Remarks. Salmoneus depressus can be easily recognised by the dorsally indented carapace, a feature shared only with its Pacific sister species, S. excavatus Anker, 2011 ( Anker 2011) . The species appears to be widespread in the western Atlantic, with records from Panama (Bocas del Toro, San Blas Islands), Mexico (Gulf of Mexico), Cuba (Isla de la Juventud) Venezuela (Isla Margarita), Saint Martin, Barbados and Brazil (São Paulo) ( Anker 2011; Anker et al. 2013; Duarte et al. 2014; present study). The present material is the first record of the species from Cuba (Isla de la Juventud) and a new locality in the Gulf of Mexico (Isla de Enmedio).
