Further record of Trachypenaeopsis mobilispinis (Rathbun) (Decapoda, Penaeidae) from Brazilian coastal waters

Abstract

In the Brazilian fauna, the Dendobranchiata are represented by 7 families, 26 genera, and 61 species (D’Incao, 1995a). During the 1990s the species, Aristeus antillensis A. Milne-Edwards & Bouvier, 1909, Aristaeopsis edwardsiana (Johnson, 1867), Benthesicymus bartletti Smith, 1882, Sicyonia stimpsoni Bouvier, 1905, Sergestes armatus Kroyer, 1855, S. corniculum Kroyer, 1855, Sergia prehensilis (Bate, 1881), and S. regalis (Gordon, 1939) were collected during the project “Recursos Vivos da Zona Economica Brasileira (REVIZEE)” carried out along the Brazilian coast (Ramos-Porto et al., 2000; Santos et al., 2002; Silva et al., 2002; Cardoso & Serejo, 2003). Yet, three non-indigenous, introduced shrimp species can be found in Brazil, i.e., Penaeus monodon Fabricius, 1798, Metapenaeus monoceros (Fabricius, 1798) (both Indo-West Pacific), and Litopenaeus vannamei (Boone, 1931) (eastern Pacific) (Fausto Filho, 1987; D’Incao, 1995b; Santos & Coelho, 2002; Tavares & Mendonca, Jr., 2004). The shrimp, Trachypenaeopsis mobilispinis (Rathbun, 1915) was described by Rathbun (1915) as Metapenaeus mobilispinis from 14 individuals collected at Saba Island in the Dutch West Indies, situated in the northern half of the Windward Islands. This material was dredged over a stony bottom about 4 fathoms (approx. 6 m) deep. Burkenroad (1934) examined material of M. mobilispinis from the Turks Islands, Bahamas, deposited at the American Museum of Natural History. He transferred the species to the new genus, Trachypeneopsis [sic] and extended the known range of the species to the north. Further records of T. mobilispinis were provided by Chace (1972) from Barbuda and Saint Christopher, collected during the Smithsonian-Bredin Caribbean Expeditions, and dredged between 7 and 8 m. Chace (1972) also mentioned its occurrence
