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.
Poppe, Guido T., Tagaro, Sheila P., Dekker, Henk, 2006, The Seguenziidae, Chilodontidae, Trochidae, Calliostomatidae and Solariellidae of the Philippine Islands, with description of 1 new genus, 2 new subgenera, 70 new species and 1 new subspecies., Visaya, Suppl.2, 1-143
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 [+] [-]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.
Castro P., 2007, A reappraisal of the family Goneplacidae MacLeay, 1838 (Crustacea, Decapoda, Brachyura) and revision of the subfamily Goneplacinae, with the description of 10 new genera and 18 new species, Zoosystema, 29, 4, 609-774
Résumé [+] [-]A reappraisal of the taxonomy of the brachyuran crabs belonging to the family Goneplacidae MacLeay, 1838 sensu lato has resulted in the revision of the subfamily Goneplacinae, which combines the subfamilies Goneplacinae MacLeay, 1838 and Carcinoplacinae H. Milne Edwards, 1852. Most of the 66 species of Goneplacinae sensu stricto that are listed herein inhabit relatively deep water and are infrequently collected. The subfamily Goneplacinae sensu stricto now consists of 17 genera of which 10 are being described as new: Carcinoplax H. Milne Edwards, 1852, with 18 species of which four are new; Entricoplax n. gen., monotypic; Exopheticus n. gen., with two species; Goneplacoides n. gen., monotypic; Goneplax Leach, 1814, with four species; Hadroplax n. gen., monotypic; Menoplax n. gen., monotypic; Microgoneplax n. gen., with five species of which four are new; Neogoneplax n. gen., with three species of which two are new; Neommatocarcinus Takeda & Miyake, 1969, monotypic; Notonyx A. Milne-Edwards, 1873, with three species; Ommatocarcinus White, 1852, with four species; Paragoneplax n. gen., monotypic; Psopheticus Wood-Mason, 1892, with four species; Pycnoplax n. gen., with five species of which one is new; Singhaplax Serene & Soh, 1976, with seven species of which four are new; and Thyraplax n. gen., with five species of which three are new. All goneplacine genera are exclusive to the Indo-West Pacific region (plus contiguous temperate areas) except Goneplax, which is so far known mostly from the Atlantic and Mediterranean regions. Four nominal species described by other authors were found to be junior subjective synonyms for other species: Carcinoplax verdensis Rathbun, 1914 and C polita Guinot, 1989 synonymous of C specularis Rathbun, 1914; Goneplax megalops Komatsu & Takeda, 2003 of Goneplacoides marivenae (Komatsu & Takeda, 2003) n. comb.; and Psopheticus insolitus Guinot, 1990 of P stridulans Wood-Mason, 1892.

Résumé [+] [-]Thirty-eight species of leucosiid crabs are reported from Panglao in Bohol, the Central Philippines. Of these, three are new to science: Alox bothros, A. chaunos, and Urnalana cristata, while five constitute new records for the Philippines: Leucosia rubripalma Galil, 2003, Myra tumidospina Galil, 2001, Urnalana elata (A. Milne-Edwards, 1874), U. pulchella (Bell, 1855) and U. whitei (Bell, 1855). The new species are described and illustrated, and their affinities with allied taxa discussed Tokoyo triloba Komatsu, Manual & Takeda, 2005, is also synonymised with T. eburnea (Alcock, 1896).

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 [+] [-]A new genus and species of pontoniine shrimp, Blepharocaris panglao, has been found in Panglao Island in the Philippines. The new genus is unique in the Pontoniinae on account of the orbital rim being laminar and distinctly separated from the leaf-like inferior orbital angle. The relationship of this new genus with other similar pontoniines is discussed.
Ng, Peter K.L., Manuel-Santos, Marivene R., 2007, Establishment of the Vultocinidae, a new family for an unusual new genus and new species of Indo-West Pacific crab (Crustacea: Decapoda: Brachyura: Goneplacoidea), with comments on the taxonomy of the Goneplacidae, Zootaxa, 1558, 39-68
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 [+] [-]Studies of an extensive collection of homolid crabs obtained from various recent expeditions to the Central Philippines revealed the presence of two new species (Latreillopsis mariveneae and Yaldwynopsis saguili) and two new records (Homola ikedai and Paromola macrocheira). Eleven species are now known from the Philippines. The extensive material of many species previously regarded as rare allowed for the taxonomic reappraisal of several supposedly wide-ranging species, and as a result, two new species are described from French Polynesia (Homola poupini and Yaldwynopsis guinotae).

Résumé [+] [-]New collections of deep-sea crabs from the Bohol Sea in Central Philippines have obtained a large series of specimens of the deep-sea spider crabs of the genus Cyrtomaia (Majidae), of which one is here recognised as new, C. largoi, new species. Three other species: C murrayi Miers, 1886, C. horrida Rathbun, 1916, and C. echinata Rathbun, 1916, are all represented by an extensive series of specimens, allowing invaluable insights into their difficult taxonomy and ecology. One nominal subspecies, Cyrtomaia horrida pilosa Ihle & Ihle-Landenberg, 1931, is synonymised with C. horrida.
Tshudy, Dale, Chan, Tin-Yam, Sorhannus, Ulf, 2007, Morphology based cladistic analysis of Metanephrops: the most diverse extant genus of clawed lobster (Nephropidae), Journal of Crustacean Biology, 27, 3, 463–476
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.
Vidal, Jacques, Kirkendale, Lisa, 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 [+] [-]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.

doi: 10.2108/zsj.25.1156 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.

doi: 10.1016/j.ympev.2007.11.007 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 [+] [-]A revision of the terebrid genus Granuliterebra (Oyama, 1961), is carried out, a new terebrid genus, Pellifronia n. gen., and three new terebrid species, Granuliterebra oliverai n. sp., G. eddunhami n. sp., and Myurella lineaperlata n. sp. Are described from the Vanuatu Archipelago. Conchological characters were used in the analysis of specimens gathered from two recent major expeditions to the Vanuatu Archipelago by the Museum national d'Histoire naturelle. A total of 106 terebrid species in the bathymetrical range of 0-200 m, representing the Philippines, New Caledonia and Vanuatu were used in a comparative study. There is a 65% overlap of the terebrid fauna found in Santo and in the Philippines and New Caledonia.

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.

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 [+] [-]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 [+] [-]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.

doi: 10.1016/j.ympev.2008.11.020 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.

doi: 10.1093/molbev/msn211 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 [+] [-]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.

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 [+] [-]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.

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.

Résumé [+] [-]On the basis of fresh collections from various parts of the western Pacific, three species of majoid crabs previously considered as rare are redescribed and figured: Oxypleurodon bidens (Sakai, 1969), O. auritum (Rathbun, 1916) and O. coralliophilum (Takeda, 1980). Four new species are described: O. boholense from the Philippines, O. barazeri and O. parallelum front the Solomon Islands, and O. alaini from New Caledonia. A new genus and new species, Stegopleurodon planirostrum, is described from New Caledonia and Vanuatu. The two species currently assigned to the allied American genus Sphenocarcinus A.

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.
Tsang, Ling Ming, Chan, Tin‐Yam, Cheung, M.K., Chu, Ka Hou, 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.

doi: 10.1016/j.ympev.2010.03.008 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 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.

doi: 10.1007/s10531-009-9744-x 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.

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.
Puillandre, Nicolas, Sysoev, Alexander V., Olivera, Baldomero M., Couloux, Arnaud, Bouchet, Philippe, 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.
Shih, Hsi-Te, Naruse, Tohru, Ng, Peter K.L., 2010, Uca jocelynae sp. nov., a new species of fiddler crab (Crustacea: Brachyura: Ocypodidae) from the Western Pacific, Zootaxa, 2337, 47-62
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.
Tëmkin, Ilya, 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.
Williams, Suzanne T., Donald, K.M., Spencer, H.G., Nakano, Tomoyuki, 2010, Molecular systematics of the marine gastropod families Trochidae and Calliostomatidae (Mollusca: Superfamily Trochoidea), Molecular Phylogenetics and Evolution, 54, 3, 783-809
doi: 10.1016/j.ympev.2009.11.008 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 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.

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.

doi: 10.1093/mollus/eyr017 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 [+] [-]ollections made during recent French expeditions to the Solomon Islands (SALOMON 1 and 2) and Vanuatu (BOA 0 and 1) yielded 10 species of the caridean genus Glyphocrangon A. Milne-Edwards, 1881, including two new to science: G. boa sp. nov. from Vanuatu and G. prostrata sp. nov. from the Solomon Islands. Affinities of these two new species are discussed. The following eight species are newly recorded from the Solomon Islands: G. confusa Komai, 2004, G. faxoni De Man, 1918, G. indonesiensis Komai, 2004, G. lineata Komai, 2004, G. megalophthalma De Man, 1918, G. proxima Komai, 2004, G. pugnax De Man, 1918 and G. similior Komai, 2004. Glyphocrangon demani Komai, 2006 and G. rudis Komai, 2006 are shown to represent the male and female, respectively, of the same species, and the latter name is given priority over the former.

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.

doi: 10.1016/j.ympev.2011.03.022 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.

doi: 10.1093/mollus/eyr015 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.

doi: 10.1016/j.ympev.2012.03.001 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.

doi: 10.1111/j.1365-294X.2012.05743.x 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.

doi: 10.1111/j.1463-6409.2011.00512.x 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 [+] [-]A new genus and species of Fasciolariidae, Angulofusus nedae n. gen. n. sp. conchologically superficially resembling some Conoidea is described. Radula, anatomy and coloration of the body of the new species suggest that it belongs to subfamily Fusininae, being very similar in anatomy to species of the genus Amiantofusus. The species is broadly distributed in the Indo-Pacific, from the Philippines, through Vanuatu and New Caledonia to Wallis and Futuna in 40 to 105 m.

doi: 10.1080/14772000.2012.753137 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.

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.
Kantor, Yuri I., Strong, Ellen E., Puillandre, Nicolas, 2012, A new lineage of Conoidea (Gastropoda: Neogastropoda) revealed by morphological and molecular data, Journal of Molluscan Studies, 78, 3, 246-255
doi: 10.1093/mollus/eys007 Résumé [+] [-]The hyperdiverse group of venomous Conoidea has eluded attempts to construct a robust and stable classification owing to the absence of a robust and stable phylogenetic framework. 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, Yuri I., Puillandre, Nicolas, 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, Yuri I., Puillandre, Nicolas, Rivasseau, Audrey, Bouchet, Philippe, 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 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 [+] [-]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.
Puillandre, Nicolas, Modica, Maria-Victoria, Zhan, Y., Sirovich, L., Boisselier, Marie-Catherine, Cruaud, Corinne, Holford, Mandë, Samadi, Sarah, 2012, Large-scale species delimitation method for hyperdiverse groups: LARGE-SCALE SPECIES DELIMITATION, Molecular Ecology, 21, 11, 2671-2691
doi: 10.1111/j.1365-294X.2012.05559.x 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.

Williams, Suzanne T., 2012, Advances in molecular systematics of the vetigastropod superfamily Trochoidea: Advances in systematics of Trochoidea, Zoologica Scripta, 41, 6, 571-595
doi: 10.1111/j.1463-6409.2012.00552.x 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.

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.
Claremont, Martine, Houart, Roland, Williams, Suzanne T., Reid, David G., 2013, A molecular phylogenetic framework for the Ergalataxinae (Neogastropoda: Muricidae), Journal of Molluscan Studies, 79, 1, 19-29
doi: 10.1093/mollus/eys028 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.

doi: 10.1016/j.ympev.2012.09.014 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 [+] [-]Two new species of the pagurid genus Pylopaguropsis Alcock, 1905 are described and illustrated from the Bohol Sea, the Philippines. Pylopaguropsis pygmaeus, new species, resembles P. keijii McLaughlin & Haig, 1989, P. lemaitrei Asakura & Pauly, 2003, P. lewinsohni McLaughlin & Haig, 1989 and P. zebra (Henderson, 1893) in sharing appreciably dissimilar third pereopods and relatively long ocular peduncles, but differs in having corneas not dilated, and fewer corneous spines on the ventral margins of the dactyls of the ambulatory legs. Pylopaguropsis similis, new species, differs from the closely related species P. bellula Osawa & Okuno, 2007, P. furusei Asakura, 2000, P. laevispinosa McLaughlin & Haig, 1989 and P. vicina Komai & Osawa, 2004, by the relatively long, acute spines on the right palm, the lack of additional dorsal spines or spinules on the carpi of the second pereopods and two rows (rather than one) of corneous scales on the propodal rasp of the fourth pereopod.

doi: 10.1111/ivb.12031 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 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.

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.

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.

doi: 10.5852/ejt.2014.78 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.

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.

doi: 10.1111/zsc.12030 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.

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.

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).

doi: 10.1016/j.ympev.2014.05.023 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.
Puillandre, Nicolas, Stöcklin, Reto, Favreau, Philippe, Bianchi, Estelle, Perret, Frédéric, Rivasseau, Audrey, Limpalaër, Loïc, Monnier, Eric, Bouchet, Philippe, 2014, When everything converges: Integrative taxonomy with shell, DNA and venomic data reveals Conus conco, a new species of cone snails (Gastropoda: Conoidea), 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.

doi: 10.1111/bij.12208 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.

doi: 10.1111/zoj.12278 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.

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.

doi: 10.11646/zootaxa.3913.1.1 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 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.

doi: 10.1111/evo.13022 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.

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.

doi: 10.1111/zoj.12431 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.
