Material examined:Thirty-nine specimens; 4 from site 1 (1 female not properly oriented to be measured, and 3 specimens of unknown gender, 89–127 µm long); 17 from site 2 (9 females, 105–180 µm long, 1 male, 79 µm long, 6 specimens of unknown gender, 74–155 µm long, and 1 two-clawed larva 44 µm long); 1 female from site 3 (89 µm long); 2 females from site 5 (106 and 181 µm long); 3 females from site 6 (133–176 µm long); 2 females from site 7 (119 and 124 µm long); 8 from site 11 (2 females, 120 and 182 µm long, and 6 specimens of unknown gender, 120–178 µm long); and 2 from site 12 (one female 209 µm long and a specimen of unknown gender not measured).
Remarks:The specimens match the description of the species in Schulz (1955). This species is widely distributed in both intertidal and subtidal sand. Although it has been reported from both Brazil( Moura et al.2009) and the North Atlantic ( Morgan & O’Reilly 1989, Hansen et al.2001), it has never been reported from the Bahamas, the USAor the Caribbean (Kaczmarek et al.2015).
