Abdelkrim J., Aznar-cormano L., Buge B., Fedosov A., Kantor Y., Zaharias P. & Puillandre N. 2018. Delimiting species of marine gastropods (Turridae, Conoidea) using RAD sequencing in an integrative taxonomy framework. Molecular Ecology 27(22): 4591-4611. DOI:10.1111/mec.14882
Résumé [+] [-]Species delimitation in poorly known and diverse taxa is usually performed based on monolocus, DNA-barcoding-like approaches, while multilocus data are often used to test alternative species hypotheses in well-studied groups. We combined both approaches to delimit species in the Xenuroturris/Iotyrris complex, a group of venomous marine gastropods from the Indo-P acific. First, COI sequences were analysed using three methods of species delimitation to propose primary species hypotheses. Second, RAD sequencing data were also obtained and a maximum-likelihood phylogenetic tree produced. We tested the impact of the level of missing data on the robustness of the phylogenetic tree obtained with the RAD-seq data. Alternative species partitions revealed with the COI data set were also tested using the RAD-seq data and the Bayes factor species delimitation method. The congruence between the species hypotheses proposed with the mitochondrial nuclear data sets, together with the morphological variability of the shell and the radula and the distribution pattern, was used to turn the primary species hypotheses into secondary species hypotheses. Allopatric primary species hypotheses defined with the COI gene were interpreted to correspond to intraspecific structure. Most of the species are found sympatrically in the Philippines, and only one is confidently identified as a new species and described as Iotyrris conotaxis n. sp. The results obtained demonstrate the efficiency of the combined monolocus/multilocus approach to delimit species.

Abdelkrim J., Aznar-cormano L., Fedosov A.E., Kantor Y.I., Lozouet P., Phuong M.A., Zaharias P. & Puillandre N. 2018. Exon-Capture-Based Phylogeny and Diversification of the Venomous Gastropods (Neogastropoda, Conoidea), in Vidal N.(Ed.), Molecular Biology and Evolution 35(10): 2355-2374. DOI:10.1093/molbev/msy144
Résumé [+] [-]Transcriptome-based exon capture methods provide an approach to recover several hundred markers from genomic DNA, allowing for robust phylogenetic estimation at deep timescales. We applied this method to a highly diverse group of venomous marine snails, Conoidea, for which published phylogenetic trees remain mostly unresolved for the deeper nodes. We targeted 850 protein coding genes (678,322 bp) in ca. 120 samples, spanning all (except one) known families of Conoidea and a broad selection of non-Conoidea neogastropods. The capture was successful for most samples, although capture efficiency decreased when DNA libraries were of insufficient quality and/or quantity (dried samples or low starting DNA concentration) and when targeting the most divergent lineages. An average of 75.4% of proteins was recovered, and the resulting tree, reconstructed using both supermatrix (IQ-tree) and supertree (Astral-II, combined with the Weighted Statistical Binning method) approaches, are almost fully supported. A reconstructed fossil-calibrated tree dates the origin of Conoidea to the Lower Cretaceous. We provide descriptions for two new families. The phylogeny revealed in this study provides a robust framework to reinterpret changes in Conoidea anatomy through time. Finally, we used the phylogeny to test the impact of the venom gland and radular type on diversification rates. Our analyses revealed that repeated losses of the venom gland had no effect on diversification rates, while families with a breadth of radula types showed increases in diversification rates, thus suggesting that trophic ecology may have an impact on the evolution of Conoidea.

Austin J., Gosliner T. & Malaquias M.A.E. 2018. Systematic revision, diversity patterns and trophic ecology of the tropical Indo-West Pacific sea slug genus Phanerophthalmus A. Adams, 1850 (Cephalaspidea, Haminoeidae). Invertebrate Systematics 32: 1336-1387. DOI:10.1071/IS17086
Résumé [+] [-]Phanerophthalmus is a genus of Indo-West Pacific sea slugs inhabiting seagrass and coral reefs with up to now seven species currently recognised as valid. The goals of this study are to revise the systematics of Phanerophthalmus, infer its phylogeny and patterns of diversity, as well as study its diet. Morphology was combined with molecular phylogenetics based on two mitochondrial (cytochrome c oxidase subunit I, 16S rRNA) and one nuclear (28S rRNA) genes. Molecular species delimitation methods (ABGD, DISSECT) were employed to aid delimiting species. Diet was assessed by gut content analysis. Seventeen species were recognised, 10 of them new to science (P. albotriangulatum, sp. nov., P. anettae, sp. nov., P. batangas, sp. nov., P. boucheti, sp. nov., P. cerverai, sp. nov., P. lentigines, sp. nov., P. paulayi, sp. nov., P. purpura, sp. nov., P. rudmani, sp. nov., P. tibiricae, sp. nov.). Phanerophthalmus has its highest diversity in the Western Pacific where 13 species occur with a peak in the Coral Triangle (11 species; three only known from here). Diversity decreases towards the Central Pacific with five species and Indian Ocean/Red Sea with four species. Only two species are distributed across the Indo-West Pacific. Preliminary gut content analysis suggests these slugs feed on diatoms.

Aznar-cormano L., Brisset J., Chan T., Corbari L., Puillandre N., Utgé J., Zbinden M., Zuccon D. & Samadi S. 2015. An improved taxonomic sampling is a necessary but not sufficient condition for resolving inter-families relationships in Caridean decapods. Genetica 143(2): 195-205. DOI:10.1007/s10709-014-9807-0
Résumé [+] [-]During the past decade, a large number of multi-gene analyses aimed at resolving the phylogeneticrelationships within Decapoda. However relationships among families, and even among sub-families, remain poorly defined. Most analyses used an incomplete and opportunistic sampling of species, but also an incomplete and opportunistic gene selection among those available for Decapoda. Here we test in the Caridea if improving the taxonomic coverage following the hierarchical scheme of the classification, as it is currently accepted, provides a better phylogenetic resolution for the inter-families relationships. The rich collections of the Muse´um National d’Histoire Naturelle de Paris are used for sampling as far as possible at least two species of two different genera for each family or subfamily. All potential markers are tested over this sampling. For some coding genes the amplification success varies greatly among taxa and the phylogenetic signal is highly saturated. This result probably explains the taxon-heterogeneity among previously published studies. The analysis is thus restricted to the genes homogeneously amplified over the whole sampling. Thanks to the taxonomic sampling scheme the monophyly of most families is confirmed. However the genes commonly used in Decapoda appear non-adapted for clarifying inter-families relationships, which remain poorly resolved. Genome-wide analyses, like transcriptome-based exon capture facilitated by the new generation sequencing methods might provide a sounder approach to resolve deep and rapid radiations like the Caridea.

Bronstein O., Kroh A. & Haring E. 2018. Mind the gap! The mitochondrial control region and its power as a phylogenetic marker in echinoids. BMC Evolutionary Biology 18: 80. DOI:10.1186/s12862-018-1198-x
Résumé [+] [-]Background: In Metazoa, mitochondrial markers are the most commonly used targets for inferring species-level molecular phylogenies due to their extremely low rate of recombination, maternal inheritance, ease of use and fast substitution rate in comparison to nuclear DNA. The mitochondrial control region (CR) is the main non-coding area of the mitochondrial genome and contains the mitochondrial origin of replication and transcription. While sequences of the cytochrome oxidase subunit 1 (COI) and 16S rRNA genes are the prime mitochondrial markers in phylogenetic studies, the highly variable CR is typically ignored and not targeted in such analyses. However, the higher substitution rate of the CR can be harnessed to infer the phylogeny of closely related species, and the use of a non-coding region alleviates biases resulting from both directional and purifying selection. Additionally, complete mitochondrial genome assemblies utilizing next generation sequencing (NGS) data often show exceptionally low coverage at specific regions, including the CR. This can only be resolved by targeted sequencing of this region. Results: Here we provide novel sequence data for the echinoid mitochondrial control region in over 40 species across the echinoid phylogenetic tree. We demonstrate the advantages of directly targeting the CR and adjacent tRNAs to facilitate complementing low coverage NGS data from complete mitochondrial genome assemblies. Finally, we test the performance of this region as a phylogenetic marker both in the lab and in phylogenetic analyses, and demonstrate its superior performance over the other available mitochondrial markers in echinoids. Conclusions: Our target region of the mitochondrial CR (1) facilitates the first thorough investigation of this region across a wide range of echinoid taxa, (2) provides a tool for complementing missing data in NGS experiments, and (3) identifies the CR as a powerful, novel marker for phylogenetic inference in echinoids due to its high variability, lack of selection, and high compatibility across the entire class, outperforming conventional mitochondrial markers.

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

Résumé [+] [-]Quelles sont les étapes qui permettent à un coquillage collecté dans les fonds marins du sud de Madagascar de devenir un objet « scientifique » ? Quelles sont les traductions-circulations qui donnent une nouvelle vie à un mollusque dans des collections, à l’autre bout du monde ? Contrairement à l’idée que la science se produit exclusivement en laboratoire et à travers le jeu exclusif des abstractions, l’article décrit les processus de collecte à grande échelle initiés par le Muséum National d’Histoire Naturelle, qui construisent méticuleusement la base taxonomique de la biologie marine, en manipulant d’intenses flux de spécimens matériels. Cinq dimensions de cette circulation sont précisément analysées : circulation géographique entre six localités (du lieu de collecte aux collections) qui dessinent une sorte de laboratoire distribué, série de manipulations par des individus variés et diversement instrumentés, transferts successifs de contenants permettant de confiner-séparer-emboîter, agrégation progressive d’informations accompagnant le spécimen permettant d’établir sa nouvelle carte d’identité, et enfin, multitude d’accidents de parcours possibles qui bouleversent ces trajectoires linéaires. La complexité de cette chaîne sera largement invisible, alors que cette dynamique field to lab dessine une forme importante de scientifisation.

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

Résumé [+] [-]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.

The collapse of Mitra: molecular systematics and morphology of the Mitridae (Gastropoda: Neogastropoda). Zoological Journal of the Linnean Society 20: 1-85. DOI:10.1093/zoolinnean/zlx073/4855867
Résumé [+] [-]Alongside confirmation of the monophyly of the gastropod family Mitridae, a recent molecular phylogenetic analysis disclosed multiple inconsistencies with the existing taxonomic framework. In the present study, we expanded the molecular sampling to 103 species, representing 26% of the 402 extant species currently accepted in the family and 16 of the 19 currently accepted extant genera; 83 species were sequenced for four molecular markers [cytochrome c oxidase subunit I (COI), 16S and 12S rRNA, and H3 (Histone 3)]. Molecular analyses were supplemented by morphological studies, focused on characters of the radula and, in a more restricted data set, proboscis anatomy. These data form the basis for a revised classification of the Mitridae. A first dichotomy divides mitrids into two unequal clades, Charitodoron and the Mitridae s.s. Species of Charitodoron show profound differences to all other Mitridae in foregut anatomy (lacking an epiproboscis) and shell morphology (smooth columella, bulbous protoconch of non-planktotrophic type), which leads to the erection of the separate family Charitodoronidae fam. nov. Three traditional subfamilies (Mitrinae, Cylindromitrinae and Imbricariinae) correspond to three of the inferred phylogenetic lineages of Mitridae s.s.; we redefine their contents, reinstate Strigatellinae Troschel, 1869 as valid and establish the new subfamily Isarinae. In the absence of molecular material, a sixth subfamily, Pleioptygmatinae, is included in Mitridae based on morphological considerations only. To resolve the polyphyly of Mitra and Cancilla in their current taxonomic extension, we reinstate the genera Episcomitra Monterosato, 1917, Isara H. & A. Adams, 1853 and Probata Sarasúa, 1989 and establish 11 new genera: Quasimitra, Roseomitra, Fusidomiporta, Profundimitra, Cancillopsis, Pseudonebularia, Gemmulimitra and Neotiara in Mitrinae; Imbricariopsis in Imbricariinae; Carinomitra and Condylomitra are left unassigned to a subfamily. Altogether 32 genera are recognized within the family. Their diversity and distribution are discussed, along with general trends in morphological evolution of the family.

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

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

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

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

Résumé [+] [-]Caesio xanthalytos, a new species of fusilier, closely related to Caesio caerulaurea Lacepède 1801, is described from several specimens from various localities on the east coast of Africa, and from southern Madagascar. While very similar in colour pattern to C. caerulaurea, its lateral line lies within a dominant, composite yellow stripe, whereas in C. caurulaurea the lateral line lies immediately below the yellow stripe. The two species also differ in the number of lateral-line scales, the modal number of pectoral-fin rays, in the form of the nuchal scale patch, and genetically. The new species has been observed to school with C. caerulaurea and with C. varilineata Carpenter 1987. The ranges of several species of Caesio and Pterocaesio and of Dipterygonotus balteatus and Gymnocaesio gymnoptera are extended to localities on the South African east coast.

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).

Kantor Y.I., Horro J., Rolán E. & Puillandre N. 2018. Paraclavatula (Gastropoda: Conoidea: Clavatulidae), a new genus with a distinctive radula type from West Africa. Journal of Molluscan Studies 84(3): 275-284. DOI:10.1093/mollus/eyy012
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 [+] [-]Most neogastropod families have a continuous record from the Cretaceous or Paleogene to the Recent. However, the fossil record also contains a number of obscure nominal families with unusual shell characters that are not adequately placed in the current classification. Some of these are traditionally regarded as valid, and some have been “lost” in synonymy. One such “lost” family is the Pyramimitridae, established by Cossmann in 1901 for the Eocene genus Pyramimitra, and currently included in the synonymy of Buccinidae. Examination of several species of inconspicuous, small turriform gastropods has revealed a radula type so far unknown in Neogastropoda, and their shell characters identify them as members of the "extinct" family Pyramimitridae. Neither the radular morphology nor the anatomy reveal the relationships of this enigmatic, “living fossil” family. Molecular data (12S, 16S, 28S, COI) confirm the recognition of Pyramimitridae as a distinct family, but no sister group was identified in the analysis. The family Pyramimitridae Cossmann, 1901, is thus restored as a valid family of Neogastropoda that includes the genera Pyramimitra Conrad, 1865, Endiatoma Cossmann, 1896, Vaughanites Woodring, 1928, Hortia Lozouet, 1999, and Teremitra new genus. Pyramimitrids occur in the Recent fauna at bathyal depths of the Indo- Pacific from Taiwan to Madagascar and New Zealand, with three genera and nine species (all but one new).

Résumé [+] [-]Five new species of Olivoidea are described based on molecular and morphological evidence: four shallow subtidal Ancilla from Madagascar and Papua New Guinea, and one deep water (500-600 m) Calyptoliva from the Tuamotus. The sympatric – but not syntopic - Ancilla morrisoni and A. kaviengensis, from New Ireland province, are morphologically cryptic, differing mostly in shell colour, but are molecularly distinct. The sympatric – and possibly syntopic – Ancilla atimovatae and A. lhaumeti, belong to a species flock from southernmost Madagascar; A. atimovatae is conchologically nearly indistinguishable from A. ventricosa, but differs markedly in radular morphology. Calyptoliva was previously known only from the Coral Sea; C. bbugae is the first representative of the genus to yield molecular data. The new Ancilla are described based on sequenced holotypes; the type material of the new Calyptoliva includes a sequenced paratype.

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

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

Résumé [+] [-]A new species of scorpaenid fish, Ebosia vespertina sp. nov., is described on the basis of 19 specimens from off Mozambique, South Africa, and Madagascar, southwestern Indian Ocean. The new species is most similar to Ebosia falcata and Ebosia saya, known from the northern and eastern Indian Ocean and Saya de Malha Bank, respectively, in having usually 8 anal-fin soft rays, usually more than 17 pectoral-fin rays, and the elongated parietal spine in males narrow and strongly curved posterodorsally. However, E. vespertina can be distinguished from the two latter species by the following combination of characters: pectoral-fin rays 17–18 (modally 18); scale rows above the lateral line 4–6 (5); scale rows between the last dorsal-fin spine base and lateral line 4–5 (5); scale rows between the sixth dorsal-fin spine base and lateral line 4–5 (5); postorbital length 17.4–20.3 (mean 18.7) % of standard length (SL); longest pectoral-fin ray length 54.6–73.9 (65.1) % of SL; longest pelvic-fin soft ray length 32.4–44.0 (37.6) % of SL. The remaining congener, Ebosia bleekeri, known from the western Pacific Ocean, usually has 7 analfin soft rays and 16 pectoral-fin rays, and the elongated parietal spine in males relatively broad and not so strongly curved.

Monniot F. 2012. Some ascidians from the southern coast of Madagascar collected during the “AtimoVatae” survey. Zootaxa 3197: 1-42
Résumé [+] [-]Surveys of littoral invertebrates along the southern coast of Madagascar have produced the first study of ascidians in this part of the Indian Ocean. Collections were made by SCUBA divers in May and June 2010 down to 25m depth. This region is considered the southern limit for coral reefs but remains diverse biologically. Upwellings and an abundant plankton community particularly favour the abundance of ascidians in this area. Of the 39 species of non-didemnid species described here, eight are new. Ten species are common to South Africa. Other species were for the most part already known from the Mozambique Channel and a few have also been recorded in the western Pacific (either cosmopolitan or introduced).

Résumé [+] [-]The systematic positions of two ocypodoid crabs, Paracleistostoma dentatum Tesch, 1918, and P. fossulum Barnard, 1955, have been uncertain because each were described from single female specimens, with Ng et al. (2008) referring them provisionally to the Dotillidae and Varunidae, respectively. Stevcic (2011) recently established two new genera, Lazarocleistostoma Stevcic, 2011, and Brankocleistostoma Stevcic, 2011, for P. dentatum Tesch, 1918, and P. fossulum Barnard, 1955, respectively. He also recognised two new families, Lazarocleistostomidae Stevcic, 2011, and Brankocleistostomidae Stevcic, 2011, for these genera. Examination of the types and fresh material of P. fossulum indicates that while both genera are valid, the families are not justified. Brankocleistostoma is a dotillid; while Lazarocleistostoma is a varunid (subfamily Gaeticinae). The tribe Gopkittisakini Stevcic, 2011 (type genus Gopkittisak Naruse & Clark, 2009), is also shown to be a junior synonym of Gaeticinae.

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

Nielsen J.G. & Uiblein F. 2014. The West Pacific Neobythites bimarginatus (Ophidiidae) recorded from off Madagascar. Cybium 38(4): 309–310
Résumé [+] [-]Neobythites is the largest known ophidiid genus with 52 valid species. It is commonly found on the lower part of the Continental Shelf and the upper part of the Continental Slope in the subtropical and tropical areas of all oceans, except for the East Atlantic Ocean. In 2010 a Neobythites specimen was caught off Madagascar. Twelve Neobythites species are known from the westernmost Indian Ocean (Nielsen, 1995), but the present specimen differs from them all, e.g., by the coloration of the dorsal and anal fins. Following the revision of the Indo-Pacific Neobythites species (Nielsen, 2002) it keys clearly out as N. bimarginatus Fourmanoir & Rivaton, 1979, known from New Caledonia and a few neighbouring islands.

Résumé [+] [-]There have been comparatively few large-scale studies on spatial genetic structure of bathyal sea floor fauna, despite the importance of these data to the successful management of the world's oceans.We use a comparative analysis of mitochondrial DNA from five bathyal (200–3500m) species of brittle-stars (Ophiuroidea) to assess phylogeographic structure along an extensive (8000km) longitudinal gradient at temperate latitudes (28–561S) from south-west Australia(113°E) to seamounts east of New Zealand (175°W). We found no evidence of a genetic discontinuity between Australia and New Zealand,either across the temperate Tasman Sea or across the Southern Ocean between the South Tasman Rise and the Macquarie Ridge. However, there were latitudinal phylogeographical breaks between tropical, temperate and polar regions; longitudinal breaks across the eastern Indian Ocean; and a bathymetric break at approximately 1700m. Although there was limited regional structure in the frequency of haplotype distributions within the major clades, and no clade appeared to be strictly panmictic, the regional structure in general was not concordant with a simple isolation-by-distance model. Demographic structure varied with three clades having a simplified haplotype network, low effective population sizes and no evidence of significant population expansion, and two clades having a high diversity of haplotypes, relatively high effective population sizes and signs of recent population expansion. These results are discussed with respect to putative dispersal strategies. We hypothesise that the ‘brooding’ species produce both brooded young and pelagic larvae, allowing for both the maintenance of local populations and long-distance dispersal.

Résumé [+] [-]Squat lobsters have a worldwide distribution and are highly visible crustaceans living in a broad range of habitats. In this study, partial sequences of two mitochondrial DNA genes (16S rRNA and COI) and a nuclear gene (H3) were obtained for all but one of the known species of the shallow-water genera Sadayoshia (Munididae) and Lauriea, Macrothea and Triodonthea (Galatheidae). Lauriea siagiani appeared to be phylogenetically closer to Triodonthea and Macrothea than to other Lauriea species, suggesting the need for taxonomic re-evaluation of these taxa. All species of Sadayoshia formed a monophyletic group that would have diverged during the Paleogene (around 50 Mya). Our results support the hypothesis that the late Paleogene–Neogene transition was a period of rapid diversification for shallowwater species of both Galatheidae and Munididae in the Indo-Pacific region. This is probably related to high tectonic activity among the Eurasian, Philippine Sea, Indo-Australian and Pacific plates and corresponding changes in distribution of habitats and ocean currents during the late Paleogene. Finally, the tropical south-west Pacific province is identified as a major diversification centre for shallow-water squat lobsters, from where species dispersed to other Pacific and Indian Ocean regions.

Résumé [+] [-]Understanding why some groups of organisms are more diverse than others is a central goal in macroevolution. Evolvability, or lineages' intrinsic capacity 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 venom 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, 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 whether or not we detected a signal depended on the dataset and the method. If our results remain true with increased sampling in future studies, they suggest that the rapid evolution of Conidae venom may cause other factors to become more critical to diversification, such as ecological opportunity or traits that promote isolation among lineages.

Résumé [+] [-]Identification of taxonomical units underpins most biological endeavours ranging from accurate biodiversity estimates to the effective management of sustainably harvested, protected or endangered species. Successful species identification is now frequently based on a combination of approaches including morphometrics and DNA markers. Sequencing of the mitochondrial COI gene is an established methodology with an international campaign directed at barcoding all fishes. We employed COI sequencing alongside traditional taxonomic identification methods and uncovered instances of deep intraspecific genetic divergences among flathead species. Sixty-five operational taxonomic units (OTUs) were observed across the Indo-West Pacific from just 48 currently recognized species. The most comprehensively sampled taxon, Platycephalus indicus, exhibited the highest levels of genetic diversity with eight lineages separated by up to 16.37% genetic distance. Our results clearly indicate a thorough reappraisal of the current taxonomy of P. indicus (and its three junior synonyms) is warranted in conjunction with detailed taxonomic work on the other additional Platycephalidae OTUs detected by DNA barcoding.

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.

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

Roux M., Eléaume M., Hemery L.G. & Améziane N. 2013. When morphology meets molecular data in crinoid phylogeny: a challenge. Cahiers de Biologie marine 54: 541-548
Résumé [+] [-]The extant crinoid fauna results from more than 485 Myr of evolution (from Early Ordovician). Detailed morphological studies on extant crinoids document large intraspecific variations, strong changes through ontogeny with various mosaics of heterochronic development, and adaptive characters which depend on environment, mainly hydrodynamics and food supply. The importance of paedomorphy and morphological convergences (homoplasies) in crinoid evolution is confirmed by studies using DNA markers, and makes difficult the use of cladistic methods of phylogenetic reconstructions. Many clades of extant crinoids based on external skeleton morphology are polyphyletic. Using the hyocrinids and a recent extensive molecular phylogeny of the extant crinoids, we show that the molecular approach, when coupled with detailed ontogenetic analyses on a large sample of specimens and taxa, may help understand the evolutionnary trends within a given group of organisms. Purely molecular or phenotypic analyses produce contrasting results because these analyses work at scales that are separated by a strong gap. We propose a deep reappraisal of the relationships between extant and fossil taxa using the concept of onto phylogeny which rejects the classical separation between ontogeny and phylogeny and argues that natural selection acts at every level of integration of the organism from DNA, cells, tissues, to the individuals and populations.

Résumé [+] [-]A revision of the genus Parviturbo Pilsbry & McGinty, 1945, distributed in the Atlantic Ocean, the American Pacific, and the Tropical South Pacific, is presented for the first time. In total 33 species were studied, of which 12 were already known (5 in the Eastern Atlantic, 5 in the Western Atlantic, and 2 in the American Pacific); 20 more are described as new species (4 in the Eastern Atlantic, 12 in the Western Atlantic, and 4 in the Tropical South Pacific) and one more from the Mediterranean is presented without a name. We provide new data on the radula for Parviturbo insularis, and the morphology of the shell is described and illustrated for all the species using scanning electron microscopy. Data on their distribution and habitat are also provided, and their generic allocation is discussed. The presence of species Parviturbo in the Tropical Pacific is confirmed. The type material of several species (Parviturbo rehderi Pilsbry & McGinty, 1945, Cyclostrema granulum Dall, 1899 and Delphinula tuberculosa d’Orbigny, 1842 is illustrated and a lectotype is designated for the latter species. Parviturbo dibellai Buzzurro & Cecalupo, 2007 is excluded from the genus, and considered a junior synonym of Fossarus eutorniscus Melvill, 1918; the species is transferred to Vitrinellinae but without a definite generic assignment. The two known Recent species of Pseudorbis, a genus close to Parviturbo, are studied for comparison and the differences and similarities between these two genera are discussed.

Résumé [+] [-]The family Ammotheidae is the most diversified group of the class Pycnogonida, with 297 species described in 20 genera. Its monophyly and intergeneric relationships have been highly debated in previous studies. Here, we investigated the phylogeny of Ammotheidae using specimens from poorly studied areas. We sequenced the mitochondrial gene encoding the first subunit of cytochrome c oxidase (CO1) from 104 specimens. The complete nuclear 18S rRNA gene was sequenced from a selection of 80 taxa to provide further phylogenetic signal. The base composition in CO1 shows a higher heterogeneity in Ammotheidae than in other families, which may explain their apparent polyphyly in the CO1 tree. Although deeper nodes of the tree receive no statistical support, Ammotheidae was found to be monophyletic and divided into two clades, here defined as distinct subfamilies: Achelinae comprises the genera Achelia Hodge, 1864, Ammothella Verrill, 1900, Nymphopsis Haswell, 1884 and Tanystylum Miers, 1879; and Ammotheinae includes the genera Ammothea Leach, 1814, Acheliana Arnaud, 1971, Cilunculus Loman, 1908, Sericosura Fry & Hedgpeth, 1969 and also Teratonotum gen. nov., including so far only the type species Ammothella stauromata Child, 1982. The species Cilunculus gracilis Nakamura & Child, 1991 is reassigned to Ammothella, forming the binomen Ammothella gracilis (Nakamura & Child, 1991) comb. nov. Additional taxonomic re-arrangements are suggested for the genera Achelia, Acheliana, Ammothella and Cilunculus.

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

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

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

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.

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

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

Résumé [+] [-]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 [+] [-]Understanding how the extraordinary taxonomic and ecological diversity of cone snails (Caenogastropoda: Conidae) evolved requires a statistically robust phylogenetic framework, which thus far is not available. While recent molecular phylogenies have been able to distinguish several deep lineages within the family Conidae, including the genera Profundiconus, Californiconus, Conasprella, and Conus (and within this one, several subgenera), phylogenetic relationships among these genera remain elusive. Moreover, the possibility that additional deep lineages may exist within the family is open. Here, we reconstructed with probabilistic methods a molecular phylogeny of Conidae using the newly sequenced complete or nearly complete mitochondrial (mt) genomes of the following nine species that represent all main Conidae lineages and potentially new ones: Profundiconus teramachii, Californiconus californicus, Conasprella wakayamaensis, Lilliconus sagei, Pseudolilliconus traillii, Conus (Kalloconus) venulatus, Conus (Lautoconus) ventricosus, Conus (Lautoconus) hybridus, and Conus (Eugeniconus) nobilis. To test the monophyly of the family, we also sequenced the nearly complete mt genomes of the following three species representing closely related conoidean families: Benthomangelia sp. (Mangeliidae), Tomopleura sp. (Borsoniidae), and Glyphostoma sp. (Clathurellidae). All newly sequenced conoidean mt genomes shared a relatively constant gene order with rearrangements limited to tRNA genes. The reconstructed phylogeny recovered with high statistical support the monophyly of Conidae and phylogenetic relationships within the family. The genus Profundiconus was placed as sister to the remaining genera. Within these, a clade including Californiconus and Lilliconus + Pseudolilliconus was the sister group of Conasprella to the exclusion of Conus. The phylogeny included a new lineage whose relative phylogenetic position was unknown (Lilliconus) and uncovered thus far hidden diversity within the family (Pseudolilliconus). Moreover, reconstructed phylogenetic relationships allowed inferring that the peculiar diet of Californiconus based on worms, mollusks, crustaceans and fish is derived, and reinforce the hypothesis that the ancestor of Conidae was a worm hunter. A chronogram was reconstructed under an uncorrelated relaxed molecular clock, which dated the origin of the family shortly after the Cretaceous-Tertiary boundary (about 59 million years ago) and the divergence among main lineages during the Paleocene and the Eocene (56–30 million years ago).

Résumé [+] [-]The commercial deep-sea penaeid shrimp genus Parapenaeus contains 15 species, three subspecies and two forms in the Indo-West Pacific and the Atlantic. Novel nucleotide sequence data from five different genes (COI, 16S, 12S, NaK and PEPCK) were collected to estimate phylogenetic relationships and taxonomic status amongst all but one subspecies in this genus. The phylogenetic results only support two of the four species groups previously proposed for this genus and indicate an evolution direction of the genital organs from simple to complex. The present results suggest that Parapenaeus originated in the shallow waters of the West Pacific with subsequent migration to the deep sea and the Atlantic. The molecular data reveal that there was probably misidentification of females between Parapenaeus australiensis and Parapenaeus ruberoculatus, with females previously assigned as P. australiensis likely being the females of P. ruberoculatus, while material identified as P. australiensis forma nodosa being the true P. australiensis females. On the other hand, Parapenaeus longipes forma denticulata truly represents a variation of the same species, while the subspecies Parapenaeus fissuroides indicus warrants a specific rank.
