Distribution of two species of Nephropsis Wood-Mason, 1872 (Crustacea, Decapoda, Nephropidae) from northeastern Brazil

The genus Nephropsis Wood-Mason, 1872 has been reported from Brazil by Tavares (1998), Tavares & Young (2002), Silva et al. (2003), Dall´Occo et al. (2007) and Serejo et al. (2007), recording Nephropsis aculeata Smith, 1881, N. rosea Bate, 1888 and N. agassizii A. Milne-Edwards, 1880, the last of which occurs in both northeastern and southeastern of Brazil.

New records of deep-sea prawn of the genus Gennadas Spence Bate, 1881 (Crustacea: Decapoda: Benthesicymidae) from Southwestern Atlantic

Here, we report the new occurrences of four deep-water prawn of the genus Gennadas in the southwestern Atlantic: G. gilchristi recorded from the Mid-Atlantic Ridge region; G. capensis recorded from Brazilian waters off Fernando de Noronha Archipelago, Atol das Rocas and Ceará Chain; G. talismani and G. scutatus recorded both to Mid-Atlantic Ridge and to Brazilian waters.

New Records of Two Deep-Sea Crabs of the Family Lithodidae Samouelle, 1819 (Crustacea: Decapoda) in the Southwestern Atlantic

Species in the family Lithodidae Samouelle, 1819 are benthic and occurring mostly on muddy substrates of continental and insular slopes in cold waters worldwide. The 28 lithodid species presently recorded from the Atlantic Ocean: seven species of Lithodes Latreille, 1806, five of Neolithodes A. Milne-Edwards and Bouvier, 1894 and 16 of Paralomis White, 1856. Four species are occuring off Brazil, Lithodes manningi Macpherson, 1988 and Lithodes confundens Macpherson, 1988 are the only two species of the genus reported from Brazilian waters, between the states of Bahia and Santa Catarina, while Neolithodes only has two species recorded from Brazil, Neolithodes agassizii (Smith, 1882) from Bahia to Rio de Janeiro, and N. aff. Asperrimus Barnard, 1947 from the state of Santa Catarina. Here we report Lithodes manningi Macpherson, 1988 and Neolithodes agassizii (Smith, 1882) from the Potiguar Basin off northeastern Brazil.

New records of deep-sea shrimps of family Solenoceridae Wood-Mason & Alcock, 1891 (Crustacea: Decapoda: Dendrobranchiata) from Southwestern Atlantic

This paper reports the occurrence of four deep waters shrimps of the family Solenoceridae in the southwestern Atlantic, Brazil. The rare Hadropenaeus modestus is collected for the second time from Brazilian waters after 138 years, filling the gaps on its distributional pattern. Mesopenaeus tropicalis is a new register for Potiguar basin, although it is common along Brazilian coast. Hymenopenaeus chacei and H. laevis are recorded for the first time in southwestern Atlantic. The records of these species in the southwestern Atlantic are an important advancement to raise the knowledge of the deep-sea shrimps.
