Description. For description and illustrations see Coutière (1909) and Williams (1984); illustrations of a

Size range. Males, 2.8–3.7 mm cl; females, 2.9–3.3 mm cl; specimens from a Brazilian offshore oil platform (MZUSP 25344) significantly larger: largest female at 4.8 mm cl, largest male at 4.3 mm cl.

Colour in life. Semitransparent with greenish tinge and scattered reddish chromatophores grouped into a more conspicuous red band between the eyes; major chela palm distally greenish, dactylus mostly colourless with greenish-yellow margin; eggs greenish ( Fig. 46 View FIGURE 46 ).

Type locality. South of Cape San Blas , Florida   .

Distribution. Western Atlantic: North Carolina to Florida and Texas; Gulf of Mexico; Bermuda; Caribbean Sea (e.g., Honduras, Panama, Jamaica, Curaçao, Barbados); Brazil: Ceará, Atol das Rocas, Alagoas, Espírito Santo, Rio de Janeiro (e.g., Chace 1972; Williams 1984; Christoffersen 1979, 1998; McClure 2005; Bezerra & Coelho 2006; present study; see map in Fig. 52 View FIGURE 52 ).

Ecology. Lower intertidal to 102 m ( Williams 1984); known from a variety of microhabitats, such as crevices of sabellariid reefs ( Phragmatopoma   ), living and dead corals (e.g., Oculina   , Porites   , Siderastrea   , Mussismilia   ), sunken wood perforated by shipworms, sponges, including Agelas clathrodes   , Ircinia strobilina   , Ircinia sp.   ( Rouse

1970; Gore et al. 1978; Rodríguez 1980; Reed et al. 1982; Duffy 1992; present study); and colonial ascidians, Didemnidae   ( Fig. 35e View FIGURE 35 ); a single report of a very unusual association with the crinoid Davidaster rubiginosus   by Criales (1984) requires confirmation; typically in heterosexual pairs.

Remarks. The present material differs from the typical S. townsendi   , as illustrated by Coutière (1909), only slightly, e.g., by the distal tooth on the major chela palm very slightly curving down and the third pereiopod propodus armed with only six spiniform setae on the ventral margin.
