J.B. Mendonça, 10.vii.2015; 2 males, 2 ovig. females, MZUSP 34137, same collection data; 2 males, 1 ovig. female, OUMNH.ZC. 2016.02.0 17, same collection data. Size of largest male: cl 3.8 mm ( MZUSP 34139); largest female: cl 3.5 mm ( MZUSP 34144).

Additional (extra-limital) material examined. Brazil: 1 male, 1 ovig. female, MZUSP 32025, REVIZEE— Comissão Central sta. 7BT(025), Rio de Janeiro, off Macaé, Almirante Saldanha Seamount, 22º23’S – 37º35’W, depth: 105 m, 08.ii.1996.

Description. See Coutière (1909) for original description and illustrations, Christoffersen (1979) for additional figures, and Ríos & Duffy (2007) for a colour photograph.

Distribution. Western Atlantic: Florida; throughout Caribbean Sea; Brazil: Pernambuco to Bahia, Atol das Rocas , Almirante Saldanha Seamount, Trindade Island ( Christoffersen 1979; Gore 1981; Rodríguez 1986; Ríos & Duffy 2007; present study).

Ecology. Coral reefs and other hard bottom habitats rich in porous rocks, clumps of calcareous algae, sponges; obligate associate of a variety of sponges (e.g., in the western Caribbean Sea: Hymeniacidon, Agelas , Hyattella , Lissodendoryx ) ( Ríos & Duffy 2007); typical depth range: 1–20 m, exceptionally to 105 m (present study).

Remarks. Synalpheus sanctithomae is a relatively distinctive species of the S. gambarelloides group, most easily recognisable by a short rostral carina and the presence of a distinct bump on the mesial side of the major chela pollex. The present material extends the previously known southern distribution limit of S. sanctithomae from Bahia southeastwards to Trindade Island off Espírito Santo and further south to Almirante Saldanha Seamount off Rio de Janeiro.
