Salmoneus carvachoi Anker, 2007: 27 , fig. 3.

Material examined. 1 ni, 01.VIII.2008, Cairú, Triana River, Boipeba Island, MZUESC 1272; 1 f, 18.VIII.2007, Maraú, Tanque Island, T2, MZUESC 1108; 2 ni, 08.V.2008, Una, Comandatuba Village, MZUESC 1250; 2 ni, 06.V.2008, Canavieiras, Pardo River, MZUESC 1220; 1 ni, 08.III.2008, Santa Cruz Cabrália, João de Tiba River, near Santo André Beach, MZUESC 1171.

Distribution. Western Atlantic—Mexico (Yucatan), Guadeloupe and Brazil (Paraíba, Pernambuco, Bahia , São Paulo and Paraná) ( Anker 2007; 2010).

Ecological notes. Intertidal areas in estuaries, in burrows in mud, under rocks and rubble. Salinity range: 24–35 psu. Depth range: intertidal to 22 m [ Christoffersen 1982, as S. ortmanni ( Rankin, 1898) ; Anker 2007]. Several specimens of S. carvachoi were found in association with burrows of Alpheus estuariensis ; this was also observed by Ramos-Porto et al. (1994, as S. ortmanni ).

Previous records. Camamu Bay ( Almeida et al. 2007b, as Salmoneus cf. ortmanni ).

Remarks. Salmoneus carvachoi was initially reported from Brazil as S. ortmanni ( Christoffersen 1982; Ramos-Porto et al. 1994). The material from Camamu Bay (see Almeida et al. 2007) was re-examined and all diagnostic characters of S. carvachoi were readily recognized in these specimens, confirming its occurrence in Bahia . The occurrence of S. ortmanni in Brazil is presently restricted to Atol das Rocas ( Anker 2007).
