Snapping shrimps of the genus Alpheus Fabricius, 1798 from Brazil (Caridea: Alpheidae): updated checklist and key for identification

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

“…This is the second record in the southwestern Atlantic, extending the southern distribution limit of this species from Bahia (13°56'22.0"S 38°55'35.4"W) to Campos Basin, northern Rio de Janeiro, Brazil (coordinates not available). The currently known range of A. peasei suggests a disjunct distribution pattern (see Soledade and Almeida, 2013). Christoffersen, 1979 ( Distribution: Western Atlantic -Brazil (Pará, Rio Grande do Norte, São Paulo to Rio Grande do Sul) and Uruguay (Christoffersen, 1979;1998; this study).…”

“…In Brazil, the genus currently comprises 33 species, several of which belong to species complexes (see Soledade and Almeida, 2013). However, the actual diversity of Brazilian fauna is still underestimated and requires a comprehensive review.…”

“…Among the Brazilian species, thirty-one occur in shallow water (less than 100 m in depth) and consist of tropical species, most of which are distributed in the western Atlantic, from North Carolina, Florida or West Indies to southern Brazil (Christoffersen, 1979;1982;Soledade and Almeida, 2013). This group presently contains 14 species with disjunct ranges, such as Alpheus formosus Gibbes, 1850, Alpheus peasei (Armstrong, 1940) and Alpheus verrilli (Schmitt, 1924), as well as Alpheus rudolphi Almeida & Anker, 2011, a recently described and little known species (Soledade and Almeida, 2013).…”

On the other hand, Alpheus pouang Christoffersen, 1979 and Alpheus puapeba Christoffersen, 1979 are subtropical species, presently ranging from southern Brazil to Uruguay and Argentina, respectively, occurring at depths from 45 to 268 m (Christoffersen, 1979;1982;Soledade and Almeida, 2013). In this study, we report range extensions of A.…”
