Abdelkrim J., Aznar-cormano L., Fedosov A.E., Kantor Y.I., Lozouet P., Phuong M.A., Zaharias P. & Puillandre N. 2018. Exon-Capture-Based Phylogeny and Diversification of the Venomous Gastropods (Neogastropoda, Conoidea), in Vidal N.(Ed.), Molecular Biology and Evolution 35(10): 2355-2374. DOI:10.1093/molbev/msy144
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.

Anker A. 2014. Naushonia draconis sp. nov., a heavily armoured mud shrimp from the Caribbean Sea, and taxonomic status of Espeleonaushonia Juarrero & Martínez-Iglesias, 1997 (Decapoda: Gebiidea: Laomediidae). Marine Biology Research 10(8): 755-770. DOI:10.1080/17451000.2013.852684
Abstract [+] [-]The diagnostic characters of the laomediid mud shrimp genus Espeleonaushonia Juarrero & Martínez-Iglesias, 1997 are reassessed and the genus is synonymized with Naushonia Kingsley, 1897. A new species of Naushonia is described based on a single male collected at a depth of 16 m off the coast of Guadeloupe, French Antilles. Naushonia draconis sp. nov. is closest to two species of Naushonia formerly placed in Espeleonaushonia, namely Naushonia palauensis (Alvarez, Villalobos & Iliffe, 2010) comb. nov. and Naushonia augudrea (Juarrero & García, 1997) comb. nov., but can be separated from both of them and all other species of Naushonia by the high mid-dorsal carina, a row of very strong spines on the lateral surface of the carapace, and prominent mid-dorsal crests on the first, second and third pleomeres. A key to all known species of Naushonia is provided.

Anker A. 2017. Strongly carinate species of Alpheopsis Coutière, 1897 of the tropical Atlantic and eastern Pacific, with redescription of A. trigona (Rathbun, 1901) and description of three new species (Malacostraca: Decapoda: Alpheidae). Zootaxa 4277(2): 199-227. DOI:10.11646/zootaxa.4277.2.2
Abstract [+] [-]The present study deals with four species of the alpheid shrimp genus Alpheopsis Coutière, 1897 characterised by the presence of at least one strong carina on the dorsal surface of the carapace. Alpheopsis trigona (Rathbun, 1901) is redescribed based on the holotype from Puerto Rico and additional material from US Virgin Islands and Florida. Two new species closely related to A. trigona, viz. A. paratrigona sp. nov. and A. gotrina sp. nov., are described, the first based on material from several localities in the tropical western Atlantic, and the second from the Pacific coast of Panama and Colombia. The three species together form a distinctive transisthmian clade within Alpheopsis, the A. trigona species complex, characterised by the presence of several strong longitudinal carinae on the carapace and very distinctive colour pattern. A more distantly related species, A. aristoteles sp. nov., characterised by the presence of only one strong mid-dorsal carina in the anterior region of the carapace, is described based on material from São Tomé Island in the tropical eastern Atlantic.

Baeza J.A. & Ocampo E.H. 2018. THE LIFE CYCLE OF SYMBIOTIC CRUSTACEANS: A PRIMER. : 28
Abstract [+] [-]In the subphylum Crustacea, species from most major clades have independently evolved symbiotic relationships with a wide variety of invertebrate and vertebrate hosts. Herein, we review the life cycle disparity in symbiotic crustaceans. Relatively simple life cycles with direct or abbreviated development can be found among symbiotic decapods, mysids, and amphipods. Compared to their closest free-living relatives, no major life cycle modi cations were detected in these clades as well as in most symbiotic cirripeds. In contrast, symbiotic isopods, copepods, and tantulocarids exhibit complex life cycles with major di erences compared to their closest free-living relatives. Key modi cations in these clades include the presence of larval stages well endowed for dispersal and host infestation, and the use of up to di erent host species with dissimilar ecologies throughout their ontogeny. Phylogenetic inertia and restrictions imposed by the body plan of some clades appear to be most relevant in determining life cycle modi cations (or the lack thereof) from the “typical” ground pa ern. Furthermore, the life cycle ground pa ern is likely either constraining or favoring the adoption of a symbiotic lifestyle in some crustacean clades (e.g., in the ecostraca).

Caballer M. & Ortea J. 2014. A new sibling species of Notobryon (Gastropoda, Nudibranchia) from the Caribbean Sea. Journal of the Marine Biological Association of the United Kingdom 94(7): 1-6. DOI:10.1017/S0025315414000605
Abstract [+] [-]A new Scyllaeidae of the genus Notobryon is described from Guadeloupe, in the Lesser Antilles. Notobryon caribbaeus sp. nov. is characterized by having the anterior pair of body lobes remarkably bigger than the posterior pair, a stomach with eight triangular plates, a black and very wide ampulla, a lemon-shaped bursa copulatrix and a complex and welldifferentiated sponge-like prostate. The first Caribbean records of Notobryon were provisionally assigned to the Australian species Notobryon cf. wardi and later transferred to Notobryon panamica. However, the structure of the male genital system is one of the main morphological characters to discriminate species in the genus and the presence of a prostate in N. caribbaeus sp. nov. distinguishes it from N. panamica, which remains confined to the eastern Pacific. Of the remaining four species in the world, only Notobryon bijecurum shares this character, but its external anatomy is different: it lacks a bursa copulatrix and the deferent duct is much shorter. Notobryon caribbaeus sp. nov. was captured in the context of an intensive expedition (‘Karubenthos’) organized by the Muse´um National d’Histoire Naturelle, Paris and its description raises the total inventory of sea slugs in Guadeloupe to 150.

Caballer M. & Ortea J. 2015. A New Shallow Water Species of the Genus Philine ascanius, 1772 (Mollusca: Opisthobranchia: Philinidae) from Venezuela. Journal de Conchyliologie 42(1): 33-40
Abstract [+] [-]A new shallow water species of the genus Philine Ascanius, 1772 is described from the coastal lagoons of the Bay of Buche, Venezuela. This species is characterized by the color pattern of its body, yellowish with white dots, the cephalic shield, as long as the posterior shield, the internal shell with the rear posterior edge not surpassing the apex and the sculpture composed of 6 to 18 striking spiral lines, the innermost lateral teeth of the radula, bearing 10–19 denticles in the masticatory margin and by lacking gizzard plates. Philine buchensis new species is compared with all the species of the genus known to date in the Caribbean, particularly withthose from coastal areas (0–10m): Philine sagra (d´Orbigny, 1841) and Philine caballeri Ortea, Espinosa & Moro, 2001.

Abstract [+] [-]The nudibranch gastropod genus Aeolidiella Bergh, 1867 has been found to be polyphyletic. It holds an unnamed clade that was named Bulbaeolidia Carmona, Pola, Gosliner & Cervera, 2013. This genus is composed by four species, two of them unnamed: Bulbaeolidia alba, from Japan,Malaysia and Philippines, Bulbaeolidia japonica, from Japan, Bulbaeolidia sp. B, from Hawaii, and Bulbaeolidia sp. A, from Brazil. Bulbaeolidia was described in the context of a molecular phylogeny, thus, no “taxonomic action” regarding to the unnamed species was taken, leaving the work incomplete, and the 50 % of the members of Bulbaeolidia undescribed. In this paper we describe the Western Atlantic member of the genus Bulbaeolidia and a Pacific species from Galapagos, both cryptic with Bulbaeolidia alba (Risbec, 1929).

Abstract [+] [-]The Indo-Pacific genus Spiniphiline Gosliner, 1988 was erected for a rare species of Cephalaspidea characterized by an internal shell with spines. Spiniphiline kensleyi Gosliner, 1988 was until now the only known species. During the ‘Karubenthos’ expedition to the archipelago of Guadeloupe (Lesser Antilles, Caribbean Sea) coordinated by the Muse´um national d’Histoire naturelle, Paris, a small philinid was captured on a ma¨ erl bed. This specimen is here described as a new species of Spiniphiline—S. persei. Its occurrence in Guadeloupe is the first record of the genus in the Atlantic Ocean. The systematic position of Spiniphiline is discussed and evidence given for its inclusion in the family Philinidae s. s.

Chen C.L., Goy J.W., Bracken-grissom H.D., Felder D.L., Tsang L.M. & Chan T.Y. 2016. Phylogeny of Stenopodidea (Crustacea : Decapoda) shrimps inferred from nuclear and mitochondrial genes reveals non-monophyly of the families Spongicolidae and Stenopididae and most of their composite genera. Invertebrate Systematics 30(5): 479-490. DOI:10.1071/IS16024
Abstract [+] [-]The infraorder Stenopodidea is a relatively small group of marine decapod crustaceans including the well known cleaner shrimps, but their higher taxonomy has been rather controversial. This study provides the most comprehensive molecular phylogenetic analyses of Stenopodidea using sequence data from two mitochondrial (16S and 12S rRNA) and two nuclear (histone H3 and sodium–potassium ATPase a-subunit (NaK)) genes. We included all 12 nominal genera from the three stenopodidean families in order to test the proposed evolutionary hypothesis and taxonomic scheme of the group. The inferred phylogeny did not support the familial ranking of Macromaxillocarididae and rejected the reciprocal monophyly of Spongicolidae and Stenopididae. The genera Stenopus, Richardina, Spongiocaris, Odontozona, Spongicola and Spongicoloides are showed to be poly- or paraphyletic, with monophyly of only the latter three genera strongly rejected in the analysis. The present results only strongly support the monophyly of Microprosthema and suggest that Paraspongiola should be synonymised with Spongicola. The three remaining genera, Engystenopus, Juxtastenopus and Globospongicola, may need to be expanded to include species from other genera if their statuses are maintained. All findings suggest that the morphological characters currently adopted to define genera are mostly invalid and substantial taxonomic revisions are required. As the intergeneric relationships were largely unresolved in the present attempt, the hypothesis of evolution of deep-sea sponge-associated taxa from shallow-water free-living species could not be verified here. The present molecular phylogeny, nevertheless, provides some support that stenopoididean shrimps colonised the deep sea in multiple circumstances.

Couto D.R., Bouchet P., Kantor Y.I., Simone L.R.L. & Giribet G. 2016. A multilocus molecular phylogeny of Fasciolariidae (Neogastropoda: Buccinoidea). Molecular Phylogenetics and Evolution 99: 309-322. DOI:10.1016/j.ympev.2016.03.025
Abstract [+] [-]The neogastropod family Fasciolariidae Gray, 1853 – tulips, horse-conchs, spindles, etc., comprises important representatives of tropical and subtropical molluscan assemblages, with over 500 species in the subfamilies Fasciolariinae Gray, 1853, Fusininae Wrigley, 1927 and Peristerniinae Tryon, 1880. Fasciolariids have had a rather complicated taxonomical history, with several genus names for a long time used as waste baskets to group many unrelated species; based on shell characters, recent taxonomic revisions have, however, began to set some order in its taxonomy. The present work is the first molecular approach to the phylogeny of Fasciolariidae based on a multigene dataset, which provides support for fasciolariids, an old group with a fossil record dating back to the Cretaceous. Molecular markers used were the mitochondrial genes 16S rRNA and cytochrome c oxidase subunit I, and the nuclear genes 18S rRNA, 28S rRNA and histone H3, sequenced for up to 116 ingroup taxa and 17 outgroups. Phylogenetic analyses revealed monophyly of Dolicholatirus Bellardi, 1884 and Teralatirus Coomans, 1965, however it was not possible to discern if the group is the sister clade to the remaining fasciolariids; the latter, on the other hand, proved monophyletic and contained highly supported groups. A first split grouped fusinines and Pseudolatirus Bellardi, 1884; a second split grouped the peristerniine genera Peristernia Mörch, 1852 and Fusolatirus Kuroda and Habe, 1971, while the last group comprised fasciolariines and the remaining peristerniines. None of these clades correspond to the present-day accepted circumscription of the three recognized subfamilies.

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. As the sister group to all other fissurellids, Rimula is ranked in its own subfamily, Rimulinae stat. nov. New synonyms: Hemitominae syn. nov. of Zeidorinae stat. nov.; Cranopsis syn. nov. of Puncturella; Variegemarginula syn. nov. of Montfortula.

Abstract [+] [-]Five new species of Homoscleromorpha (Porifera) of four genera, Oscarella, Plakortis, Plakina and Corticium, are described from vertical walls of reef caves at depths ranging from 23 to 28 m in the Caribbean Sea. Oscarella nathaliae sp. nov. has a leaf-like thinly encrusting, flat body, loosely attached to the substrate and a perforated, not lobate surface. Oscarella nathaliae sp. nov. contains two bacterial morphotypes and is characterized by two mesohylar cell types with inclusions. Plakortis myrae sp. nov. has diods of two categories: abundant large ones (83–119 mm long) and rare small ones (67–71 mm long) with sinuous, S-bent centres; triods Y- or T-shaped (18–5 mm long), and abundant microrhabds (5–12 mm long). Plakortis edwardsi sp. nov. has diods of one category with thick, sinuous, S-bent centres (110 to 128 mm long); triods T-shaped (actines 28–59 mm long). It is the only species of this genus showing small diods (22–31 mm long). Plakortis dariae sp. nov. has diods of two categories: large ones (67–112 mm long) and small, rare, irregular ones, slightly curved, often deformed with one end blunt (30–59 mm long); triods rare and regular (actines 20–44 mm long). Corticium diamantense sp. nov. has oscula situated near its border, regular non-lophose calthrops of one size-class, very rare tetralophose calthrops and candelabra with the fourth actine ramified basally in 4–5 microspined rays. In addition, a re-description of Plakina jamaicensis is based on newly collected material and the type specimen. Plakortis jamaicensis has a convoluted brain-like surface; well developed sub-ectosomal cavities; irregular sinuous diods, triods, calthrops, rare monolophose calthrops, rare dilophose calthrops, rare trilophose calthrops and common tetralophose calthrops. Molecular ‘barcoding’ sequences for mitochondrial cob are given for Plakortis edwardsi sp. nov., P. dariae sp. nov., Plakina jamaicensis and Corticium diamantense sp. nov. An identification key for all western Atlantic Homoscleromorpha is provided.

In addition, characteristics that distinguish each genus currently in use for TWA shallow water species have indicated the need for reassignment (new combinations within Drilliidae) of 15 species. Some nomenclatural actions have come about from the literature review and include one taxon placed in junior synonymy (under an older name recently re-discovered) and one new name for a junior homonym. Two neotypes, five lectotype designations, and one new name are also proposed. Altogether, nomenclatural actions on 17% of valid previously described taxa are proposed. The 100 proposed names are placed in 12 available and one new genus: Agladrillia Woodring, 1928 (2), Bellaspira Conrad, 1868 (7), Calliclava McLean, 1971 (3), Cerodrillia Bartsch & Rehder, 1939 (11), Clathrodrillia Dall, 1918 (6), Decoradrillia, new genus (4), Douglassia Bartsch, 1934 (4), Fenimorea Bartsch, 1934 (15), Leptadrillia Woodring, 1928 (12), Lissodrillia Bartsch & Rehder, 1939 (8), Neodrillia Bartsch, 1943 (2), Splendrillia Hedley, 1922 (13), and Syntomodrillia Woodring, 1928 (13). These are the first reports of Calliclava in the western Atlantic, previously known only from the eastern Pacific. The new genus, Decoradrillia, is proposed to hold four new species and one existing that share a unique shell microsculpture and other morphological traits. One genus, Drillia Gray, 1838, is not currently believed to have TWA representatives. Three genera comprised exclusively of bathyal species are not treated in this work: Clavus Monfort, 1810 (=Eldridgea Bartsch, 1934), Globidrillia Woodring, 1928, and SpirotropisSars, 1878. The significant increase in species within all of the genera has the effect of strengthening the groups’ diagnostic characters by their presence across a greater number of species. Each of the 148 valid species treated herein are described (or redescribed) and photographs of types presented, as are photographs of morphological variants and representatives from separate geographic areas, if available, to illustrate species’ variability.

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.

The collapse of Mitra: molecular systematics and morphology of the Mitridae (Gastropoda: Neogastropoda). Zoological Journal of the Linnean Society 20: 1-85. DOI:10.1093/zoolinnean/zlx073/4855867
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 [+] [-]Charybdis hellerii (A. Milne Edwards, 1867), a crab native to the Indo-West Pacific, was introduced in the western Atlantic in the late 1980s, likely through transport of larvae in ballast water of ships. It has since been reported from North Carolina, southeastern coast of United States, to southern Brazil. This report from Martinique is the first from the Lesser Antilles. Specimens were collected during scuba-diving surveys conducted during March/April 2016 to study the population size, distribution, and habitat-use of this invader. Two hundred and thirteen transects, each 60 m2, were searched, in 2–15 m depths, in five coves of the southwestern peninsula of the island. We observed 150 individuals, of which 135 were collected. Most (89 %) specimens were mature with a male:female sex ratio of 2.4:1. Carapace widths ranged between 17.3 and 58.1 mm, with males significantly larger than females. Most crabs (93%) were found in dense seagrass beds of Halophila stipulacea, although a few (7%) were found on bare substrate with rocks and artificial mooring blocks. C. hellerii was absent from sand, coral with rocks and sponges, and mixed beds of algae and seagrass, possibly due to the presence of predators. The maximum observed density in the dense seagrass beds was 0.37 crab m-2. Predatory behavior of C. hellerii on other crabs was observed, suggesting this alien crab could alter existing community structure and functioning.

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 [+] [-]Nine new species of Muricidae from Guadeloupe, mainly collected during the 2012 KARUBENTHOS expedition, are described. Typhinellus lamyi n. sp. is compared with the similar species T. labiatus (Cristofori & Jan, 1832) from the Mediterranean Sea and T. occlusus (Garrard, 1963) from the Philippines. Dermomurex (Trialatella) pruvosti n. sp., D. (T.) boucheti n. sp., D. (T.) fajouensis n. sp. and D. (T.) tararensis n. sp. are compared with D. abyssicola (Crosse, 1865) occurring in the same area and with D. (T.) oxum Petuch, 1979 which ranges from Panama to Brazil. Pygmaepterys pointieri n. sp. and P. karukerensis n. sp. are compared with P. germainae Vokes & D’Attilio, 1980 and P. aliceae (Petuch, 1987). Muricopsis guadalupensis n. sp. is compared with M. caribbaea (Bartsch & Rehder, 1939) occurring throughout the Tropical West Atlantic and to M. marcusi Vokes, 1994 from Brazil. Lindapterys domlamyi n. sp. is compared with L. sanderi Petuch, 1987 from Barbados and Brazil and to the type species of the genus, L. vokesae Petuch, 1987 from the Early Miocene of Florida (USA). The name Murex hexagonus Lamarck, 1816, usually considered to be a primary homonym of Murex hexagonus (Gmelin, 1791), is rehabilitated (article 23.9.5, ICZN 1999). A lectotype of this species, is designated from the two syntypes housed in the MNHNG. Murex hexagonus is compared with other related Murexsul from the Caribbean area including M. oxytatus (Smith, 1938), M. zylmanae (Petuch, 1993), M. huberti (Radwin & D’Attilio, 1976), M. chesleri Houart, 2006, M. sunderlandi (Petuch, 1987), M. warreni (Petuch, 1993) and M. jahami Merle & Garrigues, 2011.

Abstract [+] [-]Trois nouvelles espèces de Muricidae ont été collectées au cours de l’expédition « La Planète Revisitée » en Guyane Française en 2014-2015. Les deux premières, Phyllonotus guyanensis n. sp. et Phyllonotus salutensis n. sp. appartiennent au genre Phyllonotus Swainson, 1833. Dans la région Atlantique Ouest, cinq espèces sont actuellement répertoriées dans ce genre : Phyllonotus pomum (Gmelin, 1791), P. oculatus (Reeve, 1845), P. margaritensis (Abbott, 1958), P. globosus Emmons, 1858 et P. whymani Petuch & Sargent, 2011. Phyllonotus guyanensis n. sp. décrit ici est comparé à deux espèces proches : P. pomum et P. whymani. Phyllonotus pomum est largement répandu de la Caroline du Nord au Nord de l’Amérique du Sud tandis que P. whymani n’est connu que de sa localité-type, Dry Tortuga, Florida Keys. La deuxième espèce, Phyllonotus salutensis n. sp., est comparée à P. margaritensis des Iles du nord-est du Venezuela, P. globosus de la presqu’île du Paraguana au nord-ouest du Venezuela et P. pomum. Murex mexicanus Petit de la Saussaye, 1852, du Golfe du Mexique, (non Murex mexicanus Stearns, 1894 = Chicoreus maurus (Broderip, 1833)) a toujours été confondu avec P. pomum. Il est ici réhabilité sous le taxon de Phyllonotus mexicanus (Petit de la Saussaye, 1852). Phyllonotus oculatus se distingue de toutes les autres espèces nommées ci-dessus par une protoconque multispirale (Houart, 1987) et n’est pas abordé ici. La troisième espèce est une Favartia Jousseaume, 1880, Favartia charlesi n. sp. Elle est comparée avec l’espèce voisine F. hidalgoi (Crosse, 1869) rencontrée du Golfe du Mexique au Sud du Brésil entre 120 et 400 m de profondeur.

Abstract [+] [-]A new shallow water species of the lucinid bivalve Pleurolucina is described from Curaçao in the southern Caribbean Sea and compared with known species of the genus from the western Atlantic and eastern Pacific Oceans. Although confused with the Floridian species P. leucocyma, it is most similar to the eastern Pacific P. undata. As in all studied lucinids, the new species possesses symbiotic bacteria housed in the ctenidia. The shell microstructure is unusual with repeated and intercalated conchiolin layers that have sublayers of ‘tulip-shaped’ calcareous spherules. Predatory drillings by naticid gastropods frequently terminate at the conchiolin layers.

Abstract [+] [-]All Jurassic brachyuran taxa known to date are based solely upon dorsal carapaces, and only a limited number of Early and mid-Cretaceous crabs retain ventral parts. Therefore, all Jurassic taxa and many forms from the first half of the Cretaceous are carapace-based entities. All of them are considered to be “dromiaceans”, podotremes to be precise. The recent discovery of an exceptionally well-preserved male crab from the Upper Cretaceous (lower Cenomanian) of Chiapas (Mexico), Archaeochiapasa mardoqueoi Guinot, Carbot-Chanona & Vega, 2019, at first sight of a podotreme nature, has allowed a detailed description of its thoracic sternum and pleon, which revealed that it was actually a typical eubrachyuran, in need of a new family, Archaeochiapasidae Guinot, Carbot-Chanona & Vega, 2019. This has brought back to life one of my earlier ideas about the possible non-podotreme nature of certain enigmatic Late Jurassic and Cretaceous Brachyura previously placed in various “dromiacean” (i.e., podotreme) families and superfamilies. My investigations have led the me to formulate the present hypothesis that the extinct families Bucculentidae Schweitzer & Feldmann, 2009 (currently assigned to the Homolodromioidea Alcock, 1900), Lecythocaridae Schweitzer & Feldmann, 2009, Glaessneropsidae Schweitzer & Feldmann, 2009, Nodoprosopidae Schweitzer & Feldmann, 2009, and Viaiidae Artal, Van Bakel, Fraaije, Jagt & Klompmaker, 2012 (all four in Glaessneropsoidea Schweitzer & Feldmann, 2009) might, in fact (at least for some of them), be true eubrachyurans (Eubrachyura Saint Laurent, 1980). If correct, these assumptions would date the first “true crabs” as Jurassic, contrary to the currently held view that the earliest Eubrachyura (heterotremes) did not appear until the Cretaceous, and suggest that the evolutionary history of brachyurans started much earlier. This was unpredictable, at least for palaeontologists, but not so in view of a molecular estimate of decapod phylogeny that recovered the Majoidea Samouelle, 1819 as the oldest brachyuran lineage, with a divergence from other brachyurans from, at least, the Middle Triassic. The basal majoid family Oregoniidae Garth, 1958, which comprises only three extant genera, has several characters in common with Archaeochiapasidae; these leave little doubt about their close relationships.

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 [+] [-]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.

Abstract [+] [-]Six new monotypic genera and eight new species of hermit crabs of the family Paguridae Latreille, 1802 are fully described based on specimens obtained during two separate, intensive biodiversity studies on the islands of Guadeloupe, Curaçao, and Dominica in the Lesser Antilles, Caribbean Sea. The study in Guadeloupe utilized a broad variety of sampling techniques, including dredging, baited traps, and a SCUBA-operated vacuum device; in Curaçao and Dominica, a manned submersible was used. The high number of new taxa discovered is surprising given they were obtained in a relatively small area of the Antilles in habitats ranging in depth from shallow water (c. 1 m) to deep reefs (250 m). Tissue samples were extracted from most specimens for CO1 barcoding and other genetic analyses for future phylogenetic investigations. Gene sequences are reported to complement the morphological descriptions. The new species are unusual in their minute sizes, ranging 0.4-1.5 mm in shield length; and aspects of their morphology, in particular gill number and characteristics of male sexual tubes, which could not be clearly matched to any of the existing genera of Paguridae. The term “micro-pagurid” is introduced for this diverse, diminutive fauna of Paguridae (adult shield length ≤ 1.5 mm), discovered living in cryptic habitats and complex deep reef structures of these three islands. A brief, preliminary discussion of the possible significance of this micro-pagurid diversity, specialized morphology, and biogeography is included.

Abstract [+] [-]The family Pinnidae Leach, 1819, includes approximately 50 species of large subtidal and coastal marine bivalves. These commercially important species occur in tropical and temperate waters around the world and are most frequently found in seagrass meadows. The taxonomy of the family has been revised a number of times since the early 20th Century, the most recent revision recognizing 55 species distributed in three genera: Pinna, Atrina and Streptopinna, the latter being monotypic. However, to date no phylogenetic analysis of the family has been conducted using morphological or molecular data. The present study analyzed 306 pinnid specimens from around the world, comprising the three described genera and ca. 25 morphospecies. We sequenced the mitochondrial genes 16S rRNA and cytochrome c oxidase subunit I, and the nuclear ribosomal genes 18S rRNA and 28S rRNA. Phylogenetic analysis of the data revealed monophyly of the genus Atrina but also that the genus Streptopinna is nested within Pinna. Based on the strong support for this relationship we propose a new status for Streptopinna Martens, 1880 and treat it as a subgenus (status nov.) of Pinna Linnaeus, 1758. The phylogeny and the species delimitation analyses suggest the presence of cryptic species in many morphospecies displaying a wide Indo-Pacific distribution, including Pinna muricata, Atrina assimilis, A. exusta and P. (Streptopinna) saccata but also in the Atlantic species A. rigida. Altogether our results highlight the challenges associated with morphological identifications in Pinnidae due to the presence of both phenotypic plasticity and morphological stasis and reveal that many pinnid species are not as widely distributed as previously thought.

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 [+] [-]All the species of the genres Pleurobranchus Cuvier, 1804 and Berthellina Gardiner, 1936 described or cited in the Macaronesia are revised. The records of Pleurobranchus areolatus Mörch, 1863 in the Canaries are transferred to Pleurobranchus crossei Vayssiere, 1896. Pleurobranchus lowei Watson, 1897, from Madeira, is synonymized with Berthellina edwardsi (Vayssiere, 1896). The name Pleurobranchus garciagomezi Cervera, Cattaneo & Edmunds, 1996 is applied to the specimens, endemic to Cape Verde, that match in the chromatic pattern of the holotype of this species. Pleurobranchus wirtzi, new species, is described to include the rest of the specimens from other islands in the Macaronesia, identified in the literature as P. garciagomezi. Two new species of Berthella Blainville, 1828 and Berthellina are described from Cape Verde and compared with two Caribbean taxa, Pleurobranchus evelinae Thompson, 1978 and Berthellina quadridens (Mörch, 1863). New anatomical data are given on the latter. In addition, the Pleurobranchidae from Galapagos obtained in the expeditions organized by the “Museo de Ciencias Naturales de Tenerife” in Tenerife is studied, given that two Atlantic species, Pleurobranchus areolatus and Berthellina engeli Gardiner, 1936, have been recorded there.

Abstract [+] [-]In the most recent molecular phylogeny of the Aglajidae, the Caribbean species Aglaja felis Marcus & Marcus, 1970 was transferred to the Japanese genus Nakamigawaia Kuroda & Habe in Habe, 1961 without justification or support. The assumed N. felis was used as the only representative of the genus in the phylogeny, which did not include the type species: Nakamigawaia spiralis Kuroda & Habe in Habe, 1961. The material determined as A. felis came from Bahamas, Papua New Guinea and Philippines and the conclusion was that they were a complex of species; the Indo-Pacific ones possibly new and all of them belonging to the genus Nakamigawaia. Nonetheless, a simple comparison of shells of the type species of Aglaja Renier, 1881 and Nakamigawaia with A. felis, shows remarkable and supra-specific differences. Thus, in absence of N. spiralis, Nakamigawaia would not be represented in the phylogeny of the Aglajidae, but a distinct taxa, distributed in the Caribbean and the Indo-Pacific. Migaya Ortea, Caballer & Espinosa new genus, is proposed to relocate A. felis. This genus is characterized by bearing sensorial bristles on the head, by its internal shell and supported by the molecular phylogeny. In the same phylogeny, the genus Chelidonura A. Adams, 1850 was fragmented in several independent clades, one of them, characterized by the shell bearing a crest in the protoconch. Two new species of this clade are described in this paper. The shell can be very helpful to assign the right names in the Aglajidae and using it is recommended even in papers where the molecular techniques are applied. A visual analysis of the usefulness of the shell within the group is performed using the established phylogeny as a frame for comparison.

Abstract [+] [-]The present study is the first major assessment of the marine decapod fauna of Ceará, northeastern Brazil, since contributions of J. Fausto-Filho in the 1960s–1970s. A fully updated checklist of all decapod crustaceans occurring in marine and estuarine habitats of Ceará is provided, based on literature records, specimens held in two carcinological collections of the Universidade Federal do Ceará (UFC), and material collected mainly by the authors between 2011 and 2014. A total of 337 decapod species are listed, distributed among the following taxa: Achelata (8 species), Anomura (42 species), Astacidea (1 species), Axiidea (11 species), Brachyura (162 species), Caridea (83 species), Dendrobranchiata (20 species), Gebiidea (9 species), and Stenopodidea (1 species). Among them, 23 species represent new records for Ceará, with 14 species, viz. Alpheus peasei (Armstrong, 1940), A. thomasi Hendrix & Gore, 1973, Ambidexter symmetricus Manning & Chace, 1971, Axianassa australis Rodrigues & Shimizu, 1992, Biffarius biformis (Biffar, 1971), B. fragilis (Biffar, 1970), Leptalpheus axianassae Dworschak & Coelho, 1999, L. forceps Williams, 1965, Lysmata bahia Rhyne & Lin, 2006, L. intermedia (Kingsley, 1878), Merhippolyte americana Holthuis, 1961, Neocallichirus maryae Karasawa, 2004, Ogyrides hayi Williams, 1981, and Typton carneus Holthuis, 1951, now having Ceará as the northern-most limit in their distribution range along the Brazilian coastline. One shrimp species, Lysmata lipkei Okuno & Fiedler, 2010, which was also found in the state of Rio Grande do Norte, possibly represents an invasive taxon in Brazil and the western Atlantic, originating from the Indo-West Pacific. Alpheus buckupi Almeida, Terossi, Araújo-Silva & Mantelatto, 2013, previously recorded from Ceará based on a colour photograph, is confirmed from this state, with specimens from several new localities. A few doubtful records from Ceará are briefly discussed. Colour photographs are provided for most of the taxa newly recorded from Ceará; some species are illustrated in colour for the first time.

Abstract [+] [-]The present study documents species of coralline algae that form maerl and rhodoliths in Guadeloupe, Caribbean using an integrative systematic approach of combining molecular (COI-5P, psbA) and morphological/anatomical data. Maerl and rhodoliths were collected by SCUBA and dredging from six localities in Guadeloupe during the Karubenthos Expedition, which was coordinated by the Parc National de la Guadeloupe and the Muséum National d´Histoire Naturelle. Of the twelve maerl and rhodolith specimens collected and sequenced, eight specific entities were delimitated based on the analysis of molecular data: Lithothamnion cf. ruptile, five species of the genus Lithothamnion, one species of the genus Spongites, and the remaining one was either assigned to the genus Lithoporella or Mastophora. Morphological/anatomical data are presented for each of these species. Molecular analyses revealed that Lithothamnion. cf ruptile and other four species (Lithothamnion spp.1–4) were resolved in a distinct lineage than the other Lithothamnion species examined. Nevertheless, these five species were provisionally remained in the genus Lithothamnion based on the presence of flared epithallial cells. Previously, only three species of Lithothamnion have been cited in the Caribbean. Till this study species belonging to the genus Spongites have not been hitherto reported for this region. The specimen identified as either Lithoporella or Mastophora shared anatomical features with both genera. Further examination of reproductive material is required to identify this specimen to a lower taxonomical rank. This study is the first to report the occurrence of maerl and rhodoliths belonging to the genus Lithothamnion at 110 m depth; this record being the deepest for the genus in the Caribbean Sea. Our results have revealed that species diversity of Caribbean maerl has been underestimated and further surveys coupled with an integrative taxonomic approach on this biodiversity hotspot are necessary.

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

Abstract [+] [-]A collection of porcellanid crabs from Guadeloupe Island, Caribbean Sea Lesser Antilles, is reported. The specimens were obtained during the KARUBENTHOS Expedition (V.2012), a 1-month intensive survey of selected habitats in shallowwater to moderate depth (intertidal to 160 m). A total of 20 species were found, 15 of which represent new records for Guadeloupe Island. Almost all species were photographed in color shortly after capture. For each species, a diagnosis, notes on habitat, geographical distribution, and taxonomic remarks, are given. The 20 species of porcellanid crabs found in Guadeloupe Island represent 54% of a total of 37 species known from the entire Lesser Antilles (Anguilla to Trinidad) and the islands off Venezuela (Testigos to Aruba). The richness of the porcellanid fauna of Guadeloupe Island indicates a high biodiversity potential in other decapod crustaceans or invertebrates in general, living in marine habitats of this Island.

Abstract [+] [-]A preliminary assessment of the deep-sea Decapoda is proposed for Guadeloupe Island based solely on high definition macro photographs taken during the KARUBENTHOS 2015 Expedition to the Island (R/V Antea, 7–29 June 2015). Overall, 190 species are recognized, several of which are depicted with their fresh color for the first time. Previous records in the Lesser Antilles are documented and the geographic distribution of the species in these Islands is given. The historical contribution of the steamer Blake (1878–1879) in the Lesser Antilles is emphasized. All species inventoried during KARUBENTHOS 2015 were already reported in the western Atlantic but 34 of them are new records for the Lesser Antilles and 116 are reported for the first time from Guadeloupe Island. This preliminary inventory is estimated to include about 38% of the deep-sea Decapoda potentially occurring around Guadeloupe Island.

Rousseau F., Gey D., Kurihara A., Maggs C.A., Martin-lescanne J., Payri C., De reviers B., Sherwood A.R. & Le gall L. 2017. Molecular phylogenies support taxonomic revision of three species of Laurencia (Rhodomelaceae, Rhodophyta), with the description of a new genus. European Journal of Taxonomy 269: 1-19. DOI:10.5852/ejt.2017.269
Abstract [+] [-]The systematics of the Laurencia complex was investigated using a taxon-rich data set including the chloroplast ribulose-1,5-bisphosphate carboxylase/oxygenase large subunit (rbcL) gene only and a character-rich data set combining mitochondrial cytochrome oxidase 1 (COI-5P), the rbcL marker, and the nuclear large subunit of the ribosomal operon (LSU). Bayesian and ML analyses of these data sets showed that three species hitherto placed in the genus Laurencia J.V.Lamour. were not closely related to Laurencia s. str. Laurencia caspica Zinova & Zaberzhinskaya was the sister group of the remaining Osmundea Stackh. species, L. crustiformans McDermid joined Palisada and L. fl exilis Setch. consisted of an independent lineage. In light of these results a new genus, Ohelopapa F.Rousseau, Martin-Lescanne, Payri & L.Le Gall gen. nov., is proposed to accommodate L. fl exilis. This new genus is morphologically characterized by four pericentral cells in each vegetative axial segment; however, it lacks ‘corps en cerise’ in cortical cells and secondary pit connections between cortical cells, which are characteristic of Laurencia. Three novel combinations are proposed to render the classifi cation closer to a natural system: Ohelopapa fl exilis (Setch.) F.Rousseau, Martin-Lescanne, Payri & L.Le Gall comb. nov., Osmundea caspica (Zinova & Zaberzhinskaya) Maggs & L.M.McIvor comb. nov. and Palisada crustiformans (McDermid) A.R.Sherwood, A.Kurihara & K.W.Nam comb. nov.

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 [+] [-]A new, more complete, five-marker (SSU, LSU, psbA, COI, 23S) molecular phylogeny of the family Corallinaceae, order Corallinales, shows a paraphyletic grouping of seven well-supported monophyletic clades. The taxonomic implications included the amendment of two subfamilies, Neogoniolithoideae and Metagoniolithoideae, and the rejection of Porolithoideae as an independent subfamily. Metagoniolithoideae contained Harveylithon gen. nov., with H. rupestre comb. nov. as the generitype, and H. canariense stat. nov., H. munitum comb. nov., and H. samo€ense comb. nov. Spongites and Pneophyllum belonged to separate clades. The subfamily Neogoniolithoideae included the generitype of Spongites, S. fruticulosus, for which an epitype was designated. Pneophyllum requires reassesment. The generitype of Hydrolithon, H. reinboldii, was a younger heterotypic synonym of H. boergesenii. The evolutionary novelty of the subfamilies Hydrolithoideae, Metagoniolithoideae, and Lithophylloideae was the development of tetra/bisporangial conceptacle roofs by filaments surrounding and interspersed among the sporangial initials.

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 [+] [-]Bursa granularis (Röding, 1798) is a tonnoidean gastropod that is regarded as broadly distributed throughout the Indo-Pacific and tropical western Atlantic. Because of its variable shell it has received no less than thirteen names, now all synonymized under the name B. granularis. We sequenced a fragment of the cox1 gene for 82 specimens covering a large part of its distribution and most type localities. Two delimitation methods were applied, one based on genetic distance (ABGD) and one based on phylogenetic trees (GMYC). All analyses suggest that specimens identified as B. granularis comprise four distinct species: one limited to the tropical western Atlantic, another to southwestern Western Australia and two in the Indo-Pacific (from the Red Sea to the open Pacific) that are partly sympatric—but not syntopic—in Japan, the Philippines, Vanuatu and New Caledonia. Based on comparison of shell characters, we applied the following available names to the four species, respectively: B. cubaniana (d’Orbigny, 1841), B. elisabettae Nappo, Pellegrini & Bonomolo, 2014, B. granularis s. s. and B. affinis Broderip, 1833. We provide new standardized conchological descriptions for each of them. Our results demonstrate that a long planktotrophic larval stage, common among Tonnoidea, does not necessarily ensure a circumtropical species distribution.

Abstract [+] [-]Alpheus macrocheles (Hailstone, 1835), a species originally described from the northeastern Atlantic, has been reported from Brazil based on material from the north and northeast coasts and Espírito Santo. However, a thorough morphological comparison between Brazilian material reported as A. macrocheles and eastern Atlantic material of A. macrocheles revealed consistent differences, suggesting that the Brazilian specimens belong to an undescribed species. Alpheus ramosportoae sp. nov. is therefore now described based on material from Amapá to Pernambuco, Brazil. Morphological differences between the new species and A. macrocheles s. str. were supported by the clear divergence of 16S rRNA gene sequences (18% of genetic distance), separating the species in two distinct clades. Differences in the color pattern also were observed and illustrated.

Abstract [+] [-]The snapping shrimp Alpheus macrocheles (Hailstone, 1835b) is widely distributed across the Atlantic Ocean and was originally described from Hastings, England, based on a very brief description with limited morphological details and diagnostic illustrations. The morphologically similar A. amblyonyx Chace, 1972, type locality Quintana Roo, Mexico, is a western Atlantic taxon. The superficial description of A. macrocheles by Hailstone and the high similarity with A. amblyonyx has led to taxonomic confusion regarding the precise identification of these species. Thus, our objective was to reexamine these two species, based on a combined analysis of morphological—including a redescription for A. macrocheles and new morphological characterization of A. amblyonyx—and molecular data. In total, 42 morphological characters were analyzed, in addition to a phylogenetic analysis of 16S ribosomal RNA (rRNA) gene sequences. A Bayesian Inference analysis recovered A. macrocheles and A. amblyonyx as distinct clades supporting the taxonomic distinction between them. The tree topology suggests that A. macrocheles is more closely related to A. crockeri (Armstrong, 1941) and A. puapeba (Christoffersen, 1979) than to A. amblyonyx, which forms the sister group to a well-supported clade containing these three species. This contribution conclusively distinguishes between A. macrocheles and A. amblyonyx and points out the need for a comprehensive review involving all species of the larger A. macrocheles group.

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.

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 [+] [-]Eye reduction occurs in many troglobitic, fossorial, and deep-sea animals but there is no clear consensus on its evolutionary mechanism. Given the highly conserved and pleiotropic nature of many genes instrumental to eye development, degeneration might be expected to follow consistent evolutionary trajectories in closely related animals. We tested this in a comparative study of ocular anatomy in solariellid snails from deep and shallow marine habitats using morphological, histological, and tomographic techniques, contextualized phylogenetically. Of 67 species studied, 15 lack retinal pigmentation and at least seven have eyes enveloped by surrounding epithelium. Independent instances of reduction follow numerous different morphological trajectories. We estimate eye loss has evolved at least seven times within Solariellidae, in at least three different ways: characters such as pigmentation loss, obstruction of eye aperture, and “lens” degeneration can occur in any order. In one instance, two morphologically distinct reduction pathways appear within a single genus, Bathymophila. Even amongst closely related animals living at similar depths and presumably with similar selective pressures, the processes leading to eye loss have more evolutionary plasticity than previously realized. Although there is selective pressure driving eye reduction, it is clearly not morphologically or developmentally constrained as has been suggested by previous studies.

Abstract [+] [-]Intensive sampling of molluscs from the intertidal to depths of 800 m around the islands of Guadeloupe in the Lesser Antilles (KARUBENTHOS 2012, 2015) recovered 25 species of Lucinidae. All the Guadeloupe species are described and illustrated including details of larval shells and the taxonomy revised within the context of the wider western Atlantic fauna and recent classifications. Concurrent molecular analysis has helped separate frequently confounded species. ‘Myrtea’ pristiphora is placed in the Leucosphaerine genus Myrtina previously known from the Indo-West Pacific. A second western Atlantic species of Callucina, C. pauperatus previously known from the Pliocene of Jamaica is recognised from the southern Caribbean and off Brazil. The deeper water species ‘Myrteopis’ lens is placed in Afrolucina previously known from the eastern Atlantic. Lucinids commonly identified as Ctena orbiculata are shown to belong to two distinct species, C. orbiculata in the Gulf of Mexico and Florida and C. imbricatula in the Caribbean. Epicodakia is recognised for the first time in the western Atlantic with E. pectinata widely distributed across the region and E. filiata recorded from deeper water. Three species of Lucina are recognised, Lucina pensylvanica in the Gulf of Mexico and Florida and the similar Lucina roquesana from the Caribbean and Bahamas while the smaller L. aurantia has a wide distribution from central America to the Bahamas. A new species of Parvilucina, P. latens is described; this is similar to P. pectinella but has an internal ligament. The long problematic species ‘Codakia’ cubana is assigned to Ferrocina. A new genus, Guyanella is introduced for Parvilucina clenchi the smallest known lucinid. A critical reassessment of the lucinid fauna of the western Atlantic Ocean identifies 46 species for the region with 33 of these living at depths less than 200 m. Deeper-water habitats have been much less investigated except at sites of hydrocarbon seeps. Some species are widespread throught the whole region but others have more restricted ranges. Notable are species pairs, for example of Ctena, Lucina, Lucinisca and Parvilucina that are either largely Caribbean or Gulf of Mexico/Floridian in distribution. Although extralimital, two problematic species from the mid-south Atlantic island of St Helena are refigured and placed in Cavilinga.

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 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.
