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

Abstract

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. © 2016 The Author(s).
