Halechiniscus perfectus Schulz, 1955

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 USA or the Caribbean (Kaczmarek et al. 2015).
