Thirteen species of the Western Atlantic genus Hypoplectrus (Serranidae) are currently recognized, two of which are described as new. Hypoplectrus maya n. sp. (Maya hamlet) is restricted to the coastal lagoon of the Meso-American Barrier Reef system in Belize. It is a solid iridescent blue, lacks nose spots and lacks black margins on fins. Hypoplectrus randallorum n. sp. (Tan hamlet) is found widely in the central and western Caribbean. Its color varies from light brown to tan and it has spots on the nose, at the base of the pectoral fin and occasionally on the upper part of the caudal peduncle. All identified species of Hypoplectrus are illustrated in live coloration along with examples of color variations in H. nigricans and H. unicolor. A historical review of Hypoplectrus is included with a discussion of issues concerning their taxonomy.

A New Species

A new species of hermit crab, Areopaguristes tudgei, family Diogenidae, is fully described and illustrated, including acolor photograph. A dense population of this new species was discovered living intertidally in a concealed habitat undercoral boulders covered with calcareous algae, on the crest to fore-reef zone in Carrie Bow Cay, a small island located onthe western Caribbean Mesoamerican Barrier Reef of Belize. This new species, the 24rd of Areopaguristes Rahayu &McLaughlin, 2010, and fourth known in this genus from the western Atlantic, is superficially similar to those of thePaguristes tortugae complex. As in species of that complex, A. tudgei n. sp. has dense plumose setation on the chelipeds,and at least in females, a fringe of plumose setae on the dorsolateral margins of the chelae, and on the dorsal margins ofthe walking legs. The presence in A. tudgei n. sp. of this setal arrangement, previously considered the only definingcharacter of the P. tortugae complex, can be attributed to convergence. The new species is contrasted with all other westernAtlantic congeners, and a key is presented to aid in their identification. A list of all western Atlantic species of Paguristes sensu lato and their current generic assignments is included.

Substrate Types

In the framework of a research on taxonomy and ecology of selected families of polychaetes conducted at the field station of the Smithsonian Institution (Washington DC, USA) at Carrie Bow Cay (Belize, Western Caribbean Sea) on November 2005, several qualitative benthic samples from different habitats and substrate types (Thalassia testudinum shoots, fragments of dead hard corals, sponges) have been analyzed. In some of these samples, specimens of Sabellidae were found, revealing, together with some taxa already known for the area, the presence of two new species, Megalomma fauchaldi sp. nov., and Pseudoaugeneriella spongicola sp. nov., this latter representing a genus newly reported from the Caribbean. Sabellidae biodiversity and systematics between Caribbean and Mediterranean regions is also compared.

Species Being

Seven species of the moruminine harpid genus Morum (sensu stricto) are now known to occur within the Tropical Western Atlantic Region, with three species being restricted to the Caribbean Molluscan Province and four species being restricted to the Brazilian Molluscan Province. The Caribbean Molluscan Province contains Morum oniscus, M. purpureum, and M. strombiforme, while the Brazilian Molluscan Province contains M. bayeri, M. berschaueri, and two new species, Morum damasoi n. sp. and Morum mariaodeteae n. sp., which are described here.

Two new species of Terebrasabella Fitzhugh & Rouse, 1999 are described from eastern Australia. Terebrasabella hutchingsae sp. nov., was found from preserved coral rock debris collected in 1977 on the outer Barrier Reef near Lizard Island, Queensland. Terebrasabella fitzhughi sp. nov., was found alive in burrows in and among spirorbin serpulid tubes on intertidal rocks in Tasmania in 1996. Both species were found in mucoid tubes, and brood their young in a manner similar to the only other described species of Terebrasabella, T. heterouncinata Fitzhugh & Rouse, 1999. Terebrasabella hutchingsae sp. nov., is exceptional as it possesses a type of thoracic neurochaetal uncinus different from the other two species, and which is similar to the notochaetal acicular “palmate hook” seen in Caobangia. Descriptions of both species are given, and the diagnosis for Terebrasabella is emended. Larval and chaetal morphology and relationships among of the three known Terebrasabella spp. are discussed.

The earliest known members of the Thais clade of rapanine muricid neogastropods comprise four species from the Cantaure Formation (early Miocene: Burdigalian) of Venezuela; three of these species are new. Neorapana rotundata Gibson-Smith et al., 1997, is most closely related to the Recent Pacific Mexican N. tuberculata (Sowerby, 1835), and represents the only known Atlantic occurrence of the genus. Thais brevicula new species is closest to T. callaoensis (Gray, 1828) from the Recent of northern Peru and the Galápagos. A review of the genus Thais indicates that the typical members of this group occur in the South Atlantic, West Africa, and eastern Pacific, but not in the Recent fauna of the southern Caribbean. Stramonita bifida new species is a large species related to the Recent S. haemastoma floridana (Conrad, 1837), which occurs throughout the Caribbean. A review of American species of Stramonita indicates that the taxon S. biserialis (de Blainville, 1832) from the Recent fauna of the eastern Pacific, and the taxon S. h. haemastoma (Linnaeus, 1767), may each be composed of more than one species despite the teleplanic dispersal of their larvae. Stramonita semiplicata new species is closely related to the Recent S. bicarinata (de Blainville, 1832) from the South Atlantic, and represents a lineage that occurred in the Caribbean region until at least the late Miocene. It may have given rise to the eastern Pacific genus Acanthais. The higher diversity and greater antipredatory specialization of eastern Pacific as compared to western Atlantic members of the Thais clade may have resulted from higher post-Miocene rates of speciation and lower extinction rates in the eastern Pacific.

Two new species belonging to the precious coral genus Corallium were collected during a series of exploratory cruises to the New England and Corner Rise Seamounts in 2003–2005. One red species, Corallium bathyrubrum sp. nov., and one white species, C. bayeri sp. nov., are described. Corallium bathyrubrum is the first red Corallium to be reported from the western Atlantic. An additional species, C. niobe Bayer, 1964 originally described from the Straits of Florida, was also collected and its description augmented.

Two new species of Selenops, S. anacaona sp. nov. (♀) and S. caonabo sp. nov. (♀), are described from the Dominican Republic on the Caribbean island of Hispaniola. These two new species increase the number of endemic Selenops on Hispaniola to 13, surpassing Cuba, which currently has 11 endemic species. Additionally, the male of S. pensilis Muma, 1953 from Hispaniola is described, as well as the male of S. petrunkevitchi Alayón, 2003 from Jamaica. Full distribution records are given for the new species and the newly described males, and new records are provided for the following species: S. aequalis Franganillo, 1935, S. bocacandensis Crews, 2011, S. candidus Muma, 1953, S. micropalpus Muma, 1953, S. morro Crews, 2011, S. simius Muma, 1953, S. souliga Crews, 2011, and S. submaculosus Bryant, 1940.

A New Species

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