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
Abstract [+] [-]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.

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
Abstract [+] [-]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.

Ashrafi H., Sari A. & Naderloo R. 2020. A new sponge-dwelling species of Synalpheus Spence Bate, 1888 (Decapoda: Caridea: Alpheidae) from the Persian Gulf. Zootaxa 4861(3): 338-348. DOI:10.11646/zootaxa.4861.3.2
Abstract [+] [-]The present study is based on material collected in the intertidal and shallow subtidal areas of two Islands in the Persian Gulf, Abu-Musa and Larak. The new species, Synalpheus pentaspinosus n. sp., is closely related to S. quinquedens Tattersall, 1921. These two species share a very characteristic, sixth pleonite armed posteriorly with five stout sharp teeth, a feature unique within the genus. The color of ovaries or freshly laid eggs, red-orange in S. pentaspinosus n. sp. vs. green in S. quinquedens, is the most obvious character, by which the new species may be distinguished from S. quinquedens in the field. In addition, the two species can be separated by two characters on the dactylus of the minor cheliped. In the new species, the dactylus is furnished with two prominent rows of setae, one dorsally and one mesially, and has a small concavity on the cutting edge, contrasting to only one mesial row of setae and no obvious concavity in S. quinquedens.

Abstract [+] [-]The present study focuses on shrimps belonging to the genus Lysmata Risso, 1816, collected from Madagascar during the Atimo Vatae expedition carried out in 2010. Lysmata malagasy sp. nov. is a new species belonging to the clade named “long accessory ramous” or “cosmopolitan” in previous phylogenetic studies. The new species can be distinguished from the only two other representatives of this group in the Indo-west Pacific, L. ternatensis De Man, 1902, and L. trisetacea (Heller, 1861), by the accessory ramus of the lateral antennular flagellum consisting of four elongated articles. Lysmata lipkei Okuno & Fiedler, 2010 is reported here from Madagascar with a remarkable extension of its known range after its original description from Japan. This species has also been reported from Singapore and, as alien species, from Brazil. Lastly, L. kuekenthali De Man, 1902 known from numerous localities in the Indo-West Pacific biogeographic area, is reported for the first time from Madagascar. Results of the present morphological and molecular analyses suggest that L. hochi Baeza & Anker, 2008 from the Caribbean Sea is a synonym of the Indo-West Pacific L. kuekenthali, and thus the latter species is alien in the western Atlantic.

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

Phylogenetic relationships of Gelidiella (Gelidiales, Rhodophyta) from Madagascar with a Description of Gelidiella incrassata sp. nov. Cryptogamie, Algologie 36(2): 219-237. DOI:10.7872/crya.v36.iss2.2015.219
Abstract [+] [-]We evaluated the relationships among species in the genus Gelidiella using 47 rbcL and 29 COI sequences, including those from 18 specimens collected in Madagascar. Molecular analyisis revealed the presence of three major lineages among Magalasy Gelidiella which were assigned, based on morpho-anatomical observation, to Gelidiella acerosa, G. ligulata and a so far not described species for which we here proposed the name G. incrassata. Both molecular and morphological data demonstrated the presence of three species in Madagascar: the G. acerosa complex, G. ligulata, and G. incrassata sp. nov., described here. Gelidiella incrassata was collected on small gravel from the intertidal down to a depth of 14 m on the southeast coast of Madagascar. It is distinguished by its large size (up to 7 cm), opposite to alternate ramuli, thick-walled cortical and medullary cells, and stalked tetrasporangial stichidia with irregular arrangement of tetrasporangia. Phylogenetic analyses of rbcL and COI sequences revealed the sister relationship between G. incrassata and G. fanii from southeast Asia and Hawaii. Gelidiella acerosa comprised three genetic groups in Madagascar, each being genetically distinct (pairwise distances, 4.9–8.3% for COI and 1.2–2.3% for rbcL). Further sampling of G. acerosa is needed before taxonomic revisions can be proposed. The distribution of G. ligulata is expanded to include the southwest Indian Ocean.

Abstract [+] [-]We analyzed both mitochondrial cox1 and plastid rbcL sequences from specimens of Pterocladiella from Madagascar and compared their morphologies with previously described species in the genus. Both molecular and morphological datasets demonstrated the presence of five species in Madagascar: P. australafricanensis, P. bartlettii, P. caerulescens, and two new species, P. feldmannii and P. hamelii, described here. Pterocladiella feldmannii is distinguished by plants with a size of about 6 cm with narrow axes and opposite to irregular branches, rhizines congested in medulla, tetrasporangial branchlets constricted at base of branches, tetrasporangial sori without sterile margins, and irregular arrangement of tetrasporangia. Pterocladiella hamelii is characterized by plants with a size of about 3 cm with flattened and thin erect axes and irregular branches, radial arrangement of subapical cells at tips of main axes, tetrasporangial sori with sterile margins and horizontal to irregular arrangement of tetrasporangia. Phylogenetic analyses based on cox1 and rbcL sequences revealed the sister relationship between P. feldmannii and P. hamelii, and their distant relationships to P. australafricanensis, P. bartlettii, and P. caerulescens. The Madagascan Pterocladiella is composed of two geographical elements: Madagascan endemic (P. feldmannii and P. hamelii) and species with wide distributions (P. australafricanensis, P. bartlettii and P. caerulescens).

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
Abstract [+] [-]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.

Abstract [+] [-]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.

Abstract [+] [-]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.

Abstract [+] [-]Material, mostly deep-water, belonging to eight families of brachyuran crabs are listed from the MAINBAZA, MIRIKI, and ATIMO VATAE expeditions to the Mozambique Channel and northwestern and southern Madagascar. A new species of Ethusa Roux, 1830 (Ethusidae), unique for its vivid colouration and collection in shallow water 13-22 m deep, is described from southern Madagascar. Sphenomerides trapezoides (Wood-Mason & Alcock, 1891) (Trapeziidae) is for the first time recorded from a host, a sponge, and the presence of mucus-gathering setae are for the first time demonstrated in this rarely collected species. A neotype for Dorippe sexdentata Stimpson, 1858 (Ethusidae) is designated to stabilise the taxonomy of the species. The male and the vulva of Ethusa machaera Castro, 2005, and the vulva of E. sexdentata (Stimpson, 1858) are described for the first time. Five species are new records for Madagascar: Crossotonotus spinipes (De Man, 1888) (Crossotonotidae); Carcinoplax ischurodous (Stebbing, 1923), Goneplax clevai Guinot & Castro, 2007, and Ommatocarcinus pulcher Barnard, 1950 (Goneplacidae); and Pseudopalicus sexlobatus (Kensley, 1969) (Palicidae); while Ethusina somalica (Doflein, 1904) (Ethusidae) is a new record for the southwestern Indian Ocean.

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

Dumoulin kervran D. 2012. Comment devient-on un coquillage scientifique ?. Techniques & Culture. Revue semestrielle d’anthropologie des techniques 59: 182–205
Abstract [+] [-]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.

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

Abstract [+] [-]Background: Planaxis sulcatus has been touted as a textbook example of poecilogony, with members of this wideranging Indo-Pacific marine gastropod said to produce free-swimming veligers as well as brooded juveniles. A recent paper by Wiggering et al. (BMC Evol Biol 20:76, 2020) assessed a mitochondrial gene phylogeny based on partial COI and 16S rRNA sequences for 31 individuals supplemented by observations from the brood pouch of 64 mostly unsequenced individuals. ABGD and bGYMC supported three reciprocally monophyletic clades, with two distributed in the Indo-Pacific, and one restricted to the northern Indian Ocean and Red Sea. Given an apparent lack of correlation between clade membership and morphological differentiation or mode of development, the reported 3.08% maximum K2P model-corrected genetic divergence in COI among all specimens was concluded to represent population structuring. Hence, the hypothesis that phylogenetic structure is evidence of cryptic species was rejected and P. sulcatus was concluded to represent a case of geographic poecilogony. Results: Our goal was to reassess the case for poecilogony in Planaxis sulcatus with a larger molecular dataset and expanded geographic coverage. We sequenced an additional 55 individuals and included published and unpublished sequence data from other sources, including from Wiggering et al. Our dataset comprised 108 individuals (88 COI, 81 16S rRNA) and included nine countries unrepresented in the previous study. The expanded molecular dataset yielded a maximum K2P model-corrected genetic divergence among all sequenced specimens of 12.09%. The value of 3.08% erroneously reported by Wiggering et al. is the prior maximal distance value that yields a single-species partition in ABGD, and not the maximum K2P intraspecific divergence that can be calculated for the dataset. The bGMYC analysis recognized between two and six subdivisions, while the best-scoring ASAP partitions recognized two, four, or five subdivisions, not all of which were robustly supported in Bayesian and maximum likelihood phylogenetic analyses of the concatenated and single gene datasets. These hypotheses yielded maximum intra-clade genetic distances in COI of 2.56–6.19%, which are more consistent with hypothesized species-level thresholds for marine caenogastropods. Conclusions: Based on our analyses of a more comprehensive dataset, we conclude that the evidence marshalled by Wiggering et al. in support of Planaxis sulcatus comprising a single widespread, highly variable species with geographic poecilogony is unconvincing and requires further investigation in an integrative taxonomic framework.

Abstract [+] [-]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.

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

Abstract [+] [-]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.

Abstract [+] [-]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.

Abstract [+] [-]Marginelliform gastropods are a heterogeneous and diverse group of molluscs encompassing over 1,600 living species, among which are the smallest known neogastropods. The relationships of marginelliform gastropods within the order Neogastropoda are controversial, and the monophyly of the two marginelliform families the Marginellidae J. Fleming, 1828 and the Cystiscidae Stimpson, 1865, remains unconfirmed. DNA sequence data have never been used to assess the relationships of the marginelliform gastropods, making this group the only major branch missing in our current understanding of the neogastropod tree of life. Here we report results of the first multilocus phylogenetic analysis of marginelliform gastropods, which is based on a dataset comprising 63 species (20 genera) of Marginellidae and Cystiscidae, and a wide range of neogastropod lineages. The Marginellidae and Cystiscidae form a moderately supported clade that is sister to the family Volutidae. Marginellona gigas appears to be sister to all other marginelliforms. The subfamily Marginellinae was recovered as a well-supported clade, and good resolution of this part of the tree makes it possible to propose amendments to the family-level classification of the group. The relationship between Granulina and other marginelliforms could not be resolved and requires further study. Due to poor resolution of basal relationships within the Marginellidae–Cystiscidae clade, the monophyly of the Cystiscidae was neither confirmed nor convincingly rejected. The shell morphology of most marginellid and cystiscid genera is taxonomically not very informative but, nevertheless, of the traditionally recognized genera only Gibberula and Dentimargo were shown to be polyphyletic. Although a comprehensive systematic revision of the group requires more extensive taxonomic sampling (e.g. with better representation of the type species of nominal genus-group names), our results support the superfamily Volutoidea, comprising four families (Volutidae, Cystiscidae, Marginellidae and Marginellonidae), with the placement of the Granulinidae uncertain for the time being.

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

Abstract [+] [-]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.

Abstract [+] [-]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.

Abstract [+] [-]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.

Abstract [+] [-]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.

Hallan A., Criscione F., Fedosov A. & Puillandre N. 2021. Few and far apart: integrative taxonomy of Australian species of Gladiobela and Pagodibela (Conoidea : Raphitomidae) reveals patterns of wide distributions and low abundance. Invertebrate Systematics. DOI:10.1071/IS20017
Abstract [+] [-]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.

Abstract [+] [-]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.

Abstract [+] [-]Several species of palaemonid shrimps are known to act as fish-cleaning symbionts, with cleaning interactions ranging from dedicated (obligate) to facultative. We confirmed five evolutionarily independent origins of fish cleaning symbioses within the family Palaemonidae based on a phylogenetic analysis and the ancestral state reconstruction of 68 species, including 13 fish-cleaners from the genera Ancylomenes, Brachycarpus, Palaemon, Periclimenes, and Urocaridella. We focus in particular on two distantly related lineages of fish cleaning shrimps with allopatric distributions, the Indo-West Pacific Ancylomenes and the western Atlantic monophyletic Ancylomenes/Periclimenes group, which exhibit striking similarities in morphology, colouration and complex behaviour. Specifically, representatives of both lineages are similar in: (1) the general body shape and colour pattern; (2) the utilization of sea anemones as conspicuous cleaning stations; and (3) the use of sideways body swaying to visually promote their bright colour spots in order to attract fish clients. Such morphological, ecological and ethological convergences are apparently due to adaptations to fish cleaning linked to the establishment of similar modes of communication with fish clients in these species.

Abstract [+] [-]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.

Huang Y.H. & Shih H.T. 2021. Diversity in the Taiwanese Swimming Crabs (Crustacea: Brachyura: Portunidae) Estimated through DNA Barcodes, with Descriptions of 14 New Records. Zoological Studies: 45
Abstract [+] [-]The swimming crabs (family Portunidae) are distributed worldwide and commonly inhabit estuaries, mangroves, reefs, shallow and the deep sea. Previously, 75 species and 19 genera in this family were known to Taiwan. Our study examined specimens in Taiwanese waters, including the islands, collected between 2016 and 2020 or deposited in museums. Through the cytochrome oxidase subunit I DNA barcode marker and morphological examination, 71 species were identified. The minimum interspecific distances were greater than 4.09%, except in two unresolved groups: Charybdis miles (De Haan, 1835) and Ch. sagamiensis Parisi, 1916, as well as Thranita pelsarti (Montgomery, 1931) and Thr. prymna (Herbst, 1803). In addition, 14 species belonging to nine genera were confirmed as new records to Taiwan, viz. Carupa ohashii Takeda, 1993, Lupocyclus inaequalis (Walker, 1887), Luu. tugelae Barnard, 1950, Lupocycloporus minutus (Shen, 1937), Monomia gladiator (Fabricius, 1798), M. lucida Koch & Ďuriš, 2018, Podophthalmus minabensis Sakai, 1961, Thalamita gatavakensis Nobili, 1906, Tha. spinifera Borradaile, 1902, Thalamitoides quadridens A. Milne-Edwards, 1869, Tho. tridens A. Milne-Edwards, 1869, Thr. cerasma (Wee & Ng, 1995), Thr. coeruleipes (Hombron & Jacquinot, 1846) and Xiphonectes tuberculosus (A. Milne-Edwards, 1861). This study thus raises the total number of Portunidae species in Taiwan to 89.

Thesenew specimens represent the first record of the species from Madagascar and the southern hemisphere. Comparisons in meristic and morphometric characters with the four type specimens from Oman, as well as with the five other species in the subgenus Sillago, allowed their clear identification using the following combination of characters: small head (28.6-30.1% SL), 35-6 total vertebrae, fused or narrowly separated first and second hypurals, fused third and fourth hypurals, and 9-11 dusky spots on midline of body.

Kantor Y., Fedosov A.E., Puillandre N., Bonillo C. & Bouchet P. 2017. Returning to the roots: morphology, molecular phylogeny and classification of the Olivoidea (Gastropoda: Neogastropoda). Zoological Journal of the Linnean Society 180: 493-541. DOI:10.1093/zoolinnean/zlw003
Abstract [+] [-]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).

Abstract [+] [-]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.

Abstract [+] [-]According to a recent taxonomic revision by Kantor et al. (2001), the neogastropod genus Exilia Conrad, 1860, comprises ten mostly rare species that live at depths between 200 and 2000 m. Adult Exilia measure between 30 and 90 mm in shell length, and the genus is mostly represented in museum collections by empty shells. The abundance of this genus is low in the wild, but recent expeditions organized by the Muséum national d’Histoire naturelle have yielded several dozen specimens. These new collections include samples preserved for molecular studies. Here, we present the results of the first molecular systematic study of Exilia. Our aim was to investigate the species limits proposed by Kantor et al. (2001) on the basis of shell and anatomical characters. Analysis of DNA sequence data for the cytochrome c oxidase I gene suggests that Exilia hilgendorfi, previously considered to be a single, polymorphic and broadly distributed species, is a complex of at least six species (four of which we sequenced). Two of these species, Exilia cognata n. sp. and E. fedosovi n. sp., are described as new to science. Exilia gracilior, E. claydoni and E. prellei are resurrected from the synonymy of Exilia hilgendorfi; of these three, only the last was sequenced. Exilia vagrans is a welldefined taxon, but our molecular systematic data shows that it consists of two distinct species, which occur sympatrically off Taiwan and are strikingly similar in shell and radular morphology; due to the absence of DNA sequence data from the type locality of E. vagrans (Vanuatu), it is unclear to which of these two species the name would apply. Exilia karukera n. sp., which is conchologically very similar to E. vagrans, was discovered off Guadeloupe, represents the first record of the genus from the Atlantic. For E. elegans, which was previously known only from a single shell, we provide new data including new distributional records (South Africa and the Mozambique Channel), details of the radula and DNA sequence data.

Abstract [+] [-]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.

Abstract [+] [-]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).

Abstract [+] [-]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.

Abstract [+] [-]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.

Deep Sea Research Part I: Oceanographic Research Papers 160: 103256. DOI:10.1016/j.dsr.2020.103256
Abstract [+] [-]The abyssal and hadal Buccinoidea from the north-western Pacific formerly attributed to the genera Tacita and Calliloncha were analyzed for the first time using both multilocus molecular and morphological data. The results allow re-evaluation of the inter- and intrageneric variability of morphological characters and demonstrate that Tacita, Calliloncha and Paracalliloncha are synonyms of Bayerius, a genus widely distributed in the Pacific Ocean. In our reconstructed phylogeny the genus forms a maximally supported clade with Pararetifusus tenuis and Turrisipho dalli. At present, Bayerius includes 10 species, two of which are described herein as new to science, B. inflatus sp. nov. and B. nekrasovorum sp. nov. with one additional undescribed species represented in our material by a single specimen. The genus is reviewed, with the addition of new data on anatomy and distribution, based on newly obtained material. B. peruvianus is synonymized with B. zenkewitchi. Calliloncha nankaiensis together with Costaria crosnieri are attributed to a new genus, Warenius gen. nov., which clusters with several genera of Buccinoidea from biogenic substrata.

Abstract [+] [-]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.

Abstract [+] [-]Detailed study of the Monniot collection of copepods belonging to the family Notodelphyidae has revealed an extraordinary diversity of novel taxa. With rare exceptions notodelphyids live in association with ascidians and the Monniot collection was built up over several decades of field collecting and taxonomic research on the ascidian hosts by Drs Claude & Françoise Monniot (MNHN, Paris). This paper describes a total of 178 new species of notodelphyids from ascidian hosts and 37 new genera are established: Bathynotodelphys gen.nov., Pronotodelphys gen. nov., Ooishillgia gen. nov., Nobinerilla gen. nov., Notopygus gen. nov., Chelipygus gen. nov., Sympygus gen. nov., Vaoda gen. nov., Gosbia gen. nov., Pentachaetus gen. nov., Diceratus gen. nov., Prodoroixys gen. nov., Notoixys gen. nov., Borixys gen. nov., Cystixys gen. nov., Ammonixys gen. nov., Ctenixys gen. nov., Ademoixys gen. nov., Gallincola gen. nov., Scoliosoma gen. nov., Contoura gen. nov., Unimeria gen. nov., Mecodelphys gen. nov., Tubipedia gen. nov., Procampodelphys gen. nov., Janius gen. nov., Campodelphys gen. nov., Hamaticoxa gen. nov., Adrodelphys gen. nov., Phyllodelphys gen. nov., Lissodelphys gen. nov., Nodoscarus gen. nov., Diblastus gen. nov., Chilodelphys gen. nov., Scaridelphys gen. nov., Socotradelphys gen. nov., and Aplodelphys gen. nov. Prior to this study the Notodelphyidae comprised exactly 200 valid species classified in 46 genera, a mean species richness of 4.3 species per genus. After the addition of the new taxa described here, the family now comprises 378 species in 83 genera, a mean species richness of 4.6 species per genus. Generic diagnoses are provided for all genera represented in the collection and the availability of a wider range of taxa has allowed certain generic boundaries to be better defined, resulting in transfers of species between genera and the recognition of 16 new combinations. A further 51 existing species are also reported, and brief supplementary notes or full redescriptions are provided as appropriate.

Abstract [+] [-]A new species of portunid crab from the genus Cycloachelous Ward, 1942 is described from Vietnamese waters. Cycloachelous levigatus sp. nov. is morphologically most similar to C. orbitosinus (Rathbun, 1911), which was originally described from the syntype series collected from Western Pacific area (Cargados Carajos Islands, Amirante Islands, Seychelles) and C. octodentatus (Gordon, 1938) described from one single male from Singapore. There are differences in the sternal segments, third maxilliped, chela, abdomen and male gonopode shapes. The specific status of C. levigatus sp. nov. is also clearly supported by molecular data. Aside from a comparison of this new species with other known congeners, new photographs of syntypes of C. orbitosinus and the holotype of C. octodentatus are also provided.

Abstract [+] [-]Abstract The shrimp genera Ephyrina, Meningodora and Notostomus have an unusual carapace strengthened with carinae and a half-serrated mandible, which may suggest a possible monophyly of this group. Here we test this hypothesis and present the first phylogenetic study of these genera based on 95 morphological characters (all valid species coded) and six molecular markers (71% of valid species sequenced). Representatives of all genera of Oplophoridae (sister to Acanthephyridae) were outgroups, 32 species belonging to all genera and potentially different clades of Acanthephyridae were ingroups. Both morphological and molecular analyses retrieve trees with similar topology. Our results reject the hypothesis of a clade formed by Ephyrina + Meningodora + Notostomus. We show that Ephyrina and Notostomus are monophyletic, both on morphological and on molecular trees, Meningodora gains support only on morphological trees. Evolutionary traits in the Ephyrina and Meningodora + Notostomus clades are different. Synapomorphies are mostly linked to adaptations to forward motion in Ephyrina (oar-like meri and ischia of pereopods, stempost-like rostrum) and to progressive strengthening of the carapace and pleon in Meningodora and Notostomus (net of sharp carinae). Unusual mandibles evolved in the clades independently and represent convergent adaptations to feeding on gelatinous organisms.

Speciation pattern of the horned ghost crab Ocypode ceratophthalmus (Pallas, 1772): An evaluation of the drivers of Indo-Pacific marine biodiversity using a widely distributed species. Journal of Biogeography 45(12): 2658-2668. DOI:10.1111/jbi.13443
Abstract [+] [-]Aim: The high species richness of the Indo‐Australian Archipelago (IAA) marine biodiversity hotspot has been attributed to three competing hypotheses: Centre of Origin/Centre of Overlap/Centre of Accumulation. While most phylogeographic studies testing these hypotheses have focused on marine fishes, we provide a new perspective on this evolutionary important question by examining the population genetics of the horned ghost crab Ocypode ceratophthalmus sensu lato (Ocypodidae) whose distribution spans the entire Indo‐Pacific and contains at least two colour morphs.

Abstract [+] [-]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.

Abstract [+] [-]Modern goniasterids are the most numerous of living asteroids in terms of described genera and species and they have important ecological roles from shallow to deep-water marine habitats. Recent MNHN expeditions and historical collections in the USNM have resulted in the discovery of 18 new species, three new genera and multiple new occurrence records from the western Indian Ocean region including Madagascar, Glorioso and Mayotte islands, Walters Shoal, South Africa, and Somalia. This report provides the first significant contribution to knowledge of deep-sea Asteroidea from the Indian Ocean since the late 20th Century. Several deep-sea species, previously known from the North Pacific are now reported from the western Indian Ocean. Gut contents from Stellaster and Ogmaster indicate deposit feeding. Feeding modes of this and other deep-sea species are discussed. Comments are made on fossil members of included taxa. A checklist of Indian Ocean Goniasteridae is also included.

Abstract [+] [-]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.

DOI:10.1093/sysbio/syz059
Abstract [+] [-]Abstract How species diversification occurs remains an unanswered question in predatory marine invertebrates, such as sea snails of the family Terebridae. However, the anatomical disparity found throughput the Terebridae provides a unique perspective for investigating diversification patterns in venomous predators. In this study, a new dated molecular phylogeny of the Terebridae is used as a framework for investigating diversification of the family through time, and for testing the putative role of intrinsic and extrinsic traits, such as shell size, larval ecology, bathymetric distribution, and anatomical features of the venom apparatus, as drivers of terebrid species diversification. Macroevolutionary analysis revealed that when diversification rates do not vary across Terebridae clades, the whole family has been increasing its global diversification rate since 25 Ma. We recovered evidence for a concurrent increase in diversification of depth ranges, while shell size appeared to have undergone a fast divergence early in terebrid evolutionary history. Our data also confirm that planktotrophy is the ancestral larval ecology in terebrids, and evolutionary modeling highlighted that shell size is linked to larval ecology of the Terebridae, with species with long-living pelagic larvae tending to be larger and have a broader size range than lecithotrophic species. Although we recovered patterns of size and depth trait diversification through time and across clades, the presence or absence of a venom gland (VG) did not appear to have impacted Terebridae diversification. Terebrids have lost their venom apparatus several times and we confirm that the loss of a VG happened in phylogenetically clustered terminal taxa and that reversal is extremely unlikely. Our findings suggest that environmental factors, and not venom, have had more influence on terebrid evolution.

Monniot F. 2012. Some ascidians from the southern coast of Madagascar collected during the “AtimoVatae” survey. Zootaxa 3197: 1-42
Abstract [+] [-]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).

Abstract [+] [-]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.

Abstract [+] [-]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.

Abstract [+] [-]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.

Abstract [+] [-]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.

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

Abstract [+] [-]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.

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
Abstract [+] [-]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.

Abstract [+] [-]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.

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

Abstract [+] [-]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.

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
Abstract [+] [-]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.

Abstract [+] [-]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.

Abstract [+] [-]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.

Abstract [+] [-]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.

Abstract [+] [-]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)

Molecular Phylogenetics and Evolution 137: 293-299. DOI:10.1016/j.ympev.2019.05.006
Abstract [+] [-]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.

Abstract [+] [-]Species identities of Goniobranchus nudibranchs with white bodies and various marginal bands have long been problematic. In this study, specimens of these Goniobranchus nudibranchs from the Philippines, Peninsular Malaysia, Japan, Papua New Guinea, and Madagascar were analyzed and molecular data were obtained in order to re-examine the relationships between species within this “white Goniobranchus with marginal bands” group. The analyses clearly recovered six species groups corresponding to the described species Goniobranchus albonares, G. preciosus, G. rubrocornutus, G. sinensis, and G. verrieri as well as one new species, G. fabulus Soong & Gosliner, sp. nov. Notably, G. preciosus, G. sinensis, G. rubrocornutus, G. verrieri, and G. fabulus Soong & Gosliner, sp. nov. exhibit color variation and polymorphism, suggesting that some aspects of color patterns (e.g., presence or absence of dorsal spots) may not always be useful in the identification of species in the “white Goniobranchus with marginal bands” group, whereas other features such as gill and rhinophore colors and the arrangement and colors of the mantle marginal bands are more diagnostic for each species.

Abstract [+] [-]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.

Abstract [+] [-]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.

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

Abstract [+] [-]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.

Abstract [+] [-]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.

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

Terryn Y.. The Duplicaria duplicata (Linnaeus, 1758)-complex (Gastropoda: Terebridae): Part II. The ‘Duplicaria lamarckii-complex’ with the description of seven new species. : 16
Abstract [+] [-]After having established the identity of Duplicaria duplicata (Linnaeus, 1758) and its historical synonyms Duplicaria lamarckii (Kiener, 1839), Duplicaria duplicatoides (Bartsch, 1923) and Duplicaria reevei (Deshayes, 1857) and having highlighted the possible identity of Duplicaria morbida (Reeve, 1860) and Duplicaria nadinae (Aubry, 2008) (see Part I), a number of morpho-species, close in shell morphology to D. lamarckii, were studied. The present study reveals an additional 7 previously undescribed species with similarities to D. lamarckii, rediscovers the enigmatic species D. morbida in the Red Sea and tentatively includes D. nadinae within this informal morphological grouping, called the ‘lamarckii-complex’ of the Indian Ocean.

Abstract [+] [-]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).

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

Abstract [+] [-]Long-branch attraction (LBA) is a well-known artifact in phylogenetic reconstruction. Sparse taxon sampling and extreme heterogeneity of evolutionary rates among lineages generate propitious situations for LBA, even defying probabilistic methods of phylogenetic inference. A clear example illustrating LBA challenges is the difficulty of reconstructing the deep gastropod phylogeny, particularly using mitochondrial (mt) genomes. Previous studies consistently obtained unorthodox phylogenetic relationships due to the LBA between the mitogenomes of patellogastropods (true limpets, represented only by Lottia digitalis), heterobranchs, and outgroup taxa. Here, we use the reconstruction of the gastropod mitogenomic phylogeny as a case exercise to test the effect of key methodological approaches proposed to counteract LBA, including the selection of slow-evolving representatives, the use of different outgroups, the application of site-heterogeneous evolutionary models, and the removal of fast-evolving sites. In this regard, we sequenced three new patellogastropod mt genomes, which displayed shorter branches than the one of Lottia as well as gene organizations more similar to that of the hypothetical gastropod ancestor. Phylogenetic analyses incorporating the mt genomes of Patella ferruginea, Patella vulgata, and Cellana radiata allowed eliminating the artificial clustering of Patellogastropoda and Heterobranchia that had prevailed in previous studies. Furthermore, the use of site-heterogeneous models with certain combinations of lineages within the outgroup allowed eliminating also the LBA between Heterobranchia and the outgroup, and recovering Apogastropoda (i.e., Caenogastropoda + Heterobranchia). Hence, for the first time, we were able to obtain a mitogenomic phylogeny of gastropods that is congruent with both morphological and nuclear datasets.

Abstract [+] [-]The mantis shrimp superfamily Squilloidea, with over 185 described species, is the largest superfamily in the crustacean order Stomatopoda. To date, phylogenetic relationships within this superfamily have been comprehensively analysed using morphological data, with six major generic groupings being recovered. Here, we infer the phylogeny of Squilloidea using a combined dataset comprising 75 somatic morphological characters and four molecular markers. Nodal support is low when the morphological and molecular datasets are analysed separately but improves substantially when combined in a total-evidence phylogenetic analysis. We obtain a well resolved and strongly supported phylogeny that is largely congruent with previous estimates except that the Anchisquilloides-group, rather than the Meiosquillagroup, is the earliest-branching lineage in Squilloidea. The splits among the Anchisquilloides- and Meiosquilla-groups are followed by those of the Clorida-, Harpiosquilla-, Squilla- and Oratosquilla-groups. Most of the generic groups are recovered as monophyletic, with the exception of the Squilla- and Oratosquilla-groups. However, many genera within the Oratosquilla-group are not recovered as monophyletic. Further exploration with more extensive molecular sampling will be needed to resolve relationships within the Oratosquilla-group and to investigate the adaptive radiation of squilloids. Overall, our results demonstrate the merit of combining morphological and molecular datasets for resolving phylogenetic relationships.

Abstract [+] [-]The deep sea is the largest biome on Earth and hosts the majority of as yet undescribed species; description of these may trigger a new mindset about evolution and function of characters. We describe and diagnose a new genus and species Sclerodora crosnieri sp. nov. belonging to the superfamily Oplophoroidea. We examined and coded 81 characters for morphological analyses and used four gene markers for molecular analyses involving the new taxon and representatives of all other genera of Oplophoroidea. Retrieved morphological and molecular trees were similar and suggested that the new genus is a sister group to Hymenodora and both form a clade sister to the rest of Acanthephyridae. We provide an amended key to all genera of Oplophoroidea. We found an unusual chelate structure on the dactyl of the fifth pereopod, tested and confirmed a hypothesis that this structure is common for the whole family Acanthephyridae. We suggest that this derived structure is linked to an active cleaning of branchia—a function associated with chelipeds in some other carid shrimps. Convergent chelate structures are likely efficient for cleaning branchia, whichever appendage is adapted for these functions. In Oplophoridae (sister to Acanthephyridae), cleaning function is carried out by well-developed epipods.

Abstract [+] [-]Adult female dajid isopods are ectoparasites found on carapaces, within marsupia, or rarely attached to the eyestalks or pereopods of crustacean hosts. We describe two new genera and species whose females exhibit a novel spheroid shape and envelope antennules of hosts: Akrophryxus milvus n. gen., n. sp. parasitizing Ethusa machaera Castro, 2005 (Madagascar, c. 900 m) and Telephryxus clypeus n. gen., n. sp. parasitizing Munidopsis crassa Smith, 1885 (Caribbean, c. 5000 m). Females of both species differ from other dajid species in their spheroid shape and a plate partially surrounding the host antennule; males are distinguished by reduction of pereopods. Females of A. milvus n. gen., n. sp. are distinguished from those of T. clypeus n. gen., n. sp. in possessing antennules and a triangular attachment plate with three holes (T. clypeus n. gen., n. sp. lacks antennules and the broad attachment plate has two medial holes). Males of A. milvus n. gen., n. sp. are distinguished from those of T. clypeus n. gen., n. sp. in having only six pairs of pereopods, rudimentary antennules, single segmented antennae, and pleon fused to pereomere 7 (T. clypeus n. gen., n. sp. with rudimentary seventh pair of pereopods, large single segmented antennules, two segmented antennae, and pleon distinct from pereomere 7). Pre-molt epicaridium larvae and cryptoniscus larvae of T. clypeus n. gen., n. sp. are described. We also describe Aegophila cappa n. sp. found on pereopods of the isopod Aegiochus symmetrica (Richardson, 1905) (Bering Sea, c. 650 m), distinguished from the type species of Aegophila Bresciani, 1966 by oostegite morphology of the female, form of the antennae, and shape of the pleon of males.

Abstract [+] [-]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.

Just the once will not hurt: DNA suggests species lumping over two oceans in deep-sea snails (Cryptogemma). Zoological Journal of the Linnean Society 190(2): 532-557. DOI:10.1093/zoolinnean/zlaa010
Abstract [+] [-]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.
