and the different clades of Gibbula were not fully resolved but received higher support in the phylogenetic analyses based on six genes. A first approach to resolve phylogenetic relationships within Stomatellinae was conducted showing that the diversity of the subfamily is highly underestimated at present, and that Calliotrochus is possibly a member of this subfamily. A chronogram was reconstructed using an uncorrelated relaxed lognormal molecular clock and the origin of the Mediterranean and NE Atlantic clade was dated right after the Azolla phase in the Middle Eocene about 48 million years ago whereas diversification of major clades (genera) followed the eastern closure of the Tethys Ocean in the Middle Miocene about 14 million years ago.

Vidal J. & Kirkendale L. 2007. Ten new species of Cardiidae (Mollusca, Bivalvia) from New Caledonia and the tropical western Pacific. Zoosystema 29(1): 83-107
Résumé [+] [-]The fauna of the tropical Indo-west Pacific is exceptionally diverse but poorly known with even relatively well-studied faunal components yielding new species after careful study, novel approaches (e.g., delineation of cryptic species via molecular analyses) and/or rigorous collection efforts. In an attempt to quantify the biodiversity of the western Pacific molluscan fauna, comprehensive, systematic collecting expeditions have been made since 1978, with a focus on New Caledonia. Building on earlier studies of cardiids from the western Pacific, we report one new genus of cardiid (Pseudofulvia n. gen.) and 10 new cardiid taxa from the area: Acrosterigma capricorne n. sp., Fulvia (Fulvia) colorata n. sp., F. (F.) vepris n. sp., F. (Laevifulvia) subquadrata n. sp., F. (L.) imperfecta n. sp., Pseudofulvia caledonica n. gen., n. sp., P. arago n. gen., n. sp., Ctenocardia gustavi n. sp., C. fi jianum n. sp., C. (Microfragum) subfestivum n. sp. The new species are easily differentiated from conspecifics in details of hinge, dentition, lunular shape and area, rib number and/or rib ornamentation, but often diff er in gross morphological features, such as coloration, shape and size as well. Ctenocardia gustavi n. sp., C. (Microfragum) subfestivum n. sp. and Pseudofulvia caledonica n. gen., n. sp. are relatively large-bodied, with a wide distribution throughout the western Pacifi c. In contrast, Acrosterigma capricorne n. sp. and Pseudofulvia arago n. gen., n. sp. are known only from the Austral Islands and considering the intensive collecting efforts in the region, they appear restricted in their distributions.

Résumé [+] [-]The assignment of species to the vetigastropod genus Solariella Wood, 1842, and therefore the family Solariellidae Powell, 1951, is complicated by the fact that the type species (Solariella maculata Wood, 1842) is a fossil described from the Upper Pliocene. Assignment of species to genera has proved difficult in the past, and the type genus has sometimes acted as a ‘wastebasket’ for species that cannot easily be referred to another genus. In the light of a new systematic framework provided by two recent publications presenting the first molecular phylogenetic data for the group, we reassess the shell characters that are most useful for delimiting genera. Shell characters were previously thought to be of limited taxonomic value above the species level, but this is far from the case. Although overall shell shape is not a reliable character, our work shows that shell characters, along with radular and anatomical characters, are useful for assigning species to genera. Sculpture of the early teleoconch (the region immediately following the protoconch) and the columella are particularly useful characters that have not been used regularly in the past to distinguish genera. However, even with the combination of all morphological characters used in this study (shell, radular and eye), a few species are still difficult to assign to genera and in such cases molecular systematic data are essential. In the present study, we discuss 13 genera—12 of which were recovered as well-supported clades in recent molecular systematic studies—and provide morphological characters to distinguish them. We describe several new taxa: Chonospeira n. gen. (referred to as ‘clade B’ in previous molecular systematic studies), Phragmomphalina n. gen. (Bathymophila in part in molecular systematic studies) and Phragmomphalina vilvensi n. sp. (type species of Phragmomphalina n. gen.). We synonymize Hazuregyra Shikama, 1962 with Minolia A. Adams, 1860, Minolia subangulata Kuroda & Habe, 1952 with Minolia punctata A. Adams, 1860 and M. gemmulata Kuroda & Habe, 1971 with M. shimajiriensis (MacNeil, 1960). We also present the following new combinations: Bathymophila bairdii (Dall, 1889), B. dawsoni (Marshall, 1979), B. regalis (Marshall, 1999), B. wanganellica (Marshall, 1999), B. ziczac (Kuroda & Habe in Kuroda, Habe & Oyama, 1971), Chonospeira nuda (Dall, 1896), C. iridescens (Habe, 1961), C. ostreion (Vilvens, 2009), C. strobilos (Vilvens, 2009), Elaphriella corona (Lee & Wu, 2001), E. diplax (Marshall, 1999), E. meridiana (Marshall, 1999), E. olivaceostrigata (Schepman, 1908), E. opalina (Shikama & Hayashi, 1977), Ilanga norfolkensis (Marshall, 1999), I. ptykte (Vilvens, 2009), I. zaccaloides (Vilvens, 2009), Minolia shimajiriensis (MacNeil, 1960), M. watanabei (Shikama, 1962), Phragmomphalina alabida (Marshall, 1979), P. diadema (Marshall, 1999), P. tenuiseptum (Marshall, 1999), Spectamen euteium (Vilvens, 2009), S. basilicum (Marshall, 1999), S. exiguum (Marshall, 1999) and S. flavidum (Marshall, 1999).

Résumé [+] [-]This study is the most extensive molecular study of the gastropod families Trochidae and Calliostomatidae published to date, in terms of both numbers of taxa and of gene sequences. As a result of Bayesian phylogenetic analyses of molecular sequence data from one nuclear gene and three mitochondrial genes, we propose dramatic changes to Trochidae family systematics, present the first molecular phylogeny for Calliostomatidae and include the first published sequence data for the enigmatic subfamily Thysanodontinae. Our phylogeny demonstrates that within the family Trochidae there is strong support for three subfamilies new to traditional classifications: Alcyninae subfam. nov., Fossarininae and Chrysostomatinae subfam. nov. As proposed, Alcyninae consists only of the nominotypical genus Alcyna, which is sister to all other trochids. The subfamily Fossarininae, as defined here, includes Fossarina, Broderipia, Synaptocochlea and ‘‘Roya” eximia and probably also Clydonochilus and Minopa. The subfamily Chrysostomatinae comprises the genera Chrysostoma and Chlorodiloma. Additional molecular support is also obtained for recently redefined Trochinae, Monodontinae, and Cantharidinae and for the traditionally recognised subfamilies Umboniinae and Stomatellinae. The subfamily Lirulariinae is not supported by the molecular data, but rather is incorporated into Umboniinae. We also demonstrate that the current concept of the subfamily Margaritinae (previously a trochid subfamily, but recently and provisionally assigned to Turbinidae) is not monophyletic. We provide preliminary evidence that whereas Margarella rosea (previously a member of Margaritinae) belongs in the trochid subfamily Cantharidinae, its presumptive congener M. antarctica is not a trochid, but instead clusters with the thysanodontine genus Carinastele. Based on the phylogenetic placement of C. kristelleae, we agree with previous proposals based on morphological data that Thysanodontinae are more closely related to Calliostomatidae than Trochidae. Both Calliostoma and Carinastele are carnivorous and if a sister relationship can be confirmed between Carinastele and Margarella antarctica it might mean that carnivory evolved twice in Trochoidea. The direction of dietary changes was not investigated in this study, but mapping diet onto the phylogeny suggests that true herbivory is predominantly a derived character. The new classification system also means that five trochid subfamilies are predominantly associated with hard substrata, one with soft substrata (Umboniinae) and two with algae and seagrass (Alcyninae and Cantharidinae). There has been a shift back to hard substrata in one umboniine clade. Two of three clades within Calliostomatidae were predominantly associated with hard substrata, but one Japanese clade is associated with sand. The finding of three new, unidentified species from very deep water means that Trochidae, like Calliostomatidae, now includes species found at bathyal depths. More deep-water species may be found as increased sampling leads to the discovery of new species.

Résumé [+] [-]The gastropod superfamily Trochoidea Rafinesque, 1815 is comprised of a diverse range of species, including large and charismatic species of commercial value as well as many small or enigmatic taxa that are only recently being represented in molecular studies. This study includes the first sequences for rarely collected species from the genera Gaza Watson, 1879, Callogaza Dall, 1881, Antimargarita Powell, 1951 and Kaiparathina Laws, 1941. There is also greater taxon sampling of genera that have proved difficult to place in previous phylogenetic analyses, like Tectus Montfort, 1810, Tegula Lesson, 1832, Margarites Gray, 1847, Margarella Thiele, 1893 and trochoid skeneimorphs. There is also greater sampling of poorly represented families Solariellidae and Liotiidae. Bayesian analysis of combined gene data sets based on four (28S, 12S, 16S and COI) or five genes (plus 18S) suggests that there are eight, possibly nine families in Trochoidea including the families Margaritidae and Tegulidae, which are recognized for the first time at familial rank. Other trochoidean families confirmed are Calliostomatidae, Liotiidae, Skeneidae, Solariellidae, Trochidae and Turbinidae. A clade including Cittarium and the commercially important genera Rochia and Tectus may represent a possible ninth family, but this is not formally recognized or described here and awaits confirmation from further studies. Relationships among families were not generally well supported except in the 5-gene tree. In the 5-gene tree, Turbinidae, Liotiidae, Tegulidae, Cittarium, Rochia and Tectus form a well-supported clade consistent with the previous molecular and morphological studies linking these groups. This clade forms another well-supported clade with Margaritidae and Solariellidae. Trochidae is sister to Calliostomatidae with strong support. Subfamilial relationships within Trochidae are consistent with recent molecular studies, with the addition of one new subfamily, Kaiparathininae Marshall 1993 (previously a tribe). Only two subfamilies are recognized within Turbinidae, both with calcareous opercula: Prisogasterinae and Turbininae. Calliostomatidae includes a new subfamily Margarellinae. Its assignment to Calliostomatidae, although well supported by molecular evidence, is surprising considering morphological evidence.

DOI:10.1002/ece3.513
Résumé [+] [-]Recent expeditions have revealed high levels of biodiversity in the tropical deep-sea, yet little is known about the age or origin of this biodiversity, and large-scale molecular studies are still few in number. In this study, we had access to the largest number of solariellid gastropods ever collected for molecular studies, including many rare and unusual taxa. We used a Bayesian chronogram of these deep-sea gastropods (1) to test the hypothesis that deep-water communities arose onshore, (2) to determine whether Antarctica acted as a source of diversity for deep-water communities elsewhere and (3) to determine how factors like global climate change have affected evolution on the continental slope. We show that although fossil data suggest that solariellid gastropods likely arose in a shallow, tropical environment, interpretation of the molecular data is equivocal with respect to the origin of the group. On the other hand, the molecular data clearly show that Antarctic species sampled represent a recent invasion, rather than a relictual ancestral lineage. We also show that an abrupt period of global warming during the Palaeocene Eocene Thermal Maximum (PETM) leaves no molecular record of change in diversification rate in solariellids and that the group radiated before the PETM. Conversely, there is a substantial, although not significant increase in the rate of diversification of a major clade approximately 33.7Mya, coinciding with a period of global cooling at the EoceneOligocene transition. Increased nutrients made available by contemporaneous changes to erosion, ocean circulation, tectonic events and upwelling may explain increased diversification, suggesting that food availability may have been a factor limiting exploitation of deep-sea habitats. Tectonic events that shaped diversification in reef-associated taxa and deep-water squat lobsters in central Indo-West Pacific were also probably important in the evolution of solariellids during the Oligo-Miocene.

Williams S.T., Noone E.S., Smith L.M. & Sumner‐rooney L. 2022. Evolutionary loss of shell pigmentation, pattern, and eye structure in deep‐sea snails in the dysphotic zone. Evolution 76(12): 3026-3040. DOI:10.1111/evo.14647
Résumé [+] [-]Adaptations to habitats lacking light, such as the reduction or loss of eyes and pigmentation, have fascinated biologists for centuries, yet have rarely been studied in the deep sea, the earth's oldest and largest light‐limited habitat. Here, we investigate the evolutionary loss of shell pigmentation, pattern, and eye structure across a family of deep‐sea gastropods (Solariellidae). We show that within our phylogenetic framework, loss of these traits evolves without reversal, at different rates (faster for shell traits than eye structure), and over different depth ranges. Using a Bayesian approach, we find support for correlated evolution of trait loss with increasing depth within the dysphotic region. A transition to trait loss occurs for pattern and eye structure at 400–500 m and for pigmentation at 600–700 m. We also show that one of the sighted, shallow‐water species, Ilanga navakaensis, which may represent the “best‐case” scenario for vision for the family, likely has poor spatial acuity and contrast sensitivity. We therefore propose that pigmentation and pattern are not used for intraspecific communication but are important for camouflage from visual predators, and that the low‐resolution vision of solariellids is likely to require high light intensity for basic visual tasks, such as detecting predators.

Yang C.H., Chen I.S. & Chan T.Y. 2008. A new slipper lobster of the genus Petrarctus (Crustacea: Decapoda: Scyllaridae) from the west pacific. The Raffles Bulletin of Zoology Supplement No. 19: 71-81
Résumé [+] [-]A new species of slipper lobster, Petrarctus holthuisi, new species, is found from the recent expeditions to the Philippines and Vanuatu. The new species resembles P. rugosus (H. Milne Edwards, 1837) but has a different colouration and several morphological differences. Comparisons of the partial sequence of cytochrome c oxidase subunit I (COI) show high degree of divergence (12.5-22.3%) among all the species of Petrarctus. The molecular genetic analysis also suggests that the recent separation of Scyllarus sensu Into may need to be revised. A key to all Petrarctus species is provided.

Yang C.H., Chan T.Y. & Chu K.H. 2010. Two new species of the “Heterocarpus gibbosus Bate, 1888” species group (Crustacea: Decapoda: Pandalidae) from the western Pacific and north-western Australia. Zootaxa 2372: 206-220
Résumé [+] [-]The widely distributed deep-sea caridean shrimp Heterocarpus gibbosus Bate, 1888 was previously believed to exhibit considerable variations in the development of the basal rostral crest. Based on the comparison of abundant material from the western Pacific, combined with a molecular genetic analysis using partial sequences of the mitochondrial COI and 16S rRNA genes, three distinct species could be recognized. The true H. gibbosus has a moderately high basal rostral crest and appears to have a more eastern distribution from the South China Sea to the Indian Ocean. Both forms with a very low or very high basal rostral crest are currently undescribed and mainly distributed along the western coast of the Pacific from Japan to Fiji. The low basal rostral crest form, H. abulbus sp. nov., is unique in the genus by lacking a distinct abdominal boss and appears to be restricted to Japan, Taiwan and NE Philippines. The very high basal rostral crest form, H. corona sp. nov., occurs in the western Pacific down to NW Australia.

Yang C.H. & Chan T.Y. 2012. On the taxonomy of the slipper lobster Chelarctus cultrifer (Ortmann, 1897) (Crustacea: Decapoda: Scyllaridae), with description of a new species. THE RAFFLES BULLETIN OF ZOOLOGY 60(2): 449–460
Résumé [+] [-]The slipper lobster Chelarctus cultrifer (Ortmann, 1897), a putatively wide-spread Indo-West Pacific species, is well-known in Japan. However, recent collections from Taiwan and the Philippines, and comparisons with material from Indonesia and elsewhere revealed that there are actually two species confused under this name. The two species differ markedly in morphology and colour. On the basis of the lectotype designation of C. cultrifer by Holthuis (2002, from Indonesia), the material from Taiwan and Japan is shown to be actually undescribed and is named herein. Chelarctus cultrifer sensu stricto is restricted to the material from the more southern localities in the Philippines westwards to Iles Glorieuses. Genetic comparison of sequences of the barcoding gene, mitochondrial cytochrome c oxidase subunit (COI), supported the species separation. The molecular data further suggested that two genetic forms are present within C. cultrifer sensu stricto, and therefore, the subspecific name C. cultrifer meridionalis (Holthuis, 1960) is resurrected.

Just the once will not hurt: DNA suggests species lumping over two oceans in deep-sea snails (Cryptogemma). Zoological Journal of the Linnean Society 190(2): 532-557. DOI:10.1093/zoolinnean/zlaa010
Résumé [+] [-]Abstract The practice of species delimitation using molecular data commonly leads to the revealing of species complexes and an increase in the number of delimited species. In a few instances, however, DNA-based taxonomy has led to lumping together of previously described species. Here, we delimit species in the genus Cryptogemma (Gastropoda: Conoidea: Turridae), a group of deep-sea snails with a wide geographical distribution, primarily by using the mitochondrial COI gene. Three approaches of species delimitation (ABGD, mPTP and GMYC) were applied to define species partitions. All approaches resulted in eight species. According to previous taxonomic studies and shell morphology, 23 available names potentially apply to the eight Cryptogemma species that were recognized herein. Shell morphometrics, radular characters and geographical and bathymetric distributions were used to link type specimens to these delimited species. In all, 23 of these available names are here attributed to seven species, resulting in 16 synonymizations, and one species is described as new: Cryptogemma powelli sp. nov. We discuss the possible reasons underlying the apparent overdescription of species within Cryptogemma, which is shown here to constitute a rare case of DNA-based species lumping in the hyper-diversified superfamily Conoidea.
