Four portunid crabs species, including an exotic one, are recorded for the first time from the state of Sergipe, NE Brazil. Although common along the Brazilian coast, the new records of the crabs Callinectes bocourti A. Milne-Edwards, 1879, C. exasperatus (Gerstaecker, 1856), C. marginatus (A. Milne-Edwards, 1861) and Charybdis hellerii (A. Milne-Edwards, 1867) (Decapoda, Brachyura, Portunidae) reflect the poor knowledge about crustacean fauna in the state of Sergipe, and reinforce the need for systematic surveys to better understand the local biodiversity.

“…Lists of alien decapod crustaceans known from Brazil have been published recently (Tavares and Mendonça Jr 2004;Pachelle et al 2011;Tavares 2011). With the addition of A. nitescens reported here, the number of nonindigenous decapods that have been reported in marine, brackish, and fresh waters of Brazil rises to 21.…”

“…Penaeus monodon has been cultivated in Table 1 Characters useful for distinguishing the shrimps Athanas dimorphus Ortmann, 1894 and A. nitescens (Leach, 1813[in Leach 1813-1814 the Mediterranean, and it is possible that the mode of introduction is identical to that of the first two species. Of these, only C. hellerii is considered well established in Brazil, based on its reproductive and population performance (Mantelatto and Garcia 2001;Tavares 2011). Of the five species mentioned above, only A. dimorphus might have been transported transoceanically on ship hulls.…”

“…Discovery of the true mechanism of introduction of A. dimorphus is a difficult task, because Brazil has neither facilities aiming for early detection of exotic species nor a long-term monitoring program of marine invasions (Fernandes et al 2009). Collection of alien species is often a by-product of ecological and survey studies performed by Brazilian researchers (Tavares 2011), as well as residents of different regions. The present records were made as part of a long-term project on the taxonomy of decapod crustaceans along the São Paulo coast.…”

“…However, the possibility remains that these shrimps crossed this biological filter through accidental transport, such as in ballast water, as previously recorded for other species of decapod crustaceans (e.g., Mantelatto & Dias 1999;Alves et al, 2006;Tavares, 2011). …”

New records of caridean shrimps, Lysmata ankeri and L. cf. intermedia, from southeast coast of Brazil

Background: The genus Lysmata includes about 40 described species of which at least 12 species occur in the western Atlantic. The present study records the extension of the southern limit of distribution of two species of Lysmata to the coast of São Paulo. Results: A total of 17 and two individual of Lysmata ankeri and Lysmata cf. intermedia were sampled, respectively. Lysmata ankeri were observed inhabiting crevices and natural burrows formed by rocks from 5 to about 15 m depth, while Lysmata cf. intermedia were found living under a large rocky plate from 8 meters depth. Conclusions: These new records improve our knowledge about the geographical distribution of Lysmata ankeri and Lysmata cf. intermedia. The expansion of the geographical distribution of these species may be caused by two different mechanisms of larval dispersal, either natural or anthropogenic.
