 Material examined: Brazil, São Paulo: 1 non-ovigerous specimen (cl 6.7 mm), MZUSP 30935, São Sebastião, Praia do Cabelo Gordo near CEBIMar, 23°49’35.85”S, 45°25’18.50”W, rocky intertidal, low tide (0.2 m tide), large tide pool among rocks, under very large rock on sand, dip-net, J.B. Mendonça, A. Anker, P.P.G. Pachelle coll., 31 October 2013.   
 Description: Rankin (1898) provided a very superficial description of S. ortmanni accompanied by a single general drawing; for a redescription and detailed illustrations see Anker (2007), and Schmitt (1936) and Anker (2010) for additional figures.   
 Colour in life: Semitransparent bright orange-yellow (Fig. 3).   
 Distribution: Caribbean Sea (e.g., Panama, Costa Rica), Bahamas, Bermuda (Anker, 2007, 2010); Brazil (Atol das Rocas and São Paulo) (Anker, 2007; present study).   
 Remarks: The single specimen from São Sebastião agrees well with the material from Atol das Rocas reported in Anker (2007). This specimen represents the first confirmed record of S. ortmanni in southern Brazil and also the first record of this species on the continental coast of Brazil. Anker (2007) stated that most Brazilian records and identifications of S. ortmanni before 2007 (e.g., Christoffersen, 1982, 1998) actually refer to S. carvachoi. The two species can be easily separated by the length and shape of the dactyli of the third to fifth pereiopods, as well as markedly different colour patterns (Anker, 2007, 2010; see also Fig. 3 and key below). In addition, most collecting records of S. carvachoi are from estuarine and mangrove habitats, indicating the species’ preference for soft sediments (Anker, 2007), with some specimens encountered in burrows of Alpheus estuariensis Christoffersen, 1984. In contrast, S. ortmanni appears to be associated with more saline, sand-rock or rubble-rock habitats, e.g., in Atol das Rocas and Panama (Anker, 2007, 2010), which is corroborated by the present specimen found under a large rock in the intertidal pool.
