Conquering new territories in the "new world": the alien shrimp Athanas dimorphus Ortmann, 1894 (Decapoda: Alpheidae) on the coast of Pernambuco, northeastern Brazil

ABSTRACT

The occurrence of the alien alpheid shrimp Athanas dimorphus Ortmann, 1894 is reported for the first time for the state of Pernambuco, northeastern Brazil, based on two ovigerous females collected at Praia do Paraíso, near the Suape Harbor (08º21'29.9"S 34º57'00.9"W). The species, native from the Indo-West Pacific region, was previously reported from two other Brazilian states (Ceará and São Paulo), also occurring in localities with nearby harbors. The presence of ovigerous females suggests that the species was successfully introduced into the area. The main possible introduction vectors for A. dimorphus in Pernambuco and the dispersal potential of the species along the Brazilian coast are discussed.
