Ahyong S.T. & Ng P.K. 2017. East Asian Cymonomid Crabs (Crustacea: Brachyura). Zoological Studies 56(24): 1-20. DOI:10.6620/ZS.2017.56-24
Abstract [+] [-]Cymonomid crabs are small cryptic deep-water brachyurans occurring worldwide. Six species have been reported from East Asia: one from both Taiwan and Japan (C. andamanicus Alcock, 1905) and five from Japan only (C. curvirostris Sakai, 1965, C. japonicus Balss, 1922, C. sagamiensis Sakai, 1983, C. soela Ahyong and Brown, 2003, C. umitakae Takeda, 1981). Cymonomus curvirostris, C. japonicus, C. sagamiensis and C. umitakae were described from Japanese waters, but C. andamanicus and C. soela have much more distant type localities - the Andaman Sea and southeastern Australia, respectively. We review all previous records of Cymonomus from East Asia, describe two new species, and clarify the status of records of C. andamanicus and C. soela from the region. Records of C. andamanicus and C. soela from East Asia are referable to two new species occurring in both Taiwan and Japan. The identities of C. japonicus and C. sagamiensis are fixed by neotype selection; C. sagamiensis is made a junior objective synonym of C. umitakae. Six species of Cymonomus are now recorded from Japan, of which two also occur off Taiwan. We also report on cymonomids collected by Taiwanese research vessels in the South China Sea (Dongsha and Macclesfield Bank) of which four species were collected, including C. hakuhoae Takeda and Moosa, 1990, not previously found in Japan or Taiwan. A key to the species of Cymonomus from East Asia and the South China Sea is included.

Abstract [+] [-]Fourteen species of Recent brachiopods belonging to the genera Novocrania, Basiliola, Acanthobasiliola, Gryphus, Zygonaria, Terebratulina, Eucalathis, Laqueus, Frenulina, Annuloplatidia, Phaneropora, Dallina and Campages have been identified in the samples collected during the French–Taiwanese ZhongSha 2015 expedition to the South China Sea, West Pacific. Five species were already described from this region. The remaining species represent first records for the South China Sea, among them two species, Annuloplatidia curiosa and Phaneropora galatheae are recorded for the first time in the northern hemisphere.

Chang S.C. & Chan T.Y. 2019. On the clawed lobsters of the genus Nephropsis Wood-Mason, 1872 recently collected from deep-sea cruises off Taiwan and the South China Sea (Crustacea, Decapoda, Nephropidae). ZooKeys 833: 41-58. DOI:10.3897/zookeys.833.32837
Abstract [+] [-]Recent deep-sea cruises using Taiwanese research vessels off Taiwan and in the South China Sea yielded seven species of the clawed lobster genus Nephropsis Wood-Mason, 1872. Four species are new records for Taiwan (Nephropsis acanthura Macpherson, 1990, N. holthuisi Macpherson, 1993, N. serrata Macpherson, 1993, and N. suhmi Bate, 1888) and three species are new records of Dongsha (under the jurisdiction of Taiwan) in the South China Sea (N. ensirostris Alcock, 1901, N. stewarti Wood-Mason, 1872, and N. suhmi). Altogether, five and four species of this genus are now known from Taiwan and Dongsha, respectively. The diagnostic characters and coloration are illustrated for most, if not all, of these species.

Abstract [+] [-]Calyptogena” marissinica n. sp. is described from the Haima cold seep on the northwestern slope of the South China Sea, China, at depths of 1,372 m and 1,398 m. Phylogenetic reconstruction using the cytochrome oxidase c subunit I (COI) gene shows that it is sister to Calyptogena similaris but distinct from that species by a pairwise distance of 3.9%, larger than the average intraspecific variation within the genus Calyptogena sensu lato. Morphologically, the new species is distinguished from C. similaris in having a less elongate shell, with nearly straight ventral margin, and no apparent anterior lateral tooth.

Chen J.N., Samadi S. & Chen W.J. 2018. Rhodopsin gene evolution in early teleost fishes. PLOS ONE 13(11): e0206918. DOI:10.1371/journal.pone.0206918
Abstract [+] [-]Rhodopsin mediates an essential step in image capture and is tightly associated with visual adaptations of aquatic organisms, especially species that live in dim light environments (e.g., the deep sea). The rh1 gene encoding rhodopsin was formerly considered a singlecopy gene in genomes of vertebrates, but increasing exceptional cases have been found in teleost fish species. The main objective of this study was to determine to what extent the visual adaptation of teleosts might have been shaped by the duplication and loss of rh1 genes. For that purpose, homologous rh1/rh1-like sequences in genomes of ray-finned fishes from a wide taxonomic range were explored using a PCR-based method, data mining of public genetic/genomic databases, and subsequent phylogenomic analyses of the retrieved sequences. We show that a second copy of the fish-specific intron-less rh1 is present in the genomes of most anguillids (Elopomorpha), Hiodon alosoides (Osteoglossomorpha), and several clupeocephalan lineages. The phylogenetic analysis and comparisons of alternative scenarios for putative events of gene duplication and loss suggested that fish rh1 was likely duplicated twice during the early evolutionary history of teleosts, with one event coinciding with the hypothesized fish-specific genome duplication and the other in the common ancestor of the Clupeocephala. After these gene duplication events, duplicated genes were maintained in several teleost lineages, whereas some were secondarily lost in specific lineages. Alternative evolutionary schemes of rh1 and comparison with previous studies of gene evolution are also reviewed.

Criscione F., Hallan A., Fedosov A. & Puillandre N. 2021. Deep Downunder: Integrative taxonomy of Austrobela , Spergo , Theta and Austrotheta (Gastropoda: Conoidea: Raphitomidae) from the deep sea of Australia. Journal of Zoological Systematics and Evolutionary Research 59(8): 1718-1753. DOI:10.1111/jzs.12512
Abstract [+] [-]Recent sampling efforts in the deep seas of southern and eastern Australia have generated a wealth of DNA-suitable material of neogastropods of the family Raphitomidae. Based on this material, a molecular phylogeny of the family has revealed a considerable amount of genus and species level lineages previously unknown to science. These taxa are now the focus of current integrative taxonomic research. As part of this ongoing investigation, this study focuses on the genera Austrobela, Austrotheta (both Criscione, Hallan, Puillandre & Fedosov, 2020), Spergo Dall, 1895 and Theta Clarke, 1959. We subjected a comprehensive mitochondrial DNA dataset of representative deep-sea raphitomids to Automatic Barcode Gap Discovery, which recognized 24 primary species hypotheses (PSHs). Following additional evaluation of shell and radular features, as well as examination of geographic and bathymetric ranges, 18 of these PSHs were converted to secondary species hypotheses (SSHs). Based on the evidence available, the most likely speciation mechanisms involved were evaluated for each pair of sister SSHs, including niche partitioning. Eleven SSHs were recognized as new and their systematic descriptions are provided herein. Of these, four were attributed to Austrobela, one to Austrotheta, four to Spergo and two to Theta. While all new species are endemic to Australian waters, other species studied herein exhibit wide Indo-Pacific distributions, adding to the growing body of evidence suggesting that wide geographic ranges in deep-sea Raphitomidae are more common than previously assumed.

Fassio G., Russini V., Buge B., Schiaparelli S., Modica M.V., Bouchet P. & Oliverio M. 2020. High cryptic diversity in the kleptoparasitic genus Hyalorisia Dall, 1889 (Littorinimorpha: Capulidae) with the description of nine new species from the Indo-West Pacific. Journal of Molluscan Studies: 401-421. DOI:10.1093/mollus/eyaa028
Abstract [+] [-]Species in the family Capulidae (Littorinimorpha: Capuloidea) display a wide range of shell morphologies. Several species are known to live in association with other benthic invertebrates—mostly bivalves and sabellid worms, but also other gastropods—and are believed to be kleptoparasitic filter feeders that take advantage of the water current produced by the host. This peculiar trophic ecology, implying a sedentary lifestyle, has resulted in highly convergent shell forms. This is particularly true for the genus Hyalorisia Dall, 1889, which occurs in deep water in the Caribbean and Indo-West Pacific provinces, with two nominal species recognized so far. Combining morphological, ecological and molecular data, we assessed the diversity of the genus, its phylogenetic position inside the family and its association with its bivalve host, the genus Propeamussium de Gregorio, 1884 (Pectinoidea), resulting in the description of nine new cryptic species. When sympatric, species of Hyalorisia are associated with different host species, but the same species of Propeamussium may be the host of several allopatric species of Hyalorisia.

Fedosov A.E., Malcolm G., Terryn Y., Gorson J., Modica M.V., Holford M. & Puillandre N. 2019. Phylogenetic classification of the family Terebridae (Neogastropoda: Conoidea). Journal of Molluscan Studies 85(4): 359-388. DOI:10.1093/mollus/eyz004
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.

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 [+] [-]In the course of preparation of a new molecular phylogeny of Conoidea based on exon-capture some new species and species with notable morphology were revealed. The taxonomy of these species is discussed and the radula of most of them illustrated for the first time. New genera are described: Comispira gen. nov. (Cochlespiridae), type species Leucosyrinx mai Li et Li, 2008; Pagodaturris gen. nov. (Clavatulidae), type species Pleurotoma molengraaffi Tesch, 1915. New species described: Comispira compta gen. et sp. nov., Sibogasyrinx sangeri sp. nov. (both Cochlespiridae), Pagodaturris philippinensis gen. et sp. nov. (Clavatulidae), Horaiclavus micans sp. nov., Iwaoa invenusta sp. nov. (both Horaiclavidae), Lucerapex cracens sp. nov., Lucerapex laevicarinatus sp. nov. (Turridae), Heteroturris kanacospira sp. nov. (Borsoniidae). Epideira Hedley, 1918 is reallocated from Pseudomelatomidae to Horaiclavidae. The radulae of Kuroshioturris nipponica (Shuto, 1961) (Turridae), Leucosyrinx verrillii (Dall, 1881), and Leucosyrinx luzonica (Powell, 1969) comb. nov. are illustrated for the first time.

Abstract [+] [-]This contribution provides novel information on the anatomy, radula and phylogeny of several species of Phaenomenella Fraussen & Hadorn, 2006, a genus of Buccinoidea Rafinesque, 1815 with unclear affinities. Molecular phylogenetic analysis based on sequences of mitochondrial COI and nuclear 28S rRNA genes of different representatives of Buccinoidea revealed close relationships of Phaenomenella with Siphonalia A. Adams, 1863 both taxa forming a clade with maximal support. The anatomy of two species of the latter genus was examined for the first time for comparative purposes. The subfamily Siphonaliinae Finlay, 1928 was erected for several Recent and fossil genera of Southern Hemisphere Buccinidae Rafinesque, 1815, and is still recognized by current taxonomists (Bouchet et al. 2017). Species of all Recent genera of Siphonaliinae were included in our analysis and the monophyly of the subfamily Siphonaliinae in its original scope is rejected. Molecular and morphological data revealed two still unnamed species of Phaenomenella from the lower bathyal zone of the South China Sea. These species, Phaenomenella nicoi n. sp. and P. samadiae n. sp. are described in the present study.

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.

Review of the abysso-hadal genus Bayerius (Gastropoda: Neogastropoda: Buccinidae) from the North-West Pacific, with description of two new 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.

Kantor Y.I., Castelin M., Fedosov A. & Bouchet P. 2020. The Indo-Pacific Amalda (Neogastropoda, Olivoidea, Ancillariidae) revisited with molecular data, with special emphasis on New Caledonia. European Journal of Taxonomy(706): 1-52. DOI:10.5852/ejt.2020.706
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 [+] [-]With 11 species, the genus Chelidoperca is a small group of teleost fishes belonging to the Serranidae. They are bottom-dwelling fishes living on continental shelves/slopes in offshore areas or on remote seamounts/banks at depths ranging from around 40–400m mostly in the tropical Indo-West Pacific. Over the past few years, efforts have been made to resolve the taxonomy of Chelidoperca, and subsequently four new species were described. However, these recent advances were made with a traditional approach (i.e., morphology) and limited examinable materials, usually preserved specimens, from ichthyological collections. Further investigations are still needed to address the gaps in our knowledge about their diversity, phylogeny, and biogeography. In this study, we collected 65 new samples, mainly during eight biodiversity expeditions carried out between 2007 and 2016 in the West Pacific under the Tropical Deep-Sea Benthos program. Specimens were photographed after collection to record fresh color patterns, which are essential for species diagnosis. Our analytical approach includes state-of-the-art DNA-based methods for species delimitation. The combined evidence from both molecular and morphological examinations, as well as other information such as geography, is used to test species validity. This reveals 15 species, including six new ones. We formally describe herein C. leucostigmata sp. nov., C. microdon sp. nov., and C. barazeri sp. nov. on the basis of specimens collected on Macclesfield Bank in the South China Sea, on the Chesterfield and Island of Pines plateau of New Caledonia, and off the New Ireland Province of Papua New Guinea, respectively. These new species are morphologically distinct from all other known species of Chelidoperca by body color pattern and combinations of a few identified characters. We also redescribe one of the lesser known species, C. lecromi, from fresh specimens collected close to its type locality and a new site in the Coral Sea. The distributional records for this and other known species are updated accordingly. Genetic references of the species as well as an updated identification key to western Pacific species are also provided.

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

Macroevolutionary Analyses Suggest That Environmental Factors, Not Venom Apparatus, Play Key Role in Terebridae Marine Snail Diversification, in Serb J.(Ed.), Systematic Biology 69(3): 413-430. 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.

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.

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.

Summers N. & Watling L. 2021. Upper Bathyal Pacific Ocean biogeographic provinces from octocoral distributions. Progress in Oceanography 191: 102509. DOI:10.1016/j.pocean.2020.102509
Abstract [+] [-]Biogeographical classification schemes such as the Marine Ecoregions of the World (MEOW) have been devel oped for continental shelf depths. The lack of faunal data in the deep sea has led to the development of biogeographical units based on oceanographic characteristics. The aim of this study was to propose biogeo graphical schemes for the Upper Bathyal (200–1000 m) across the Pacific Ocean using octocoral distributions. We retrieved over 200 000 octocoral data records from the Deep Sea Coral Data Portal (DSCDP), Ocean Biogeographic Information System (OBIS), Tropical Deep-Sea Benthos program (French National Museum of Natural History), Queensland Museum from the CIDARIS expeditions, and records retrieved from the Siboga expedition reports. We used cluster analysis to examine octocoral distributions against four different biogeo graphical classification schemes. The classification schemes produced mostly concordant patterns with three major faunal distribution barriers: the North Pacific Current isolates the subarctic units by creating a steep temperature gradient; the Subantarctic Front separates the Subantarctic from the rest of the Pacific; and the East Pacific Barrier separates the East Pacific from the Central and West Pacific. Two other smaller but distinct provinces are the Indo-Pacific where Lower Bathyal genera are found in the Upper Bathyal, and Torres Strait/ Coral Sea characterised by mesophotic genera. We propose 12 biogeographic provinces across the Pacific Ocean Upper Bathyal region from 200 to 1000 m depth based on octocoral distributions. The main driver for these units seems to be temperature, a defining feature of water masses. These units could potentially be subdivided into smaller regions based on habitat. Additionally, the clustering of Ecological Marine Units (EMUs) provides evi dence that the Upper Bathyal should in certain regions be divided vertically into two depth zones based on water masses.

Abstract [+] [-]Left-eyed flounders of the genus Chascanopsetta Alcock 1894 (Bothidae) occur in the Indian, Pacific, and Atlantic oceans at depths ranging from 120 to 1500 meters. They possess some unique features in bothid fishes including a strongly compressed and elongated body and a tremendously large mouth. Currently, nine species of Chascanopsetta are recognized, and three of them (C. micrognatha Amaoka & Yamamoto 1984, C. lugubris Alcock 1894 and C. prognatha Norman 1939) are distributed in the West Pacific. We collected 25 specimens of Chascanopsetta during 11 biodiversity expeditions carried out mainly in the West Pacific. Among them, eight specimens taken off Papua New Guinea present morphological features that differ from those of the three nominal species known in the West Pacific. In this study, we examined these eight specimens of unknown affinity and compared their morphology to that of specimens of other congeneric species. Results of these comparisons showed that these specimens represent an undescribed species of Chascanopsetta, named herein, C. novaeguineae sp. nov.. The new species resembles C. elski Foroshchuk 1991, which is known only from the Saya de Malha Bank in the western Indian Ocean, in having a high number of gill rakers (> 13). However, the combination of the following characters further distinguishes C. novaeguineae sp. nov. from C. elski: longer jaws, narrower interorbital width, and number of pseudobranches (21–25 vs. 26–27). The DNA sequences from the mitochondrial cytochrome oxidase subunit I (COI) gene from C. novaeguineae sp. nov. and other species were obtained and compared to confirm its taxonomic status and to infer its tentative phylogenetic position within the Chascanopsetta.

Abstract [+] [-]In this study we list and figure a total of 22 species assigned to the genus Ilanga Herbert, 1987 that were collected during recent Paris Museum expeditions, of which 16 are new and described here (listed in the order they appear in the text): Ilanga herberti n. sp., I. euryomphalos n. sp., I. polygramma n. sp., I. stephanophora n. sp., I. harrytaylori n. sp., I. eurystoma n. sp., I. oxeia n. sp., I. cosmia n. sp., I. corrineae n. sp., I. comes n. sp., I. dongshaensis n. sp., I. philia n. sp., I. helicoides n. sp., I. lauensis n. sp., I. mesembrine n. sp. and I. boreia n. sp.. These species occur throughout the Indo-West Pacific, extending the known range of this genus beyond the south west Indian Ocean. We also synonymise Microgaza fulgens Dall, 1907 and Microgaza konos Vilvens, 2009 (syn. nov.) (as I. fulgens). New combinations include Ilanga fulgens and I. navakaensis.

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.
