Snapping shrimps of the genus Alpheus (Caridea: Alpheidae) from Brazil: range extensions and filling distribution gaps

ABSTRACTThe objective of this study is to report new occurrences of five species of snapping shrimps of the genus AlpheusFabricius, 1798 in Brazil and, thus, contribute to the knowledge of their zoogeography. The southern limit of distribution of A. formosus Gibbes, 1850 and A. peasei (Armstrong, 1940) is extended from Paraná to Santa Catarina and from Bahia to Rio de Janeiro, respectively. The northern distribution limit of A. pouang Christoffersen, 1979 and A. verrilli (Schmitt, 1924) is substantially extended from São Paulo to Pará and from Bahia to Pará, respectively. Finally, A. rudolphi Almeida & Anker, 2011, previously known from Ceará and Alagoas, is recorded for the first time in Pernambuco, filling a gap in its known distribution.
