Largest ov. female, CL 3.9 mm, largest non-ov. individual, CL 3.2 mm. Color. Body typically orange, sometimes with orange-tipped chelae; females with ovaries ranging from green to greenish-brown and embryo color ranging from orange, to green, to olive-brown. Hosts and ecology. In Curaçao, Synalpheus sanctithomae is found in a range of different sponges, most commonly in Agelas cf. clathrodes , Hyattella intestinalis, Hymeniacidon caerulea, and Xestospongia subtriangularis, typically in heterosexual pairs. In Belize, S. sanctithomae is found in A. cf. clathrodes , H. intestinalis, and H. caerulea (Macdonald et al. 2006). Distribution. Florida (Gore 1981); Virgin Islands (Coutière 1909); Belize (Macdonald et al. 2006; Rios & Duffy 2007); Jamaica (Macdonald et al. 2009); Curaçao (this study); Brazil (Christofferson 1979). Remarks. Although Synalpheus sanctithomae has been distinguished from the closely related species Synalpheus mcclendoni by the number of distal telson setae (10 or more in S. mcclendoni, <6 in S. sanctithomae; Rios & Duffy 2007), this character varied slightly in S. sanctithomae collected in Curaçao (2–7 distal telson setae), sometimes among individuals inhabiting the same individual sponge. In addition, some individuals had a row of setae on the dactyl of their major chela.
