Material examined. 1 n-ov. female, Ilha de Santa Bárbara (17°57’28”S 38°42’19”W), coll. R.M.C. Barbosa & L.M. Fernandes, 31.viii. 2013, 11 m, in sponges, UESC 1559; 1 n-ov. female, same collection data, in dead coral rubble, UESC 1560; 1 n-ov. female, Ilha de Santa Bárbara (17°57’31”S 38°42’16”W), coll. R.M.C. Barbosa & L.M. Fernandes, 03.ix. 2013, 9 m, in sponges, UESC 1561.

Distribution. Western Atlantic—Gulf of Mexico (off Texas), Caribbean Sea (Yucatan Peninsula to Venezuela) and Brazil (Atol das Rocas, Ceará, Alagoas, Bahia to São Paulo) (Coutière 1909; Chace 1956; Anker et al. 2012).

Previous records from Abrolhos. None.

Remarks. Although S. antillensis is reported from Abrolhos for the first time, part of Christoffersen’s (1979) material of S. minus (Say, 1818) from Brazil (including Abrolhos) may correspond to S. antillensis (Anker et al. 2012) . The morphology and color pattern of our material agrees very well with the illustrations and descriptions provided by Anker et al. (2012). A color photograph of a specimen from the Bahia coast was provided by Santos et al. [2012: 153, fig. 4D, as “ S. brevicarpus (Herrick, 1891) species complex”].
