Alf A., Maestrati P. & Bouchet P. 2010. New species of Bolma (Gastropoda: Vetigastropoda: Turbinidae) from the tropical deep sea. The Nautilus 124(2): 93-99
Résumé [+]
[-]
Five new species of Bolma are described, three from New Caledonia, one from Mozambique and one from French Polynesia, all from deep reef (75-155 m) to bathyal (230-580 m) depths. Four of the new species have been sequenced, and their holotypes are also voucher specimens for COl sequences, thus contributing to a new generation of name-bealing types. The descriptions and names are provided in advance of a forthcoming shell-based revision of the genus Bolma, and in advance of a detailed molecular- and morphology-based study of Bolma in New Caledonian waters.

Résumé [+]
[-]
Most species of the genus Bolma Risso, 1826 live in deep water. This may explain why 17 of the 40 species known today were discovered after 1979 when Beu & Ponder published their revision of the genus. Another new species of the genus Bolma from the deep water off New Caledonia is described here. Bolma Boucheti spec. nov. is a small member of the genus, reaching less than 10 mm height. It is compared with Bolma kreipli Alf, Maestrati & Bouchet, 2010, Bolma fuscolineata Alf & Kreipl, 2009, both also from New Caledonia and Bolma microconcha Kosuge, 1985 which is widely spread in the tropical West Pacific.

Résumé [+]
[-]
A new pleurotomariid species, Bayerotrochus belauensis new species, collected from the Palau Islands, western Pacific, is described and illustrated. This new species is most similar in shell morphology to B. teramachii (Kuroda, 1955), from which it may be distinguished by its thinner, lighter shell with a taller, more stepped spire and lack of pronounced spiral sculpture along the shell base. Molecular data (COI) show B. belauensis new species to be more closely related to B. boucheti from New Caledonia and B. delicatus from Yap, than to B. teramachii. Bayerotrochus boucheti (Anseeuw and Poppe, 2001) differs in having a broader, more conical spire, a more depressed aperture, and a more darkly pigmented shell with spiral sculpture on the shell base. The recently described B. delicatus S.-P. Zhang, S.Q. Zhang, and Wei, 2016 is easily distinguished by its much smaller size and distinctive shell profile.

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 [+]
[-]
We investigated the relationships of the muricid subfamilies Haustrinae, Pagodulinae and the genus Poirieria using a molecular phylogenetic approach on a dataset of three mitochondrial genes (12S, 16S and COI). These taxa form a well-supported clade within Muricidae. The phylogenetic analysis suggests that Poirieria is the sister group of Pagodulinae and that Axymene, Comptella, Pagodula, Paratrophon, Trophonella, Trophonopsis, Xymene, Xymenella, Xymenopsis and Zeatrophon are all worthy of genus-level rank within this subfamily. We propose the use of Enixotrophon for a group of species currently classified in Pagodula. The results also support a new taxonomic arrangement in Haustrinae.

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.

Mémoires du Muséum national d'Histoire naturelle 196:269-387, ISBN:978-2-85653-614-8
Résumé [+]
[-]
Shell, radular, opercular and external anatomical characters are surveyed in world Recent deep-water Cassidae, leading to the recognition of three subfamilies: Cassinae, Oocorythinae and Phaliinae. All Recent species are revised of Galeodea Link, 1807 (=Galeoocorys Kuroda & Habe, 1957), Microsconsia n. gen. and Sconsia Gray, 1847, all included in subfamily Cassinae; of Oocorys Fischer,
1883 (= Benthodolium Verrill & Smith, 1884, = Hadroocorys Quinn, 1980), Eucorys n. gen. (including Oocorys bartschi Rehder, 1943 and O. barbouri Clench & Aguayo, 1939) and Dalium Dall, 1889, all included in subfamily Oocorythinae; and of Echinophoria Sacco, 1890, included in subfamily Phaliinae. New species named are Galeodea plauta n. sp. (northwestern New Zealand), Microsconsia limpusi n. sp. (southeastern Queensland, Australia), and Oocorys grandis n. sp. (central Indian Ocean, and southeastern Atlantic, off
Namibia). Galeodea bituminata (Martin, 1933) (based on a Pliocene fossil from Buton Island, Indonesia) is an earlier name for G. echinophorella Habe, 1961; G. carolimartini Beets, 1943 is another earlier name for G. echinophorella. The name usually accepted for the type species of Sconsia, S. striata (Lamarck, 1816), is a junior secondary homonym of S. striata (J. Sowerby, 1812) and the valid name for this species is S. grayi (A. Adams, 1855). Echinophoria kurodai Abbott, 1968 was based on small specimens of E. wyvillei (Watson, 1886), and E. oschei Mühlhäusser, 1992 was based on Indian Ocean specimens of E. wyvillei. Echinophoria carnosa Kuroda & Habe, 1961 is limited to southern Japan to the Philippine Islands.

Gyrothyris williamsi sp. nov. and inter-relationships of some taxa from waters around New Zealand and the southern oceans (Rhynchonelliformea: Terebratelloidea). Earth and Environmental Science Transactions of the Royal Society of Edinburgh 98(3-4). DOI:10.1017/S1755691008075142
Résumé [+]
[-]
This paper describes a terebratelloid articulate brachiopod, Gyrothyris williamsi sp. nov., based on 95 specimens from seamounts on the Lord Howe Rise, Coral Sea, SW Pacific Ocean. The new species is attributed to Gyrothyris on the basis of (a) morphological and growth trajectory similarities; (b) phylogenetic analyses of an alignment of DNA sequence (similar to 2900-sites) obtained from nuclear-encoded small- and large-subunit ribosomal RNA genes (SSU and LSO; and (c) the presence of a distinctive, two-part deletion in the LSU gene. It is distinguished morphologically from Gyrothyris mawsoni and its subspecies by both internal and external morphology and by its isolated geographical distribution, which extends the patchy, known range of this genus to an area some 2000 km north of its previous northern limit around New Zealand. Phylogenetic analyses of the rDNAs and of mitochondrial cox1 gene sequences (663 sites) confirm previous indications that the New Zealand endemic terebratelloid genera form a clade (Neothyris (Calloria, Gyrothyris, Terebratella), but the position of Terebratella with respect to Calloria and Gyrothyris remains weakly established. These sequences disagree inexplicably about the closeness of the relationship between Neothyris parva and N. lenticidaris. Analyses of the first sequences from Calloria variegata, a species restricted to the Hauraki Gulf, New Zealand, are consistent with the possibility that it originated locally, and recently, from C inconspicua. Magellania venosa from S. America/Falklands joins with Antarctic Magellaninia fragilis and M. joubini to form an rDNA clade that excludes Terebratalia as the putative sister-group of the New Zealand terebratelloid clade. The cox1(but not the rDNA) sequences of the New Zealand clade pass a test for clock-like rates of evolution, and maximum likelihood pairwise distances suggest that if genetic isolation between the ancestor of Antarctic Magellania and the last common ancestor of the New Zealand terebratelloid clade was initiated by separation of the Antarctic and New Zealand plates similar to 90 Mya, isolation from M. venosa was initiated earlier, perhaps similar to 145 Mya. However, in the simple phylogenctic reconstruction presented here from cox1 sequences, S. American and Antarctic Magellania spp. do not yield a well-supported clade, perhaps because of differences in base composition.

Résumé [+]
[-]
The Glypheidea is a group of lobster-like decapods that appeared in the Triassic and that was thought to be extinct until 1975, when a specimen of the species Neoglyphea inopinata was caught off the Philippines. More recently, in 2005, a specimen of another glypheid species, Laurentaeglyphea neocaledonica, was discovered near New Caledonia. Here, we construct a decapod molecular data set including the two extant glypheid species sequenced from eight nuclear and mitochondrial genes. Our study strongly shows that the two extant genera of glypheids cluster together, and further confirms the status of Glypheidea as a separate infraorder. Moreover the reptantian decapods are divided into two major groups, one including Brachyura, Anomura, and Axiidea, and the other including Astacidea, Polychelida, Achelata, and Glypheidea. Although commonly nicknamed 'Jurassic shrimps' and considered as 'living fossils', glypheids are therefore a derived decapod lineage. (C) 2010 Academie des sciences. Published by Elsevier Masson SAS.

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.

Systematic Biology 63(4): 457-479. DOI:10.1093/sysbio/syu008
Résumé [+]
[-]
Lobsters are a ubiquitous and economically important group of decapod crustaceans that include the infraorders
Polychelida, Glypheidea, Astacidea andAchelata. They include familiar forms such as the spiny, slipper, clawed lobsters and crayfish and unfamiliar forms such as the deep-sea and “living fossil” species. The high degree of morphological diversity among these infraorders has led to a dynamic classification and conflicting hypotheses of evolutionary relationships. In this study, we estimated phylogenetic relationships among the major groups of all lobster families and 94% of the genera using six genes (mitochondrial and nuclear) and 195 morphological characters across 173 species of lobsters for the most comprehensive sampling to date. Lobsters were recovered as a non-monophyletic assemblage in the combined (molecular + morphology) analysis. All families were monophyletic, with the exception of Cambaridae, and 7 of 79 generawere recovered as poly- or paraphyletic. A rich fossil history coupled with dense taxon coverage allowed us to estimate and compare divergence times and origins of major lineages using two drastically different approaches. Age priors were constructed and/or included based on fossil age information or fossil discovery, age, and extant species count data. Results from the two approaches were largely congruent across deep to shallow taxonomic divergences across major lineages. The origin of the first lobster-like decapod (Polychelida) was estimated in the Devonian (∼409–372 Ma) with all infraorders present in the Carboniferous (∼353–318 Ma). Fossil calibration subsampling studies examined the influence of sampling density (number of fossils) and placement (deep, middle, and shallow) on divergence time estimates. Results fromour study suggest including at least 1 fossil per 10 operational taxonomic units (OTUs) in divergence dating analyses.

Résumé [+]
[-]
The genus Paramunida belongs to the family Galatheidae, one of the most species rich families among anomuran decapod crustaceans. In spite of the genus has received substantial taxonomic attention, subtle morphological variations observed in numerous samples suggest the existence of undescribed species. The examination of many specimens collected during recent expeditions and morphological and molecular comparisons with previously described species have revelaled the existence of eleven new lineages. All of them are distinguished by subtle and constant morphological differences, which are in agreement with molecular divergences reported for the mitochondrial markers ND1 and 16S rRNA. Here, we describe and illustrate the new species, providing brief redescriptions for the previously known species, and a dichotomous identification key for all species in the genus.

Résumé [+]
[-]
The diversification of Indo-Pacific marine fauna has long captivated the attention of evolutionary biologists. Previous studies have mainly focused on coral reef or shallow water-associated taxa. Here, we present the first attempt to reconstruct the evolutionary historyphylogeny, diversification, and biogeographyof a deep-water lineage. We sequenced the molecular markers 16S, COI, ND1, 18S, and 28S for nearly 80% of the nominal species of the squat lobster genus Paramunida. Analyses of the molecular phylogeny revealed an accelerated diversification in the late OligoceneMiocene followed by a slowdown in the rate of lineage accumulation over time. A parametric biogeographical reconstruction showed the importance of the southwest Pacific area, specifically the island arc of Fiji, Tonga, Vanuatu, Wallis, and Futuna, for diversification of squat lobsters, probably associated with the global warming, high tectonic activity, and changes in oceanic currents that took place in this region during the OligoceneMiocene period. These results add strong evidence to the hypothesis that the Neogene was a period of major diversification for marine organisms in both shallow and deep waters.

Résumé [+]
[-]
The seamounts chain offers a set of fragmented habitats in which species with poor dispersive ability may undergo divergence in allopatry. Such a scenario may explain the endemism often described on seamounts. In gastropods, it is possible to infer the mode of development of a species from the morphology of its larval shell. Accordingly, we examine the population genetics of several caenogastropods from the Norfolk and Lord Howe seamounts (south-west Pacific) with contrasting modes of larval development. A prerequisite to our study was to clarify the taxonomic framework. The species delimitation was ruled using an integrative approach, based on both morphological and molecular evidence. Molecular data indicate an unexpected taxonomic diversity within the existing species names. Both the clarification of the taxonomic framework and the importance of the sampling effort allow us to confidently detect cryptic diversity and micro-endemism. These results are discussed in relation to the dispersive capacities of the organisms. (C) 2010 The Linnean Society of London, Biological Journal of the Linnean Society, 2010, 100, 420-438.

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

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

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.

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 [+]
[-]
Two new species belonging to the family Goneplacidae MacLeay, 1838 (Crustacea, Decapoda, Brachyura) are described from the western Pacific Ocean. The first belongs to Carcinoplax H. Milne Edwards, 1852, the second to Pycnoplax Castro, 2007. The new species of Corcinoplax is distinguished from the 18 known species of the genus by the morphologies of the first male pleopods and outer orbital and anterolateral teeth; the new species of Pycnoplax is distinguished from the five known species of the genus by the morphology of the first and second male pleopods and the granular carapace. A female specimen of a third goneplacid, Thyraplax truncata Castro, 2007, which was previously known only from male specimens, is also described. The characters of the two new species further confirm that in the Goneplacidae s.s. the morphology of the external reproductive structures rather than that of the carapace are far more reliable in showing phylogenetic relationships among supraspecific taxa.

Zootaxa 3866(2): 261-276. DOI:10.11646/zootaxa.3866.2.5
Résumé [+]
[-]
The present study describes a new species of Arcoscalpellum Hoek, 1907, and a new species of Gymnoscalpellum Newman & Ross, 1971, collected by deep-sea expeditions led by the Muséum national d’Histoire naturelle (Paris) in the Coral Sea off New Caledonia, Papua New Guinea (PNG), the Solomon Islands and Vanuatu. Arcoscalpellum epeeum sp. Nov. Differs from all described species of Arcoscalpellum by the presence of a long, sharp, sword-shaped carina, which extends beyond the apices of the terga by 1/3 to 1/4 of their length. The species is dioecious, with large females and dwarf males that are sac-like, lack shell plates and are housed in paired receptacles at the inner edges of the scutal plates. Arcoscalpellum epeeum sp. Nov. Was collected in the waters of New Caledonia and Vanuatu. Gymnoscalpellum indopacificum sp. Nov. Differs from the six currently described species of Gymnoscalpellum by having a very small inframedian latus and a branched upper latus. The species is dioecious, with large females and dwarf males, the latter composed of 4 shell plates and housed in paired receptacles at the inner edges of the scutal plates. The penis of the dwarf males of G. indopacificum sp. Nov. Is about 0.8 of the total length of the male and has five side branches extending out along its length. Gymnoscalpellum indopacificum sp. Nov. Is distributed in the waters of Papua New Guinea, the Solomon Islands and Vanuatu, and represents the first record of this genus in the Indo-Pacific region.

Mémoires du Muséum national d'Histoire naturelle 204:191-230, ISBN:978-2-85653-692-6
Résumé [+]
[-]
Recent French deep-sea expeditions in the Indo-West Pacific resulted in the collection of abundant material of the deep-sea lobster genus Puerulus Ortmann, 1897 (Palinuridae). Difficulties in identification necessitated a generic revision and as a result, five new species are described, all of which are similar to P. angulatus (Bate, 1888). Puerulus angulatus was thought to have a wide distribution from eastern Africa to Marquesas Islands, but is now restricted to the western Pacific, from Japan to Australia. Of the five new species, P. gibbosus n. sp. is found in eastern Africa, P. mesodontus n. sp. from Japan to Fiji, P. richeri n. sp. from the New Caledonia to Marquesas Islands, while P. sericus n. sp. and P. quadridentis n. sp. mainly occur around New Caledonia. Of the other three previously described species, the distribution of P. velutinus Holthuis, 1963, is extended to Fiji, while P. sewelli Ramadan, 1938, and P. carinatus Borradaile, 1910, are still only known from the northern and western parts of the Indian Ocean, respectively. COI gene sequence differences support the morphological species distinctions.

Résumé [+]
[-]
The Oxfordian fauna from the Terrain à Chailles Formation, eastern France (Haute- Saône, Franche-Comté) is remarkable for its exceptionally preserved crustaceans found in siliceous concretions locally named “chailles”. The crustacean fauna includes 9 different species assigned to the Glypheidae, the Erymidae, the Eryonidae and the Axiidae. Glypheid and erymid lobsters are the most diversified groups with four and three different species respectively. Re-examination of numerous new specimens allows to a more modern and more complete characterization of Glyphea regleyana (Desmarest, 1822), Glyphea muensteri von Meyer, 1840 and Eryma ventrosa (von Meyer, 1835). New detailed anatomic descriptions of these species highlight the presence of marked sexual dimorphism in G. regleyana and probably in E. ventrosa. They reveal processes of autotomy and phenomena of ecdysis in G. regleyana, E. ventrosa and G. muensteri. Quantitative analyses based on 424 nodules show three dominant species: 1) Glyphea regleyana (50.5% of nodules); 2) Eryma ventrosa (24.8%); and 3) Glyphea muensteri (16.5%).Convergent lines of evidence from depositional environment, comparisons with others Jurassic crustaceans and modern analogues indicate that the crustacean fauna from the Terrain à Chailles Formation probably inhabited a moderately deep water setting most probably about 100-150 m (lower circalittoral zone) where light intensity was even sensitive. These crustaceans constitute a very original assemblage intermediary between the communities from the shallow carbonate platforms (e.g., Solnhofen) and those from the bathyal zone (e.g., La Voulte). This new set of data sheds new light on the colonization of the distal platforms by crustacean communities in the Mesozoic.

Résumé [+]
[-]
A phylogenetic analysis of a total of 31 species: 27 fossil species from seven families (Glypheidae, Litogastridae, Mecochiridae, Pemphicidae, Erymidae, Clytiopsidae, Chimaerastacidae), and four extant species from three families (Glypheidae, Nephropidae, Stenopodidae) is proposed. Most of the genera considered are coded exclusively based upon their type species and, as much as possible, based upon the type specimens. The cladistic analysis demonstrates that the glypheidean lobsters (infraorder Glypheidea) form a monophyletic group including two superfamilies: Glypheoidea and Pemphicoidea new status. Glypheoidea includes three families: Glypheidae, Mecochiridae and Litogastridae. Litogastridae is the sister group of the clade Glypheidae + Mecochiridae. Pemphicoidea includes a single family: Pemphicidae. A new classification of Glypheidea is proposed and currently known genera are rearranged based upon the phylogenetic analysis.

The infraorder Stenopodidea is a relatively small group of marine decapod crustaceans including the well known cleaner shrimps, but their higher taxonomy has been rather controversial. This study provides the most comprehensive molecular phylogenetic analyses of Stenopodidea using sequence data from two mitochondrial (16S and 12S rRNA) and two nuclear (histone H3 and sodium–potassium ATPase a-subunit (NaK)) genes. We included all 12 nominal genera from the three stenopodidean families in order to test the proposed evolutionary hypothesis and taxonomic scheme of the group. The inferred phylogeny did not support the familial ranking of Macromaxillocarididae and rejected the reciprocal monophyly of Spongicolidae and Stenopididae. The genera Stenopus, Richardina, Spongiocaris, Odontozona, Spongicola and Spongicoloides are showed to be poly- or paraphyletic, with monophyly of only the latter three genera strongly rejected in the analysis. The present results only strongly support the monophyly of Microprosthema and suggest that Paraspongiola should be synonymised with Spongicola. The three remaining genera, Engystenopus, Juxtastenopus and Globospongicola, may need to be expanded to include species from other genera if their statuses are maintained. All findings suggest that the morphological characters currently adopted to define genera are mostly invalid and substantial taxonomic revisions are required. As the intergeneric relationships were largely unresolved in the present attempt, the hypothesis of evolution of deep-sea sponge-associated taxa from shallow-water free-living species could not be verified here. The present molecular phylogeny, nevertheless, provides some support that stenopoididean shrimps colonised the deep sea in multiple circumstances.

Abstract
Whelks in the sister-genera Enigmaticolus and Thermosipho (Gastropoda: Buccinidae) commonly inhabit deep-water hydrothermal vents and hydrocarbon seeps. Thermosipho desbruyeresi, originally described from the Lau Basin, was thought to occur in vents across the western Pacific, with Eosipho desbruyeresi nipponensis described from the Okinawa Trough treated as its junior synonym. However, new material collected from vents in the Okinawa Trough and seeps in the South China Sea exhibit key characteristics of Enigmaticolus. Re-examination of the types revealed that Eosipho d. nipponensis is actually morphologically distinct from Thermosipho desbruyeresi. A molecular phylogeny reconstructed using the cytochrome c oxidase subunit I (COI) gene confirmed the placement of both taxa in Enigmaticolus and supported their distinctiveness at the species level. We, therefore, rehabilitate E. d. nipponensis as Enigmaticolus nipponensis comb. nov. and transfer T. desbruyeresi to the same genus, as Enigmaticolus desbruyeresi comb. nov. Our results also revealed that Enigmaticolus monnieri described from east Africa and E. inflatus described from the South China Sea are in fact conspecific with E. nipponensis. We discuss the distribution and biogeography, as well as morphological variability, of Enigmaticolus in the light of these new findings. Thermosipho is then left with only its type species, T. auzendei from the East Pacific vents. We have revised the diagnosis for the two genera, as well as the species included in them.

The new waspfish Ocosia dorsomaculata n. sp. (Tetrarogidae) is described, based on specimens from Australia (5) and New Caledonia (51). Although O. dorsomaculata and Ocosia apia Poss & Eschmeyer 1975 both share modally XVI, 8 dorsal-fin rays with a long second dorsal-fin spine, and presence of supraocular, lateral lacrimal, and suborbital spines, the former has modally 13 pectoral-fin rays (vs. usually 12 in the latter), a lower modal count of total gill rakers (10 vs. 16–18), greater upper-jaw length, greater third to sixth dorsal-fin spine lengths, the third dorsal-fin spine slightly shorter than the second dorsal-fin spine (vs. third spine markedly shorter than second spine), 1 or 2 prominent pale brown to dark brown blotches on the membrane between the fifth to eighth or sixth to ninth dorsal-fin spines (vs. 1 blotch on the membrane around the third dorsal-fin spine and 1 blotch on the membrane between the sixth to eighth dorsal-fin spines), and body with 11–15 longitudinal pale brown to dark brown bars along lateral line (vs. irregular brown specks). A key to the species of Ocosia is given.

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

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

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

Journal of Zoological Systematics and Evolutionary Research 59(8): 1718-1753. DOI:10.1111/jzs.12512
Résumé [+]
[-]
Recent sampling efforts in the deep seas of southern and eastern Australia have generated a wealth of DNA-suitable material of neogastropods of the family Raphitomidae. Based on this material, a molecular phylogeny of the family has revealed a considerable amount of genus and species level lineages previously unknown to science. These taxa are now the focus of current integrative taxonomic research. As part of this ongoing investigation, this study focuses on the genera Austrobela, Austrotheta (both Criscione, Hallan, Puillandre & Fedosov, 2020), Spergo Dall, 1895 and Theta Clarke, 1959. We subjected a comprehensive mitochondrial DNA dataset of representative deep-sea raphitomids to Automatic Barcode Gap Discovery, which recognized 24 primary species hypotheses (PSHs). Following additional evaluation of shell and radular features, as well as examination of geographic and bathymetric ranges, 18 of these PSHs were converted to secondary species hypotheses (SSHs). Based on the evidence available, the most likely speciation mechanisms involved were evaluated for each pair of sister SSHs, including niche partitioning. Eleven SSHs were recognized as new and their systematic descriptions are provided herein. Of these, four were attributed to Austrobela, one to Austrotheta, four to Spergo and two to Theta. While all new species are endemic to Australian waters, other species studied herein exhibit wide Indo-Pacific distributions, adding to the growing body of evidence suggesting that wide geographic ranges in deep-sea Raphitomidae are more common than previously assumed.

Résumé [+]

Abstract
Although raphitomid snails are a dominant component of gastropod communities in deep seas worldwide, their systematics is still largely tentative. We assembled the most complete sampling of Raphitomidae from south-eastern Australia to date. Based on morphological and molecular data from this material, we produced a robust phylogenetic framework and used it to delimit genera. For the focus area, our results show a large proportion of undescribed species- and genus-level taxa, 11 of which are formally described herein. We demonstrate that the examination of purely morphological characters rarely suffices for the purpose of accurate genus delimitation. As a result, some traditionally highly diverse raphitomid genera (such as Gymnobela) turn out to be artificial assemblages of several unrelated, mostly undescribed, genus-level lineages. Our data suggest that comparable configurations of shell and radular features, observed at the genus level, commonly do not reflect true phylogenetic relationships. However, our results are inconclusive as to whether homoplasy or conservatism are the drivers of this phenomenon. Accommodating for the inevitable sampling biases, south-eastern Australia appears as a possible hotspot for both raphitomid diversity and endemism, when compared with adjacent areas.

In 2005, the EBISCO oceanographic campaign collected numerous large ostracods in the Coral Sea, off southwest New Caledonia. These ostracods belong to a new species, Azygocypridina brynmawria, and differ from the morphologically similar Azygocypridina Iowryi in the color of the soft parts and details of the morphology of the second antenna, furca, and terminal tooth of the seventh limb, as determined by light microscopy and scanning electron rnicroscopy (SEM). Included is a discussion of the unique color and locality of these organisms.

Résumé [+]

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

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

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

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.

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.

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

Fedosov A.E. & Puillandre N. 2012. Phylogeny and taxonomy of the Kermia–Pseudodaphnella (Mollusca: Gastropoda: Raphitomidae) genus complex: a remarkable radiation via diversification of larval development. Systematics and Biodiversity 10(4): 447-477. 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.

Forest J. 2006. Laurentaeglyphea, un nouveau genre pour la seconde espèce actuelle de Glyphéide récemment découverte (Crustacea Décapoda Glypheidae). Comptes Rendus Biologies 329(10): 841-846. DOI:10.1016/j.crvi.2006.08.003
Résumé [+]
[-]
Laurentaeglyphea, a new genus for the second recent species of Glypheid recently discovered. (Crustacea Decapoda Glypheidae). In 1975, a recent member of a large group of Crustacea Decapoda was described as Neoglyphea inopinata Forest & de Saint Laurent, until now only known as fossils and presumed extinct since the Eocene. The only known specimen had been collected in the Philippine waters, in 1908, at a depth of 200 m. During the next years, three oceanographical expeditions gave more adult specimens, allowing complete study of the species. From its morphology, it appeared that the status attributed to glypheids in the past in the classification of Decapoda Crustacea was quite erroneous. This group, until then considered as related to Palinurids (rock lobsters) was in fact much closer to Astacids (lobster, crayfish, etc.). In 1982, N. inopinata was recorded from the other side of Equator, from the Timor Sea. In October 2005, a second living species of glypheid was discovered southwest of New Caledonia. It was named Neoglyphea neocaledonica B. Richer de Forges, 2006. However, important and significant differences set apart the two species, especially the ornamentation of the cephalothorax, the conformation of the cephalic part and the proportions of epistom and thoracic appendages, being much more robust. It seems justified to establish, for the more recently described species, a new genus, Laurentaeglyphea, much closer to fossil forms.

Résumé [+]
[-]
Until recently, the family Glypheidae (Decapoda, Reptantia) was known from fossils only, and consequently presumed extinct for 50 million years. However, in 1975 scientists of the Museum National d'Histoire Naturelle in Paris recognized a Recent specimen as belonging to this family. The specimen had been collected in the Phillippines in 1908 at approx. 200 m depth, and had remained unidentified in the collections of the Smithsonian Institution, Washington, D.C., since. That same year, the species was described as Neoglyphea inopinata Forest & de Saint Laurent, thus testifying the actual persistence of the group in today's marine fauna. Three expeditions in the same region, in 1976, 1980, and 1985, yielded another 20 specimens, all caught alive. The subsequent study of those specimens would indicate that the phylogenetic position assigned to the glypheids until then had, in fact, been erroneous. The same applied to the other mesozoic families included in the superfamily Glypheoidea. The glypheoids had usually been placed next to the Scyllaridae and Eryonidae in the infraorder Palinura, and been considered probable ancestors of part of the remaining Decapoda Reptantia. However, their similarities would come out to result rather from analogous resemblances than from actual morphological affinities. In fact, after comparison of the principal characters of the three groups, we have been able to confirm that the Glypheoidea did not exhibit any true relationship with the two others. In contrast, they proved to be closer to the Astacidae and could, eventually, be ranked with those in the same infraorder. A number of recent publications, largely by palaeontologists and based in part on cladistic as well as molecular analyses, have lately supported this point of view. They completely reject the inclusion of the glypheoids in the Palinura, corroborate their affinities with the Astacidea, and exclude the possibility that they would represent a primitive group from which other Reptantia could have evolved. The lineage of the Glypheoidea most probably appeared in the Permian-Triassic, prospered in the Jurassic, and subsequently declined from the Cretaceous to the Eocene. It is apparent that the group has not become extinct during that era, but has silently persisted, without leaving fossil traces, with at least two representatives in today's living world. Indeed, a second species of glypheid has recently been discovered in the southwestern Pacific. Though described under the name Neoglyphea neocaledonica, it shows such differences with N. inopinata that I have established a new genus for this species, Laurentaeglyphea, which is even closer to the glypheids known from the Mesozoic and the Eocene.

Résumé [+]
[-]
In the present paper we describe the new genus Amiantofusus gen. nov. to accommodate the Atlantic species Fusus amiantus Dall, 1889. The genus belongs to Fasciolariidae and this family is confirmed as distinct from Buccinidae, based on anatomical differences. We add an Indo-West Pacific fauna of seven species described as new to science: miantofusus pacificus sp. nov. (North Fiji Basin, New Caledonia, southern Coral Sea, south West Pacific), A. gloriabundus sp. nov. (North Fiji Basin, Vitiaz Zone), A. sebalis sp. nov. (New Caledonia, Loyalty Islands, Vanuatu), A. candoris sp. nov. (Chesterfield Islands, Fairway), A. maestratii sp. nov. (New Caledonia), A. borbonica sp. nov. (Reunion) and A. cartilago sp. nov. (Mozambique Channel). In addition we add two unnamed species: A. species 1 (North Fiji Basin) and A. species 2 (Vanuatu). Fusus thielei Schepman, 1911 is briefly discussed, the generic placement is still uncertain.

The tropical deep-water Cominellinae commonly assigned to the genera Manaria E. A. Smith, 1906 and Eosipho Thiele, 1929 are revised. While the taxonomic details at the generic level were discussed by Kantor et al. (2013), the species level is discussed here. Twentyone new species are described: Manaria astrolabis n. sp. (French Polynesia), M. borbonica n. sp. (Réunion), M. circumsonaxa n. sp. (Papua New Guinea and the Solomons), M. corindoni n. sp. (Indonesia), M. corporosis n. sp. (the Solomons, Vanuatu, Coral Sea and New Caledonia), M. explicibilis n. sp. (Papua New Guinea and the Solomons), M. excalibur n. sp. (Indonesia and Western Australia), M. fluentisona n. sp. (the Solomons, Fiji, Wallis and Tonga), M. hadorni n. sp. (Papua New Guinea and New Caledonia), M. indomaris n. sp. (India), M. loculosa n. sp. (Fiji), M. lozoueti n. sp. (North Fiji Basin), M. terryni n. sp. (Mozambique Channel), M. tongaensis n. sp. (Tonga), M. tyrotarichoides n. sp. (Mozambique Channel), Calagrassor bacciballus n. sp. (Philippines), C. delicatus n. sp. (New Zealand), C. hespericus n. sp. (Mozambique), C. pidginoides n. sp. (Philippines, Papua New Guinea, the Solomons and Vanuatu), Enigmaticolus marshalli n. sp. (Kermadec Ridge, Monowai Caldera), and E. voluptarius n. sp. (New Caledonia). Considerable range extensions are recorded: Manaria kuroharai Azuma, 1960 is recorded from the Solomons, New Caledonia, Vanuatu and Tonga; M. brevicaudata (Schepman, 1911) is recorded from Taiwan, the Philippines, the Solomons and Fiji; and Calagrassor poppei (Fraussen, 2001) is recorded from Indonesia and the Solomons. Lathyrus jonkeri Koperberg, 1931, a fossil described from Indonesia, is recorded from the Recent fauna of Indonesia, Philippines and Fiji and is redescribed and placed in Manaria. Sipho jonkeri Koperberg, 1931, another fossil described from Indonesia in the same work, is a secondary homonym of Manaria jonkeri (Koperberg, 1931) and is renamed Manaria koperbergae nom. nov.

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

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

Résumé [+]
[-]
The olive shells of the genus Amalda comprises readily recognized species of marine neogastropod mollusks found around the world. The New Zealand Amalda fauna has particular notoriety as providing one of the best demonstrations of evolutionary morphological stasis, a prerequisite for punctuated equilibrium theory. An excellent fossil record includes representation of three extant endemic Amalda species used to explore patterns of form change. However, the phylogenetic relationship of the New Zealand Amalda species and the timing of their lineage splitting have not been studied, even though these would provide valuable evidence to test predictions of punctuated equilibrium. Here, we use entire mitogenome and long nuclear rRNA gene cassette data from 11 Amalda species, selected from New Zealand and around the world in light of high rates of endemicity among extant and fossil Amalda. Our inferred phylogenies do not refute the hypothesis that New Zealand Amalda are a natural monophyletic group and therefore an appropriate example of morphological stasis. Furthermore, estimates of the timing of cladogenesis from the molecular data for the New Zealand group are compatible with the fossil record for extant species and consistent with expectations of punctuated equilibrium.

Deep Sea Research Part I: Oceanographic Research Papers 64: 86-103. DOI:10.1016/j.dsr.2012.02.002
Résumé [+]
[-]
The increasing number of bathymodiolin mussel species being described from deep-sea chemosynthetic environments worldwide has raised many questions about their evolutionary history, and their systematics is still being debated. Mussels are also abundant in fossil chemosynthetic assemblages, but their identification is problematic due to conservative shell morphology within the group and preservation issues. Potential resolution of bathymodiolin taxonomy requires new character sets, including morphological features that are likely to be preserved in fossil specimens.

Résumé [+]
[-]
The deep-sea malacofauna of temperate Australia remains comparatively poorly known. However, a recent influx of DNA-suitable material obtained from a series of deep-sea cruises has facilitated integrative taxonomic study on the Conoidea (Caenogastropoda : Neogastropoda). Building on a recent molecular phylogeny of the conoidean family Raphitomidae, this study focussed on the genera Gladiobela and Pagodibela (both Criscione, Hallan, Puillandre & Fedosov, 2020). We subjected a representative mtDNA cox1 dataset of deep-sea raphitomids to ABGD, which recognised 14 primary species hypotheses (PSHs), 9 of which were converted to secondary species hypotheses (SSHs). Following the additional examination of the shell and hypodermic radula features, as well as consideration of bathymetric and geographic data, seven of these SSHs were recognised as new to science and given full species rank. Subsequently, systematic descriptions are provided herein. Of these, five are attributed to Gladiobela (three of which are endemic to Australia and two more widely distributed) and two are placed in Pagodibela (one endemic to southern Australia and one widespread in the Pacific). The rarity of many ‘turrids’ reported in previous studies is confirmed herein, as particularly indicated by highly disjunct geographic records for two taxa. Additionally, several of the studied taxa exhibit wide Indo-Pacific distributions, suggesting that wide geographic ranges in deep-sea ‘turrids’ may be more common than previously assumed. Finally, impediments to deep-sea ‘turrid’ taxonomy in light of such comparative rarity and unexpectedly wide distributions are discussed.

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

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

Résumé [+]
[-]
The recent genetic analysis of the muricid subfamily Ergalataxinae has led to a better understanding of this subfamily, but some species were left without appropriate generic assignments and the classification of others required revision. This knowledge gap is partially filled herein, with new combinations and the description of three new genera. The examination of new material, along with a careful re-examination of and comparison to existing material, resulted also in the identification of nine new species. These new genera and new species are described herein, lectotypes are designated and new combinations are given. The geographical range of all the new species is provided on maps. All new species are compared with related or similar species. The radula of Morula palmeri Powell, 1967 is illustrated for the first time.

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

Résumé [+]
[-]
A unique radular configuration for Conoidea, consisting of five teeth in a transverse row (acuspate platelike central and laterals, and duplex marginal teeth), was found in three species previously described in the genus Clavatula: C. delphinae, C. pseudomystica and C. christianae. Analysis of the COI gene demonstrated that they belong to the family Clavatulidae. Paraclavatula n. gen. is described. No similar radulae have been found previously among Conoidea and their morphology suggests that the presence of well-defined lateral teeth is more broadly distributed within Conoidea than previously anticipated. Based on radular morphology alone, it would not be possible to attribute the genus to any presently recognized family of Conoidea.

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

Résumé [+]
[-]
The 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.

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.

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.

Kantor Y.I., Fedosov A.E., Snyder M.A. & Bouchet P. 2018. Pseudolatirus Bellardi, 1884 revisited, with the description of two new genera and five new species (Neogastropoda: Fasciolariidae). European Journal of Taxonomy 433: 1-57. DOI:10.5852/ejt.2018.433
Résumé [+]
[-]
The genus Pseudolatirus Bellardi, 1884, with the Miocene type species Fusus bilineatus Hörnes, 1853, has been used for 13 Miocene to Early Pleistocene fossil species and eight Recent species and has traditionally been placed in the fasciolariid subfamily Peristerniinae Tryon, 1880. Although the fossil species are apparently peristerniines, the Recent species were in their majority suspected to be most closely related to Granulifusus Kuroda & Habe, 1954 in the subfamily Fusininae Wrigley, 1927. Their close affinity was confirmed by the molecular phylogenetic analysis of Couto et al. (2016). In the molecular phylogenetic section we present a more detailed analysis of the relationships of 10 Recent Pseudolatirus-like species, erect two new fusinine genera, Okutanius gen. nov. (type species Fusolatirus kuroseanus Okutani, 1975) and Vermeijius gen. nov. (type species Pseudolatirus pallidus Kuroda & Habe, 1961). Five species are described as new for science, three of them are based on sequenced specimens (Granulifusus annae sp. nov., G. norfolkensis sp. nov., Okutanius ellenae gen. et sp. nov.) and two (G. tatianae sp. nov., G. guidoi sp. nov.) are attributed to Granulifusus on the basis of conchological similarities to sequenced species. New data on radular morphology is presented for examined species.

Kantor Y.I., Castelin M., Fedosov A. & Bouchet P. 2020. The Indo-Pacific Amalda (Neogastropoda, Olivoidea, Ancillariidae) revisited with molecular data, with special emphasis on New Caledonia. European Journal of Taxonomy 706: 1-52. DOI:10.5852/ejt.2020.706
Résumé [+]
[-]
In the ancillariid genus Amalda, the shell is character rich and 96 described species are currently treated as valid. Based on shell morphology, several subspecies have been recognized within Amalda hilgendorfi, with a combined range extending at depths of 150–750 m from Japan to the South-West Pacific. A molecular analysis of 78 specimens from throughout this range shows both a weak geographical structuring and evidence of gene flow at the regional scale. We conclude that recognition of subspecies (richeri Kilburn & Bouchet, 1988, herlaari van Pel, 1989, and vezzaroi Cossignani, 2015) within A. hilgendorfi is not justified. By contrast, hilgendorfi-like specimens from the Mozambique Channel and New Caledonia are molecularly segregated, and so are here described as new, as Amalda miriky sp. nov. and A. cacao sp. nov., respectively. The New Caledonia Amalda montrouzieri complex is shown to include at least three molecularly separable species, including A. allaryi and A. alabaster sp. nov. Molecular data also confirm the validity of the New Caledonia endemics Amalda aureomarginata, A. fuscolingua, A. bellonarum, and A. coriolis. The existence of narrow range endemics suggests that the species limits of Amalda with broad distributions, extending, e.g., from Japan to Taiwan (A. hinomotoensis) or even Indonesia, the Strait of Malacca, Vietnam and the China Sea (A. mamillata) should be taken with caution.

Kantor Y.I. & Puillandre N. 2021. Rare, deep-water and similar: revision of Sibogasyrinx (Conoidea: Cochlespiridae). European Journal of Taxonomy 773: 19-60. DOI:10.5852/ejt.2021.773.1509
Résumé [+]
[-]
The genus Sibogasyrinx has to date included only four species of rare deep-water Conoidea, each known from few specimens. In shell characters it strongly resembles three distantly-related genera, two of which, Comitas and Leucosyrinx, belong to a different family, the Pseudomelatomidae. A molecular phylogenetic analysis of a large amount of material of Conoidea has revealed the existence of much additional undescribed diversity within Sibogasyrinx from the central Indo-Pacific and temperate Northern Pacific. Based on partial sequences of the mitochondrial cox1 gene and morphological characters of 54 specimens, 10 species hypotheses are proposed, of which six are described as new species: S. subula sp. nov., S. lolae sp. nov., S. maximei sp. nov., S. clausura sp. nov., S. pagodiformis sp. nov. and S. elbakyanae Kantor, Puillandre & Bouchet sp. nov. One of the previously described species was absent in our material. Most of the new species are very similar and are compared to Leucosyrinx spp. Species of Sibogasyrinx are unique among Conoidea on account of the high intrageneric variability in radular morphology. Three distinct radula types are found within Sibogasyrinx, two of which are confined to highly supported subclades.

Lemaitre R. 2013. The genus Paragiopagurus Lemaitre, 1996 (Crustacea, Decapoda, Anomura, Paguroidea, Parapaguridae): A worldwide review and summary, with descriptions of five new species, in Ahyong S.T., Chan T.Y., Corbari L. & Ng P.K.(Eds), Tropical Deep-Sea Benthos 27. Mémoires du Muséum national d'Histoire naturelle 204:311-421, ISBN:978-2-85653-692-6
Résumé [+]
[-]
A review of the deep-water hermit crab species of the genus Paragiopagurus Lemaitre, 1996 from the world oceans is presented. The core specimen base for this study has come primarily from the abundant collections of species of this genus obtained during French campaigns over the last four decades, and complemented with numerous specimens from many other deep-sea expeditions and deposited in various museum holdings around the world. Paragiopagurus is one of the most speciose genus among the Parapaguridae Smith, 1882, although it is considered a phylogenetically heterogeneous assemblage and does not appear to have an apomorphy of its own. Bathymetrically, the species range in depth from 36 to 2034 m, although they occur most frequently between 200 and 1000 m. The species utilize as housing, gastropod shells (or rarely scaphopod shells, siliceous sponges, or hollow pieces of wood) that may or may not be colonized by actinians or zoanthids. In this review, 24 species are recognized, of which five are new, P. laperousei n. sp., P. orthotenes n. sp., P. oxychelos n. sp., P. trilineatus n. sp., and P. umbonatus n. sp. The new species are fully described and illustrated. All previously known species of the genus are diagnosed or redescribed, and previously published illustrations of important taxonomic characters assembled and complemented, when useful, with new illustrations. The treatment of each species includes a full synonymy, materials examined (type and non-types), colouration, habitat or type of housing used, distribution, and remarks on taxonomy and morphological affinities. Colour photographs are included for 14 of the species. Parapagurus curvispina de Saint Laurent, 1974, a species tentatively moved after its description to Sympagurus Smith, 1883 and then to Paragiopagurus, is herein transferred with certainty to Oncopagurus
Lemaitre, 1996. Parapagurus spinimanus Balss, 1911, a species that had been incorrectly placed in Paragiopagurus, is herein moved to Sympagurus. Parapagurus sculptochela Zarenkov, 1990, a taxon previously considered a junior synonym of Paragiopagurus boletifer (de Saint Laurent, 1972), is herein resurrected as a valid species of Paragiopagurus. The bathymetric and geographic distributions of Paragiopagurus species are summarized and briefly discussed, including a summary table, graph, and map with generalized distribution patterns.

Lemaitre R. 2014. A worldwide taxonomic and distributional synthesis of the genus Oncopagurus Lemaitre, 1996 (Crustacea: Decapoda: Anomura: Parapaguridae), with descriptions of nine new species. The Raffles Bulletin of Zoology 62: 210–301
Résumé [+]
[-]
A worldwide taxonomic and distributional synthesis of the deep-water hermit crab genus Oncopagurus
Lemaitre, 1996 is presented. This genus, originally defined for 10 species is set apart from other Parapaguridae as well as other Paguroidea, by one synapomorphy: the presence of an upwardly curved epistomial spine. This study is based on a large amount of specimens deposited in major museums and collected during deep-sea sampling across the world oceans since the late 1800s, with the bulk of material coming from French campaigns in the Indo-Pacific, central and south Pacific during the last 40 years. A total of 24 species are recognised in this investigation, nine of which are new and fully described and illustrated. All previously known species are diagnosed or re-described, including figures assembled from recent published accounts or newly illustrated, of the most important morphological features useful for identifi cations. Information for each species includes a synonymy (full or abbreviated if a synonymy has recently been published), material examined (type and non-types), variations when signifi cant, colouration when available, habitat or type of housing used, distribution, and remarks on taxonomy and morphological affinities. Rare colour photographs are included for five species. Species of Oncopagurus range in depth from the Continental Shelf (50 m) to the Continental Rise (2308 m), although they are most commonly found in 50–500 m. Individuals of the majority of species in this genus are minute in size (< 3 mm in shield length), species differ in subtle morphological characters, and often exhibit the same broad morphological variations related to sex and size that has been documented in species of other genera of Parapaguridae. Oncopagurus mironovi Zhadan, 1997, a taxon reported from the Nazca and Sala-y-Gómez Ridges, is considered a junior synonym of the widely distributed O. indicus (Alcock, 1905). The bathymetric and geographic distributions of Oncopagurus species are summarised and briefly discussed, complemented with a summary table, graph, and map with generalised distribution patterns. The scant phylogenetic knowledge of this genus is summarised.

Lemaitre R., Rahayu D.L. & Komai T. 2018. A revision of “blanket-hermit crabs” of the genus Paguropsis Henderson, 1888, with the description of a new genus and five new species (Crustacea, Anomura, Diogenidae). ZooKeys 752: 17-97. DOI:10.3897/zookeys.752.23712
Résumé [+]
[-]
For 130 years the diogenid genus Paguropsis Henderson, 1888 was considered monotypic for an unusual species, P. typica Henderson, 1888, described from the Philippines and seldom reported since. Although scantly studied, this species is known to live in striking symbiosis with a colonial sea anemone that the hermit can stretch back and forth like a blanket over its cephalic shield and part of cephalothoracic appendages, and thus the common name “blanket-crab”. During a study of paguroid collections obtained during recent French-sponsored biodiversity campaigns in the Indo-West Pacific, numerous specimens assignable to Paguropsis were encountered. Analysis and comparison with types and other historical specimens deposited in various museums revealed the existence of five undescribed species. Discovery of these new species, together with the observation of anatomical characters previously undocumented or poorly described, including coloration, required a revision of the genus Paguropsis. The name Chlaenopagurus andersoni Alcock & McArdle, 1901, considered by Alcock (1905) a junior synonym of P. typica, proved to be a valid species and is resurrected as P. andersoni (Alcock, 1899). In two of the new species, the shape of the gills, length/width of exopod of maxilliped 3, width and shape of sternite XI (of pereopods 3), and armature of the dactyls and fixed fingers of the chelate pereopods 4, were found to be characters so markedly different from P. typica and other species discovered that a new genus for them, Paguropsina gen. n., is justified. As result, the genus Paguropsis is found to contain five species: P. typica, P. andersoni, P. confusa sp. n., P. gigas sp. n., and P. lacinia sp. n. Herein, Paguropsina gen. n., is proposed and diagnosed for two new species, P. pistillata gen. et sp. n., and P. inermis gen. et sp. n.; Paguropsis is redefined, P. typica and its previously believed junior synonym, P. andersoni, are redescribed. All species are illustrated, and color photographs provided. Also included are a summary of the biogeography of the two genera and all species; remarks on the significance of the unusual morphology; and remarks on knowledge of the symbiotic anemones used by the species. To complement the morphological descriptions and assist in future population and phylogenetic investigations, molecular data for mitochondrial COI barcode region and partial sequences of 12S and 16S rRNA are reported. A preliminary phylogenetic analysis using molecular data distinctly shows support for the separation of the species into two clades, one with all five species of Paguropsis, and another with the two species Paguropsina gen. n.

Résumé [+]
[-]
Recent advancements in deep-sea expeditions have made possible to sample adequate quantities of deep-sea organisms over wide geographical ranges for population genetic studies. Scalpellum stearnsii is a common stalked barnacle that occurs in the mesobenthic environment (>200 m depth) throughout the West Pacific Ocean and covers several major deep-sea basins. The present study examined the diversity and genetic differentiation of S. stearnsii populations from the East China Sea, West Philippine Basin, Sulu Sea, and Caroline Trenches. Mo lecular analyses based on partial sequences of the mitochondrial gene COI and nuclear gene H3 revealed four distinct clades of S. stearnsii—SS, CF1, CF2, and CF3—with distinct species-level pairwise divergences among the clades. SS (representing S. stearnsii, based on morphological comparison with holotype) is mainly present in the East China Sea and the Philippine Basin, CF1 is present in the East China Sea, CF2 is present in the Sulu Sea, and CF3 is exclusively present in the Caroline Trench (Southwest Pacific Ocean). Deep genetic differentiation be tween the northern (SS and CF1) and southern clades (CF2 and CF3) was estimated to have occurred around 33 million years ago, and the eastward-flowing Equatorial Undercurrent (100–200 m) and oxygen minimum zone (300–400 m) are the putative barriers to gene flow. The timing is concordant with reported diversification events in both shallow- and deep-water organisms during the Oligocene and Miocene periods. This cross-ocean, -taxon, and -habitat divergence time suggests speciation driven by global-scale events. Recent size expansion likely occurred in all the four clades and subsequent populations, predating the Last Glacial Maximum (LGM). The persistence of mesobenthic deep-sea barnacles through the temperature fluctuation at the LGM can be a common pattern.

Résumé [+]
[-]
Bathymodiolinae mussels have been used as a biological model to better understand the evolutionary origin of faunas associated with deep-sea hydrothermal vents and cold seeps. Most studies to date, however, have sampled with a strong bias towards vent and seep species, mainly because of a lack of knowledge of closely related species from organic falls. Here we reassess the species diversity of deep-sea mussels using two genes and a large taxon sample from the South-Western Pacific. This new taxonomic framework serves as a basis for a phylogenetic investigation of their evolutionary history. We first highlight an unexpected allopatric pattern and suggest that mussels usually reported from organic falls are in fact poorly specialized with regard to their environment. This challenges the adaptive scenarios proposed to explain the diversification of the group. Second, we confirm that deep-sea mussels arose from organic falls and then colonized hydrothermal vents and cold seeps in multiple events. Overall, this study constitutes a new basis for further phylogenetic investigations and a global systematic revision of deep-sea mussels. (C) 2010 Elsevier Inc. All rights reserved.

Résumé [+]
[-]
Adaptive radiations present fascinating opportunities for studying the evolutionary process. Most cases come from isolated lakes or islands, where unoccupied ecological space is filled through novel adaptations. Here, we describe an unusual example of an adaptive radiation: symbiotic mussels that colonized island-like chemosynthetic environments such as hydrothermal vents, cold seeps and sunken organic substrates on the vast deep-sea floor. Our time-calibrated molecular phylogeny suggests that the group originated and acquired sulfur-oxidizing symbionts in the Late Cretaceous, possibly while inhabiting organic substrates and long before its major radiation in the Middle Eocene to Early Oligocene. The first appearance of intracellular and methanotrophic symbionts was detected only after this major radiation. Thus, contrary to expectations, the major radiation may have not been triggered by the evolution of novel types of symbioses. We hypothesize that environmental factors, such as increased habitat availability and/or increased dispersal capabilities, sparked the radiation. Intracellular and methanotrophic symbionts were acquired in several independent lineages and marked the onset of a secondwave of diversification at vents and seeps. Changes in habitat type resulted in adaptive trends in shell lengths (related to the availability of space and energy, and physiological trade-offs) and in the successive colonization of greater water depths.

Luque Á.A., Geiger D.L. & Rolán E. 2011. A revision of the genus Satondella Bandel, 1998 (Gastropoda, Scissurellidae). Molluscan Research 31(1): 1-14
Résumé [+]
[-]
This revision of the scissurellid genus Satondella Bandel, 1998 is mainly based on shell characters due to the availability of only a few live collected specimens. There are seven Recent species (two described as new) and one Eocene fossil. Satondella minuta Bandel, 1998, the type species from Indonesia, is redescribed and its range extended to New Caledonia, Solomon and Fiji Islands. Satondella tabulata (Watson, 1886) is only known from type material off Culebra Island (Puerto Rico); lectotype and paralectotypes are here designated, and similar material from the Indo-Pacific is discussed. Satondella brasiliensis (Mattar, 1987) is another W. Atlantic species, ranging from Bermuda to Brazil. Satondella senni (Geiger, 2003) is only known from the E. Pacific (Easter Island) and Satondella danieli Segers, Swinnen & Abreu, 2009 from the NE. Atlantic Ocean (Desertas and Madeira Islands). The two new species are distributed through the E. Indian and W. Pacific oceans (S. cachoi n. sp.) and W. Pacific (S. dantarti n. sp.). The Tongan Eocene fossil S. kondoi (Ladd, 1970) is redescribed and illustrated with SEM images. Satondella brasiliensis and S. cachoi have a typical scissurellid radula, except for uniquely having one cusp on the inner edge of the third lateral. The monophyly of the genus is discussed, since species currently included in Satondella show two clearly different shell patterns but all share the unique chimney-like foramen.

Résumé [+]
[-]
We analyzed the distribution patterns of the galatheid squat lobsters (Crustacea, Decapoda, Galatheidae) of the Pacific Ocean. We used the presence/absence data of 402 species along the continental slope and continental rise (200-2000 m) obtained from 54 cruises carried out in areas around the Philippines, Indonesia, Solomon, Vanuatu, New Caledonia, Fiji, Tonga, Wallis and Futuna and French Polynesia. The total number of stations was ca. 3200. We also used published data from other expeditions carried out in the Pacific waters, and from an exhaustive search of ca. 600 papers on the taxonomy and biogeography of Pacific species. We studied the existence of biogeographic provinces using multivariate analyses, and present data on latitudinal and longitudinal patterns of species richness, rate of endemism and the relationship between body sizes with the size of the geographic ranges. Latitudinal species richness along the Western and Eastern Pacific exhibited an increase from higher latitudes towards the Equator. Longitudinal species richness decreased considerably from the Western to the Central Pacific. Size frequency distribution for body size was strongly shifted toward small sizes and endemic species were significantly smaller than non-endemics. This study concludes that a clear separation exists between the moderately poor galatheid fauna of the Eastern Pacific and the rich Western and Central Pacific faunas. Our results also show that the highest numbers of squat lobsters are found in the Coral Sea (Solomon-Vanuatu-New Caledonia islands) and Indo-Malay-Philippines archipelago (IMPA). The distribution of endemism along the Pacific Ocean indicates that there are several major centres of diversity, e.g. Coral Sea, IMPA, New Zealand and French Polynesia. The high proportion of endemism in these areas suggests that they have evolved independently. (C) 2009 Elsevier Ltd. All rights reserved.

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.

More than 5000 specimens of squat lobsters belonging to the families Munididae and Munidopsidae were collected during four cruises
along the coasts of Papua New Guinea. The study of these specimens revealed the presence of 13 new species (one Babamunida, one Crosnierita, eight Munida, one Paramunida and two Munidopsis). Overall, 109 species of Munididae and 37 of Munidopsidae are recognized.
We include the records of all species, describing and illustrating the new species. Furthermore, we provide some new data on the colour patterns for some species. We have also included molecular data from two mitochondrial markers (16S rRNA and COI) to support the taxonomic status of different new species.

Résumé [+]
[-]
The discovery of 11 Nautilus macromphalus shells in marine environments near New Caledonia constitutes the first opportunity for taphonomic analysis of empty shells of unburied, externally shelled cephalopods on the seafloor. Radiometric dating indicates specimen ages range from 14 to 42 years. These modern specimens provide a unique opportunity to examine the early, preburial taphonomy of this group of animals including shell condition, radiometric-age dating, epizoan encrustation, color degradation, and sediment infilling. The following conclusions are made:
(1) given the limited sample available for study and assuming equal conditions where shells rested on the seafloor, the length of time the shell
is unburied will not control the degree of epizoan encrustation or the external shell appearance; (2) shell boring is a major destructive process that probably impacts the potential of the shells to become fossilized; and (3) shells in the photic zone are impacted differently than those dredged from a deep water environment below the photic zone. A major part of this difference is probably the result of both boring and encrusting organisms, especially algae. By comparison, fossil cephalopods as a general group can be expected to vary considerably from the modern specimens because of evolutionary patterns of associated organisms, geographic distribution, and different environments with different paleoecological parameters through time. Caution in overreliance on the taphonomy of these modern shells should be exercised because of the limited sample of Nautilus specimens recovered. The need for additional taphonomic studies of modern externally shelled cephalopods with the recovery of more specimens from the marine environment is highly desirable.

Résumé [+]
[-]
The widespread assumption that COI and other mitochondrial genes will be ineffective DNA barcodes for anthozoan cnidarians has not been well tested for most anthozoans other than scleractinian corals. Here we examine the limitations of mitochondrial gene barcoding in the sub-class Octocorallia, a large, diverse, and ecologically important group of anthozoans.
Pairwise genetic distance values (uncorrected p) were compared for three candidate barcoding regions: the Folmer region of COI; a fragment of the octocoral-specific mitochondrial protein-coding gene, msh1; and an extended barcode of msh1 plus COI with a short, adjacent intergenic region (igr1). Intraspecific variation was <0.5%, with most species exhibiting no variation in any of the three gene regions. Interspecific divergence was also low: 18.5% of congeneric morphospecies shared identical COI barcodes, and there was no discernible barcoding gap between intra- and interspecific p values. In a case study to assess regional octocoral biodiversity, COI and msh1 barcodes each identified 70% of morphospecies. In a second case study, a nucleotide character-based analysis correctly identified 70% of species in the temperate genus Alcyonium.
Although interspecific genetic distances were 2 X greater for msh1 than COI, each marker identified similar numbers of species in the two case studies, and the extended COI + igr1 + msh1 barcode more effectively discriminated sister taxa in Alcyonium. Although far from perfect for species identification, a COI + igr1 + msh1 barcode nonetheless represents a valuable addition to the depauperate set of characters available for octocoral taxonomy.

Résumé [+]
[-]
The larvae of two species of the pylochelid genus Trizocheles are described from prematurely hatched specimens and compared with earlier described larvae of Pylocheles (Pylocheles) and Pomatocheles. Although all are lecithotrophic and exhibit marked advanced development, differences in the larval morphology among the three genera are profound. Consideration is given to these differences as they relate to development in the entire Paguroidea, and the possible impact they may have on pylochelid phylogeny. As one of the Trizocheles species is undescribed, adults as well as larvae are described and illustrated.

Résumé [+]
[-]
Additional materials of two species of the recently described pagurid genus Pteropagurus McLaughlin & Rahayu, 2006 have required an emendation of the genus. These have also provided the information needed to supplement the original species descriptions, including the unusual morphology of the male of P. spina McLaughlin & Rahayu, 2006 and the sexual dimorphism and variability found in P. spinulocarpus McLaughlin, 2007. Brief data on the larval development in Pteropagurus have been gleaned from zoeae prematurely hatched from one female of P. spinulocarpus. What heretofore had been considered a unique habitat for species of this genus, i.e. empty shells of a pelagic pteropod, was found to also provide carcinoecia for Catapagurus spinicarpus de Saint Laurent & McLaughlin, 2000, a species previously known only from its female holotype collected in the Kermadec Islands of New Zealand. Th e male of this species is described and species’ variability and dimorphic attributes are assessed. Consideration is given to the question of habitat choice and the morphological adaptations required for use of the unusual carcinoecia.

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 [+]
[-]
The unusual bathyal comatulid crinoid genus Atelecrinus is widespread in the Atlantic and tropical Pacific Oceans and currently includes three recognized species. A re-assessment based on examination of new and existing specimens requires establishment of two new genera and five new species, and returns three junior synonyms to species-level status. Paratelecrinus is erected to accommodate Atelecrinus wyvilli PH Carpenter, A. conifer AH Clark, A. cubensis PH Carpenter, P. orthotriremis, new species, P. amenouzume new species, P. laticonulus new species and P. telo new species. Adelatelecrinus is erected to accommodate Atelecrinus sulcatus AH Clark and Adelatelecrinus vallatus new species. Atelecrinus retains A. balanoides PH Carpenter and A. helgae AH Clark, which restricts the genus to the Atlantic. In both Paratelecrinus and Adelatelecrinus, the basals articulate with the centrodorsal via ligament bundles anchored in deep ring-like interradial pits that project into the centrodorsal cavity, whereas in Atelecrinus the centrodorsal rim has shallow interradial concavities and attaches to the basals via a tight junction with no obvious ligament bundles. The spoon-shaped aboral fossa in the basals of Paratelecrinus appears to be unique among articulate crinoids and differs from the smooth fossa found in both Atelecrinus and Adelatelecrinus. New material extends the range of the family to the Indian Ocean. A few species are now known from enough specimens to identify some ontogenetic and distributional variations. Proximal ray morphology varies substantially with size in P. cubensis and P. orthotriremis. A. balanoides generally occurs in deeper water in the Lesser Antilles than in the Bahamas and Strait of Florida, while P. orthotriremis occurs in shallower water in the Lesser Antilles and deeper in the Bahamas.

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 [+]
[-]
Recent examinations of newly obtained materials of dracunculoid nematodes (Dracunculoidea) parasitizing marine fishes off New Caledonia, South Pacific, revealed the presence of several nematodes of the genera Philometra Costa, 1845 (Philometridae) and Ichthyofilaria Yamaguti, 1935 (Guyanemidae), including the following four new species: Philometra priacanthi sp. n. (males) from the gonads of Priacanthus hamrur (Forsskal) (Priacanthidae), Philometra tenuicauda sp. n. (male and mature and gravid females) from the gonads of Lagocephalus sceleratus (Gmelin) (Tetraodontidae), Philometra dentigubernaculata sp. n. (males) from the oculo-orbit of Tylosurus crocodilus (Peron et Lesueur) (Belonidae), and Ichthyofilaria novaecaledoniensis sp. n. (subgravid female) from the musculature of Hoplichthys citrinus Gilbert (Hoplichthyidae). The new species are characterized mainly by the length and structure of spicules and the gubernaculum, body size, location in the host and by the type of hosts. In addition, the findings of Philometra lethrini Moravec et Justine, 2008 from the gonads of Lethrinus miniatus (Forster) and L. variegatus Valenciennes (both Lethrinidae) represent new host records for this parasite; for the first time, its subgravid females were found to be up to 350 mm long. The occurrence of Philometra ocularis Moravec, Ogawa, Suzuki, Miyazaki et Donai, 2002 in the oculo-orbit of Epinephelus areolatus (Forsskal) (Serranidae) off New Caledonia was confirmed.

Résumé [+]
[-]
A new species of majid crab, Sakaija amicitiae n. sp., is described from New Caledonia Exclusive Economic Zone, Vauban seamount and the Chesterfield Atolls. The species is superficially similar to S. japonica (Rathbun, 1932) and S. santo Ng & Richer de Forges, 2015, from Vanuatu. Specimens from New Caladonia previously referred to S. santo are now referred to the new species. Sakaija amicitiae n. sp. can be distinguished from congeners by features of the carapace spines, proportions of the ambulatory legs and structure of the male first gonopod.

Résumé [+]
[-]
The taxonomy of spider crabs of the genus Maja Lamarck, 1801, is revised, and a total of 36 species in 10 genera are now recognised from the eastern Atlantic, Mediterranean and Indo-West Pacific. The present revision describes seven genera and 17 species as new. Two genera previously synonymised under Maja: Paramaya De Haan, 1837, and Paramaja Kubo, 1936, are here treated as valid taxa. The confused nomenclature of Cancer cornutus Linnaeus, 1758, is resolved, and the name replaces Maja capensis Ortmann, 1894, and Mamaia queketti Stebbing, 1908. All genera and species are diagnosed and figured, and keys are provided for their identification.

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

Résumé [+]
[-]
A new genus and species of deep-sea Chrysogorgiidae Verrill, 1883, Pseudochrysogorgia bellona n. gen. n. sp., is described from colonies collected in the Coral Sea, West of New Caledonia (southwestern Pacific Ocean). These specimens bear resemblance to the genera Chrysogorgia Duchassaing & Michelotti, 1864 (dichotomously-subdivided branches arising from the main stem in a spiraling fashion; polyps characterized by ornamented sclerites) and Metallogorgia Versluys, 1902 (colony monopodial, hexagonal branching pattern). Additional material collected North of New Zealand (Otara Seamount) is used to complete the description of this new genus. Its taxonomic rank is discussed in light of morphology- and DNA-based phylogenetic inference and analysis of genetic distances among deep-sea chrysogorgiid genera.

Lack of Signal for the Impact of Conotoxin Gene Diversity on Speciation Rates in Cone Snails, in Serb J.(Ed.), Systematic Biology 68(5): 781-796. DOI:10.1093/sysbio/syz016
Résumé [+]

Abstract
Understanding why some groups of organisms are more diverse than others is a central goal in macroevolution. Evolvability, or the intrinsic capacity of lineages for evolutionary change, is thought to influence disparities in species diversity across taxa. Over macroevolutionary time scales, clades that exhibit high evolvability are expected to have higher speciation rates. Cone snails (family: Conidae, $>$900 spp.) provide a unique opportunity to test this prediction because their toxin genes can be used to characterize differences in evolvability between clades. Cone snails are carnivorous, use prey-specific venom (conotoxins) to capture prey, and the genes that encode venom are known and diversify through gene duplication. Theory predicts that higher gene diversity confers a greater potential to generate novel phenotypes for specialization and adaptation. Therefore, if conotoxin gene diversity gives rise to varying levels of evolvability, conotoxin gene diversity should be coupled with macroevolutionary speciation rates. We applied exon capture techniques to recover phylogenetic markers and conotoxin loci across 314 species, the largest venom discovery effort in a single study. We paired a reconstructed timetree using 12 fossil calibrations with species-specific estimates of conotoxin gene diversity and used trait-dependent diversification methods to test the impact of evolvability on diversification patterns. Surprisingly, we did not detect any signal for the relationship between conotoxin gene diversity and speciation rates, suggesting that venom evolution may not be the rate-limiting factor controlling diversification dynamics in Conidae. Comparative analyses showed some signal for the impact of diet and larval dispersal strategy on diversification patterns, though detection of a signal depended on the dataset and the method. If our results remain true with increased taxonomic sampling in future studies, they suggest that the rapid evolution of conid venom may cause other factors to become more critical to diversification, such as ecological opportunity or traits that promote isolation among lineages.

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.

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 [+]
[-]
During a broad molecular taxonomic and phylogenetic survey of the gastropod superfamily Conoidea,
80 specimens of several species of the genus Gemmuloborsonia were sequenced for the cytochrome c oxidase
subunit I gene. The genus, originally established for fossil species from the Plio-Pleistocene of the
Philippines, now includes living species from bathyal depths of the Indo-Pacific Oceans. The molecular
data demonstrated the presence of five separate entities, while only four ‘morphospecies’ could be isolated
by visual examination. The two largest groups, representing separate species from the molecular
data, were impossible to distinguish with certainty using shell or anatomical characters. To examine
shell morphology in more detail the shape of the last whorl was analysed by Fourier analysis, and the
Fourier coordinates were used in canonical variate analysis. The majority of the specimens were
separated into two groups, but 21.6% of the specimens were impossible to distinguish by morphological
characters. One of these two forms was attributed to the known species Gemmuloborsonia moosai Sysoev &
Bouchet, 1996, while the other is described as a new species Gemmuloborsonia clandestina. Bathytoma colorata
Sysoev & Bouchet, 2001 is transferred to Gemmuloborsonia on the basis of molecular analysis and radular
morphology. Another species, represented in our material by a single specimen, remains undescribed.

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.

The cone snails (family Conidae) are a hyperdiverse lineage of venomous gastropods. Two standard markers, COI and ITS2, were used to define six genetically divergent groups within a subclade of Conidae that includes Conus orbignyi; each of these was then evaluated based on their shell morphology. We conclude that three forms, previously regarded as subspecies of C. orbignyi are distinct species, now recognized as C. orbignyi, C. elokismenos and C. coriolisi. In addition, three additional species (C. pseudorbignyi, C. joliveti and C. comatosa) belong to this clade. Some of the proposed species (e. g. C. elokismenos) are possibly in turn complexes comprising multiple species. Groups such as Conidae illustrate the challenges generally faced in species delimitation in biodiverse lineages. In the case of C. orbignyi complex, they are not only definable, genetically divergent lineages, but also considerable geographical variation within each group. Our study suggests that an intensive analysis of multiple specimens within a single locality helps to minimize the confounding effects of geographical variation and can be a useful starting point for circumscribing different species within such a confusing complex.

Résumé [+]

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

Résumé [+]

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

Résumé [+]

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

A new species of glypheid of the previously monotypic genus Neoglyphea Forest & de Saint Laurent, 1975, N. neocaledonica n. sp., is described from deep waters in the Coral Sea. The unique female specimen is described and compared to the other species of the genus, N. inopinata Forest & de Saint Laurent, 1975. The two species can be easily separated by a series of characters: in N. neocaledonica n. sp., the general shape is more stout, the anterior part of the cephalothorax bears a series of dorsal carinas, the first pereiopods are shorter, the eyes larger, the coloration consists of spots pattern.

Résumé [+]
[-]
The genus Leiogalathea Baba, 1969 currently contains only two benthic species both occurring on the continental shelves and slope: L. laevirostris (Balss, 1913), widely reported in the Indo-Pacific region, and L. agassizii (A. Milne Edwards, 1880), from both sides of the Central Atlantic. A certain degree of morphological variability linked to their geographic distributions was previously noticed, mostly in L. laevirostris. In the present study, we revise numerous specimens collected from the Atlantic, Indian and Pacific Oceans, analysing morphological and molecular characters (COI and 16S rRNA). We found 15 new species; all of them are distinguished from L. laevirostris and L. agassizii by subtle but constant morphological differences and show clear genetic separation. Furthermore, L. imperialis (Miyake & Baba, 1967), previously synonymized with L. laevirostris, was found to be a valid species. All species are described and illustrated. Species of the genus Leiogalathea are morphologically distinguishable on the basis of the spinulation of the carapace, the shape and the armature of the rostrum, the shape of the propodi of the walking legs, and the pattern of the setae covering on rostrum, carapace and chelae. Some species are barely discernible on the basis of these characters but are highly divergent genetically.

Résumé [+]
[-]
The genus Phylladiorhynchus Baba, 1969 currently contains 11 species, all occurring in the shallow waters and on the continental shelf of the Indian and Pacific oceans. Recent expeditions in these oceans have resulted in the collection of numerous new specimens in need of analysis. We have studied this material using an integrative approach analysing both morphological and molecular (COI and 16S) characters. We describe 41 new species and resurrect three old names: P. integrus (Benedict, 1902) and P. lenzi (Rathbun, 1907), previously synonymized with P. pusillus (Henderson, 1885), and P. serrirostris (Melin, 1939), previously synonymized with P. integrirostris (Dana, 1852). Most species of the genus are described and illustrated. Some species are barely discernible on the basis of morphological characters but are highly divergent genetically. Species of Phylladiorhynchus are mainly distinguishable by the number of epigastric spines and lateral spines of the carapace, the shape and the armature of the rostrum, the number and pattern of the ridges on the carapace and pleon, the shape of thoracic sternite 3 and the armature of the P2–4 dactyli. A dichotomous identification key to all species is provided.

Rodríguez‐flores P.C., Buckley D., Macpherson E., Corbari L. & Machordom A. 2020. Deep‐sea squat lobster biogeography (Munidopsidae: Leiogalathea) unveils Tethyan vicariance and evolutionary patterns shared by shallow‐water relatives. Zoologica Scripta 49(3): 340-356. DOI:10.1111/zsc.12414
Résumé [+]
[-]
The ecology, abundance and diversity of galatheoid squat lobsters make them an ideal group to study deep-sea diversification processes. Here, we reconstructed the evolutionary and biogeographic history of Leiogalathea, a genus of circum-tropical deep-sea squat lobsters, in order to compare patterns and processes that have affected shallow-water and deep-sea squat lobster species. We first built a multilocus phylogeny and a calibrated species tree with a relaxed clock using StarBEAST2 to reconstruct evolutionary relationships and divergence times among Leiogalathea species. We used BioGeoBEARS and a DEC model, implemented in RevBayes, to reconstruct ancestral distribution ranges and the biogeographic history of the genus. Our results showed that Leiogalathea is monophyletic and comprises four main lineages; morphological homogeneity is common within and between clades, except in one; the reconstructed ancestral range of the genus is in the Atlantic and Indian oceans (Tethys). They also revealed the divergence of the Atlantic species around 25 million years ago (Ma), intense cladogenesis 15–25 Ma and low levels of speciation over the last 5 million years (Myr). The four Leiogalathea lineages showed similar patterns of speciation: allopatric speciation followed by range expansion and subsequent stasis. Leiogalathea started diversifying during the Oligocene, likely in the Tethyan. The Atlantic lineage then split from its Indo-Pacific sister group due to vicariance driven by closure of the Tethys Seaway. The Atlantic lineage is less speciose compared with the Indo-Pacific lineages, with the Tropical Southwestern Pacific being the current centre of diversity. Leiogalathea diversification coincided with cladogenetic peaks in shallow-water genera, indicating that historical biogeographic events similarly shaped the diversification and distribution of both deep-sea and shallow-water squat lobsters.

Résumé [+]
[-]
A review of species of the deep-sea sponge-associated shrimp genera Spongicola de Haan, 1844 and Paraspongicola de Saint Laurent & Cleva, 1981 (Decapoda, Stenopodidea) is presented on the basis of rich collections made by French expeditions in the Indo-West Pacific, supplemented by collections preserved in various institutions in the world. Seven species are recognized in Spongicola, of which three are new to science: S. venustus de Haan, 1844, S. andamanicus Alcock, 1901, S. levigatus Hayashi & Ogawa, 1987, S. parvispinus Zarenkov, 1990, S. depressus n. sp. from Loyalty Islands, S. goyi n. sp. from Japan, Indonesia, New Caledonia and Vanuatu, and S. robustus n. sp. from Mauritius and Mozambique. Subspecific division of S. andamanicus Alcock, 190 1, proposed by de Saint Laurenr & Cleva (198 1), is abandoned, since our morphological analysis strongly suggests that the division does not reflect a population structure of the species; S. holthuisi de Saint Laurent & Cleva, 198 1, is also reduced to a junior synonym of S. andamanicus. Two species are recognized in Paraspongicola, both previously described, viz. P. pusillus de Saint Laurent & Cleva, 1981 and P. inflatus (de saint Laurent & Cleva, 198 1) n. comb., of which the latter is here transferred from Spongicola. Keys in aid for identification are provided for each genus. Geographic and bathymetric distributions of species are briefly discussed. Association with host sponges was verified for some species.

Résumé [+]
[-]
Bursidae Thiele, 1925 is a moderately diverse group of extant tonnoidean gastropods with a significant fossil record. We review the fossil record of the family. We exclude some taxa from Bursidae, particularly the most ancient ones: Hanaibursa aquilana (Parona, 1909) (Aptian) and Bursa saundersi Adegoke, 1977 (Selandian). We exclude the genus Olequahia Stewart, 1926; its posterior siphonal canal is not analogous with that of Bursidae. We also discuss the possible revision of the type genus, Bursa Röding, 1798, on the basis of previously published phylogenies; the genus is not monophyletic. We create two new genera, Olssonia n. gen. (type species: Bursa chira Olsson, 1930) and Aquitanobursa n. gen. (type species: Ranella grateloupi d’Orbigny, 1852), containing only fossil species. Lectotypes are designated for Ranella grateloupi d’Orbigny, 1852, Ranella morrisi d’Archiac & Haime, 1853 and Apollon pelouatensis Cossmann & Peyrot, 1924. Based on this revision of the fossil record, we propose five fossil calibration points that can be used to date molecular phylogenetic trees of Bursidae.

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

A new genus and 13 new species of Scaphopoda (ten Dentaliida and three Gadilida) are described from the tropical Pacific Ocean in the Coral Sea, Solomon Islands, Vanuatu, Fiji, Wallis Island and Tonga. The new genus is named Boissevainia n. gen. and the new species are Paradentalium choneides n. sp., P. danielleae n. sp., Fustiaria electra n. sp., F. diaphana n. sp., Gadilina lauensis n. sp., Episiphon joanae n. sp., E. wallisi n. sp., E. indefensum n. sp., E. kantori n. sp., E. lacteum n. sp. (Dentaliida); Bathoxiphus kathieae n. sp., Annulipusellum aenigmaticum n. sp. and Boissevainia mossiae n. gen., n. sp. (Gadilida). The new taxa not only highlight the diversity of the class in the tropical Pacific Ocean, but also indicate the presence of morphologies not yet recorded for the region or described for the class.

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

Résumé [+]
[-]
The taxonomy of the order Zoantharia ( = Zoanthidea = Zoanthiniaria) is greatly hampered by the paucity of diagnostic morphological features. To facilitate discrimination between similar zoanthids, a combination of morphological and molecular analyses is applied here. The three most abundant zoanthid species in shallow waters of the southern Chilean fjord region are described. Comparison with other zoanthids using molecular markers reveals that two of them are new to science; these are described as Mesozoanthus fossii gen. n., sp. n. and Epizoanthus fiordicus sp. n. Their representatives grow on rocky substratum and do not live in symbiosis with demosponges. In the less abundant M., fossii, animals tire greyish in colour and resemble members of Parazoanthus in growth form. Individual polyps can be tip to 35 mm long. The more abundant E. fordicus are also greyish; the polyps arise froth thin stolons and reach only 12 mm in length. The third species studied is Parazoanthus elongatus McMurrich, 1904. For these three Chilean zoanthid species, in-situ photographs are presented as well as information on distribution, habitat and associated species. Establishment of the Mesozoanthus Pen. n. is of particular importance to taxonomy in the chaotic suborder Macrocnemina. (C) 2008 Gesellschaft fur Biologische Systemalik. Published by Elsevier GmbH.

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

Résumé [+]
[-]
La majorité des informations disponibles sur les minéralisations marines profondes au sein de la ZEE de Nouvelle-Calédonie provient des travaux entrepris par l’ORSTOM (IRD) entre 1970 et 1980. L’objectif de ce projet, mené conjointement entre l’Institut Français pour l'Exploitation de la Mer (IFREMER), le Service Géologique de Nouvelle-Calédonie (SGNC) et l'Agence de Développement Économique de Nouvelle- Calédonie (ADECAL) est de mettre à jour les connaissances sur ces dépôts en utilisant des méthodes analytiques modernes. L'inventaire de tous les échantillons de dragages existants en Nouvelle-Calédonie depuis 1970 a permis de mettre en évidence 104 échantillons présentant des encroûtements au sein et à proximité de la ZEE. Ces échantillons sont principalement localisés au Sud-Est de la Nouvelle-Calédonie, mais également au Nord dans la continuité de la Ride des Loyauté et à l'Ouest sur les monts sous-marins de la Ride de Lord Howe. Une caractérisation chimique et minéralogique de ces minéralisations (XRD/XRF, MEB et ICP-MS) a permis de confirmer qu'elles sont pour la plupart des encroûtements ferromanganésifères hydrogénés, et a également mis en évidence l’originalité de certaines minéralisations associées à une activité hydrothermale et/ou diagénétique, dont la description et l'analyse sont une première en Nouvelle-Calédonie. Les encroûtements ferromanganésifères hydrogénés sont enrichis en métaux de base, traces et terres rares (17,4% Mn, 20,8% Fe, 0,42% Co, 0,31% Ni et 1 307 ppm ΣREE), alors que les minéralisations hydrothermales et/ou diagénétiques sont appauvries en métaux traces et terre rares, mais présentent pour quelques-unes des concentrations fortes en Mn (plus de 50%) et Ni (jusqu'à 0,7%). La comparaison de ces résultats avec ceux issus d'autres océans du globe montre que la Nouvelle-Calédonie se situe dans la moyenne des concentrations en métaux. Les fortes concentrations en Co, Ni et Cu de certains échantillons, ainsi que la physiographie particulière de la zone Sud des rides de Loyauté et de Norfolk, en font une des zones les plus propice pour des investigations supplémentaires. Une première approche, couplant les données de prélèvements, de réflectivité du fond et de bathymétrie haute-résolution, a permis de tester une méthode de prédectivité de présence d'encroûtement sur les sites les plus intéressants et potentiellement minéralisés. La robustesse de ces cartes a été testée en comparant les zones potentielles avec des données vidéo ROV de fonds marins acquises lors de la campagne KANADEEP II. Cette étude a permis de répertorier pour la première fois les minéralisations Fe-Mn de la ZEE de Nouvelle- Calédonie, et d'en caractériser leurs grandes diversités, compositions et morphologies. L'effort d'échantillonnage reste malgré tout insuffisant pour poursuivre l'évaluation du potentiel économique. La poursuite de cette évaluation nécessite la réalisation de campagnes d'exploration dédiées avec des méthodes d'échantillonnage et d'acquisition de données propres à l'étude des minéralisations profondes.

Résumé [+]
[-]
Located in the South-West Pacific, at the northern extremity of the mostly submerged Zealandia continent, the New Caledonian Exclusive Economic Zone (EEZ) covers 1,470,000 km2 and includes basins, ridges and seamounts where abundant ferromanganese crusts have been observed. Several investigations have been conducted since the 1970s on the nature and composition of ferromanganese crusts from New Caledonia’s seamounts and ridges, but none have covered the entire EEZ. We present data from 104 ferromanganese crusts collected in New Caledonia’s EEZ during twelve oceanographic cruises between 1974 and 2019. Samples were analysed for mineralogy, geochemical compositions, growth rates, and through a statistical approach using correlation coefficients and factor analysis. Crust thicknesses range from 1 mm to 115 mm, with growth rates between 0.45 mm/Ma and 102 mm/Ma. Based on textures, structures, discrimination plots, and growth rates, we distinguish a group of hydrogenetic crusts containing the highest mean contents of Co (0.42 wt%), Ni (0.31 wt%), and high contents of Mo, V, W, Pb, Zn, Nb, from a group of hydrothermal and/or diagenetic deposits showing high mean contents of Mn (38.17 wt%), Ba (0.56 wt%) and low contents of other trace metals. Several samples from this later group have exceptionally high content of Ni (0.7 wt%). The data shows that crusts from the southern part of the EEZ, notably seamounts of the Loyalty Ridge and the Lord Howe Rise, present high mineral potential for prospectivity owing to high contents of valuable metals, and constitute a great target for further investigation.

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

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

Sumner-rooney L., Sigwart J.D., Mcafee J., Smith L. & Williams S.T. 2016. Repeated eye reduction events reveal multiple pathways to degeneration in a family of marine snails: EYE REDUCTION IN A FAMILY OF MARINE SNAILS. Evolution 70(10): 2268-2295. 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.

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

Résumé [+]
[-]
The genus Profundiconus Kuroda, 1956 is reviewed. The morphological characters of the shell, radular tooth and internal anatomy of species in Profundiconus are discussed. In particular, we studied Profundiconus material collected by dredging in deep water during different scientific campaigns carried out in the Solomon Islands, Madagascar, Papua New Guinea and New Caledonia. We reconstructed a phylogeny of 55 individuals based on partial mitochondrial cox1 gene sequences. The phylogeny shows several clades containing individuals that do not match any of the known species of Profundiconus based on their shell and radular morphologies, and are introduced here as five new species: Profundiconus maribelae sp. nov. from the Solomon Islands; P. virginiae sp. nov. from Chesterfield Plateau (New Caledonia); P. barazeri sp. nov. from Chesterfield Plateau and the Grand Passage area (New Caledonia); P. puillandrei sp. nov. from Norfolk Ridge (New Caledonia), Kermadec Ridge (New Zealand) and possibly Balut Island (Philippines); and P. neocaledonicus sp. nov. from New Caledonia. Furthermore, Profundiconus teramachii forma neotorquatus (da Motta, 1984) is raised to specific status as P. neotorquatus (da Motta, 1984).

Ter poorten J.J. 2013. Revision of the Recent species of the genus Nemocardium Meek, 1876 (Bivalvia, Cardiidae), with the descriptions of three new species. Basteria 77(4-6): 45-73
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.

Résumé [+]
[-]
Cephalopod shells can be affected by postmortem transport and biostratigraphic condensation, but direct estimates of the temporal and spatial resolutions of cephalopod assemblages are missing. Amino acid racemisation calibrated by 14C demonstrates a centennial-scale time averaging (<500 years) of Nautilus macromphalus in sediment-starved, epi- and mesobathyal pelagic environments. The few shells that are thousands of years old are highly degraded. The median occurrence of dead shells is at 445 m depth, close to the 300–400 m depth where living N. macromphalus are most abundant. Therefore, dead shells of this species accumulate at a centennial temporal resolution and with excellent bathymetric fidelity. Dead Nautilus shells exist for only a few hundred years on the seafloor, in contrast to the biostratigraphically condensed mixture of extant foraminifers and foraminifers that went extinct during the Pleistocene. Cephalopod shells that do not show any signs of early diagenetic cementation are unlikely to be biostratigraphically condensed.

Helgoland Marine Research 68(3): 379-397. DOI:10.1007/s10152-014-0397-0
Résumé [+]
[-]
A total of 25 specimens of Eryoneicus larvae were collected near the Balearic Archipelago (Western Mediterranean Sea) in 2009 and 2010. Detailed morphological examination indicated that the smallest individual corresponded with the first zoea (ZI) stage of Polycheles typhlops hatched from a berried female by Guerao and Abello (J Nat Hist 30(8):1179–1184, 1996). Only two species of deep-sea polychelid lobster, namely P. typhlops and Stereomastis sculpta, are known to occur in the Mediterranean. Genetic distance comparisons and phylogenetic analysis of the mitochondrial 16S rDNA and Cox I genes of this early larva together with adults from several Polycheles and Stereomastis species allowed us to assign it to P. typhlops. This is the first wild-caught larval stage of a polychelid lobster being identified using molecular techniques. The remaining specimens were attributed to zoeal stages II–III and decapodid stage based on morphological comparison. The arrangement of spines along the anterior part of the middorsal line (R, 1, 1, 1, 2, C1), characteristic of the former species E. puritanii, discriminates these larvae from other Eryoneicus found in the Mediterranean. The clear presence of epipods on the third maxilliped and pereiopods of the decapodid stage gives further support to the identification of E. puritanii as the larval stages of P. typhlops. Additionally, information on the ecology of these larvae, their abundances during different seasons, as well as their bathymetric distribution is reported.

Elaphriella n. gen. is a new genus of small to fairly large (up to 18 mm) solariellids superficially resembling the genus Archiminolia Iredale, 1929. The latter differs, among others, by a much thicker columella, spiral cords or grooves that often continue on the body whorl and spiral cords inside the umbilicus. The two genera form distinct clades in a molecular phylogeny of the family Solariellidae. Seven new species are described, all from deep water (300-900 meters) in the South and West Pacific: Elaphriella cantharos n. sp., E. eukhonikhe n. sp., E. paulinae n. sp., E. wareni n. sp., E. dikhonikhe n. sp., E. helios n. sp. and E. leia n. sp.

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 [+]

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

Members of genus Iridogorgia Verrill, 1883 are the typical deep-sea megabenthos with only seven species reported. Based on an integrated morphological-molecular approach, eight sampled specimens of Iridogorgia from seamounts in the tropical Western Pacific are identified as three new species, and two known species I. magnispiralis Watling, 2007 and I. densispicula Xu, Zhan, Li and Xu, 2020. Iridogorgia flexilis sp. nov. is unique in having a very broad polyp body base with stout and thick scales. Iridogorgia densispiralis sp. nov. can be distinguished by rods present in both polyps and coenenchyme, and I. verrucosa sp. nov. is characterized by having numerous verrucae in coenenchyme and irregular spindles and scales in the polyp body wall. Phylogenetic analysis based on the nuclear 28S rDNA indicated that I. densispiralis sp. nov. showed close relationships with I. splendens Watling, 2007 and I. verrucosa sp. nov., and I. flexilis sp. nov. formed a sister clade with I. magnispiralis. In addition, due to Rhodaniridogorgia fragilis Watling, 2007 nested into the Iridogorgia clade in mtMutS-COI trees and shared highly similar morphology to the latter, we propose to eliminate the genus Rhodaniridogorgia by establishing a new combination Iridogorgia fragilis (Watling, 2007) comb. nov. and resurrecting I. superba Nutting, 1908.

Abstract
The practice of species delimitation using molecular data commonly leads to the revealing of species complexes and an increase in the number of delimited species. In a few instances, however, DNA-based taxonomy has led to lumping together of previously described species. Here, we delimit species in the genus Cryptogemma (Gastropoda: Conoidea: Turridae), a group of deep-sea snails with a wide geographical distribution, primarily by using the mitochondrial COI gene. Three approaches of species delimitation (ABGD, mPTP and GMYC) were applied to define species partitions. All approaches resulted in eight species. According to previous taxonomic studies and shell morphology, 23 available names potentially apply to the eight Cryptogemma species that were recognized herein. Shell morphometrics, radular characters and geographical and bathymetric distributions were used to link type specimens to these delimited species. In all, 23 of these available names are here attributed to seven species, resulting in 16 synonymizations, and one species is described as new: Cryptogemma powelli sp. nov. We discuss the possible reasons underlying the apparent overdescription of species within Cryptogemma, which is shown here to constitute a rare case of DNA-based species lumping in the hyper-diversified superfamily Conoidea.

Résumé [+]

During two expeditions to seamounts near the Mariana Trench in the tropical western Pacific, several trochiform shells from the upper bathyal zone were sampled. Morphological observations of these specimens suggest that they represent two new species that belong to the family Trochidae, but the shell morphology, radular plan, and external anatomy differ considerably from those of closely related genera. A new subfamily, Carinotrochinae subfam. nov., and a new genus, Carinotrochus gen. nov., are proposed herein to accommodate these two species. Carinotrochus marianaensis sp. nov., the type species, was associated with coral debris at a depth of 865 m, and Carinotrochus williamsae sp. nov. was discovered crawling on a hydroid Stegolaria sp. that was attached to a dead bamboo coral at a depth of 1332 m. Genertic analysis of mitochondrial COI, 16S rRNA, and nuclear 28S rRNA genes using maximum likelihood, Bayesian inference, and pairwise uncorrected p-distances confirmed that the new taxa are trochids but do not belong to any existing defined subfamily. Molecular clock analysis based on concatenated sequences (COI, 16S, and 28S) indicated that Carinotrochinae subfam. nov. split from its shallow water sister subfamily Trochinae roughly 80 Mya during the Late Cretaceous.
