A new species of Trichopeltarion A. Milne-Edwards, 1880, is described from off coast of Brazil, namely Trichopeltarion pezzutoi n. sp. The new species is compared to its Atlantic congeners, Trichopeltarion nobile A. Milne-Edwards, 1880, and Trichopeltarion intesi (Crosnier, 1981). The record of T. nobile from Brazil should actually be attributed to T. pezzutoi n. sp. The differences between the genera Trichopeltarion and Peltarion Jacquinot, 1847 are discussed.

A new species of scaly blenny, Labrisomus conditus sp. n., is described from Fernando de Noronha Archipelago, off northeastern Brazil. It differs from its Western Atlantic congeners by the following combination of characters: nuchal cirri when depressed not reaching dorsal-fin origin, 68 to 73 lateral line scales, first and second dorsal-fin spines slightly shorter than third spine and not flexible, numerous pale dots overall (light blue in life), opercular dark spot with incomplete and diffuse broad pale margin (orange in life). The new species is a territorial bottom-dweller in rocky shores and is found among algae and in crevices at depths from 0.5 to 6 m. Labrisomus conditus sp. n. feeds mostly on crustaceans (crabs, amphipods) and molluscs (snails, bivalves). The new species increases to five the species within the genus Labrisomus recorded from Southwestern Atlantic.

This work deals with haplosclerid sponges off the coast of Maranhão State, northeastern coast of Brazilian shelf (southwestern Atlantic). A new species is described, Haliclona (Halichoclona) lernerae. Four species are recorded for the first time for the Brazilian coast: Amphimedon caribica (Pulitzer-Finali, 1986); Niphates lutea Lehnert & Van Soest, 1999; Neopetrosia subtriangularis (Duchassaing, 1850) and Petrosia (Petrosia) weinbergi Van Soest, 1980. Three species were recollected from the southwestern Atlantic and have their geographic distribution extended on the Brazilian coast: Callyspongia (Cladochalina) vaginalis (Duchassaing & Michelotti, 1864), Oceanapia bartschi (De Laubenfels, 1934) and Xestospongia muta (Schmidt, 1870). Two species were collected for the first time from the Maranhão State Coast: Niphates erecta Duchassaing & Michelotti, 1864 and Neopetrosia proxima (Duchassaing & Michelotti, 1864). A taxonomic study of those samples is given, including description, illustrations and geographic distribution.

The present study reports three species of Farrea Bowerbank, 1862 from Campos Basin (southwestern Atlantic): Farrea herdendorfi Duplessis and Reiswig, 2004, Farrea occa Bowerbank, 1862, and Farrea campossinus sp. nov. This is the first record of F. herdendorfi for the South Atlantic and only the second record of the species worldwide. Farrea occa is described and reported to form mass occurrences in the area’s sponge and coral banks, as seen in extensive video recording undertaken between 900 and 1100 m depth. The new species approaches Farrea foliascens Topsent, 1906 very closely, but differs in that its hooked anchorate clavules are much larger and the meshes of its dictyonal framework rather more irregular. Our thoughts on whether the proposed new species deserved species or subspecies rank led to an investigation on the usage of subspecies rank in Porifera. A historical overview, mainly contrasting Demospongiae and Hexactinellida is offered here. We concluded that no rule of thumb is readily made out from the comparative analysis of various authors’ taxonomic decisions. Until one such agreement is achieved, it appears to us that naming new subspecies should be objectively argued for, or better, totally avoided, as a useless further dimension to taxonomic uncertainty in poriferan classification.

A new species of the deep-water crab genus Chaceon Manning & Holthuis, 1989 (Geryonidae Colosi, 1923), is described from southwestern Atlantic. It is the ninth species of the genus known from the western Atlantic. It is most closely related to C. eldorado Manning & Holthuis, 1989, C. notialis Manning & Holthuis, 1989, and C. ramosae Manning, Tavares & Albuquerque, 1989, from which it can be readily differentiated in having the dactyli of P2-P5 laterally compressed, instead of being dorsoventrally depressed. A key to the western Atlantic species of Chaceon is provided.

A new species of Dragmaxia Hallmann, 1916 is described from the northern sector of the S o Paulo state coastline (Brazil), in the Tropical southwestern Atlantic. The new species, Dragmaxia anomala sp.n., differs from the other species of the genus, viz. D. variabilis (Whitelegge, 1907) and D. undata Alvarez et al., 1998, due to its raphides which are not acanthose.

A new species of chiton is described from early Miocene deposits of the Monte León Formation, in Santa Cruz Province, Argentina. Callochiton monteleonensis n. sp. clearly differs from known fossil and Recent species of the southwestern Atlantic because the central area of its intermediate valves has a stepped appearance, in which each step is marked by a longitudinal rib. It is similar to Callochiton kapitiensis Mestayer, 1926, a Recent species from New Zealand. Biogeographic implications are discussed. This is the first record of a polyplacophoran from Neogene deposits of Argentina.

A new species of deep-water brachyuran crab, Euphrosynoplax dincao, from southeastern Brazil is described and illustrated. The genus Euphrosynoplax currently consists of two species, E. clausa Guinot, 1969, and E. campechiensis Vázquez-Bader & Gracia, 1991, both only known from the Gulf of Mexico. The new species can be easily separated from its northern counterparts by a suite of carapace and appendage characters. Euphrosynoplax campechiensis is recorded for the first time from the Caribbenan Sea (Guadeloupe and between Saint Kitts and Nevis).
