Authorship SCIMAGO INSTITUTIONS RANKINGS

Abstract

Three caridean shrimps have their distribution range extended on the Brazilian coast. Alpheus carlae Anker, 2012 (Alpheidae), previously reported from Ceará to São Paulo, and Typton fapespae Almeida, Anker & Mantelatto, 2014 (Palaemonidae), previously known only from Rio de Janeiro and São Paulo, are both now reported from Santa Catarina, the new southernmost record of these species in the Atlantic Ocean. Athanas nitescens (Leach, 1813) (Alpheidae), an invasive species from the eastern Atlantic first reported from São Paulo in 2012 based on a single male, is now confirmed to have established populations in Brazil with the finding of ovigerous females on the coast of Rio de Janeiro. Illustrations for all three species are provided based on the new material.
