Material examined. Curaçao: 2 non-ov. individuals ( VIMS 08CU3002–3), Caracas Baai, from the canals of Agelas cf. clathrodes . 2 ov. females, 2 non-ov. individuals ( VIMS 08CU12401, 13002), Eastpunt, from the canals of A. cf. clathrodes . 1 individual ( VIMS 08CU12203), Eastpunt, from the canals of Hyattella intestinalis . 1 ov. female, 1 non-ov. individual ( VIMS 08CU504–5), Piscadera Baai, from the canals of H. intestinalis . 1 ov. female, 2 non-ov. individuals ( VIMS 08CU9801), Piscadera Baai east, from the canals of Aiolochroia crassa . 1 individual ( VIMS 08CU8203), Scary Steps, from the canals of A. cf. clathrodes . 1 individual ( VIMS 08CU2801), St. Michiel Baai, from the canals of A. crassa . 1 ov. female ( VIMS 08CU5608), 1 non-ov. individual ( VIMS 08CU5609), Westpunt, from the canals of H. intestinalis . Largest ov. female, CL 3.1, largest non-ov. individual, CL 3.9 mm.

Color. Individuals found in Curaçao typically had a brightly colored major chela, with distal red tips, a white crescent, and the rest of the chela proximal to the white crescent blue ( Plate 5B View PLATE 5 ). This “red white and blue” color morph has also been described from specimens collected from Belize and Caribbean Panama ( Rios & Duffy 2007). Ovigerous females tended to have more drab coloration on the major chela, and had yellowish-green embryos.

Hosts and ecology. In Curaçao, S. mcclendoni was typically found in equal sex ratios and occurred in low frequencies across three different sponge hosts ( Agelas cf. clathrodes , Hyattella intestinalis , and Aiolochroia crassa ).

Distribution. Florida ( Coutière 1910); Bahamas ( Dardeau 1984); Cuba ( Martínez Iglesias & García Raso 1999); Yucatan peninsula of Mexico ( Chace 1972); Caribbean Panamá ( Duffy 1992), Belize ( Rios & Duffy 2007), Jamaica ( Macdonald et al. 2009); Curaçao (this study).

Remarks. S. mcclendoni can be distinguished from its morphologically closest relative ( S. sanctithomae ) on the basis of its curved major chela fingers (not curved in S. sanctithomae ) and the broad fan of plumose setae on the distal margin of the telson (typically containing <6 setae in S. sanctithomae ).
