Alpheus verrilli ( Schmitt, 1924)

( Fig. 3 E)

Material examined. 1 male, Ilha de Santa Bárbara (17°57’49”S 38°41’53”W), coll. GO. Soledade, 03.ix.2013, intertidal, under rocks, UESC 1557.

Distribution. Western Atlantic—Florida, Belize, Panama, Barbados and Brazil (Bahia, Rio de Janeiro, São Paulo) (Anker 2012; this study).

Previous records from Abrolhos. None.

Remarks. The presently known distribution of A. verrilli in the western Atlantic is disjunct between the Caribbean-Florida region and southeastern Brazil (Rio de Janeiro and São Paulo), with no records in-between (Anker 2012; Soledade & Almeida 2013). The single Abrolhos specimen represents the first record of A. verrilli for Bahia, extending significantly northwards its previously known Brazilian range. However, according to Anker (2012), the Brazilian specimens differ from the Panamanian and Florida specimens in some features of the color pattern, e.g., the orange-yellow antennular and antennal flagella, and therefore, the taxonomic status of the Brazilian material of A. verrilli requires confirmation. The Abrolhos specimen has a very similar coloration to the specimen from São Paulo in Anker (2012).
