Portunus (Achelous) sebae. — Rathbun, 1901: 46; 1920: 16; 1930: 79, pls. 35, 35; 1936: 383; Ng et al. 2008: 151.
Achelous sebae. — Smith, 1869: 34; Verrill 1908: 380, fig. 27; Mantelatto et al. 2018: 193, fig. 1; Poupin 2018: 205, fig. 228; Koch et al. 2022: 13, fig. 5.
Distribution. Western Atlantic: St. Thomas, St. Martin, Guadeloupe, Dominica, Martinique, Barbados, Isla de Blanquilla, Isla de Margarita, Tortuga, Bonaire, Curaçao, and Aruba (Poupin 2018; present study).
Material examined. Barbados, Batts Rock, St. Michael, subtidal, 13°08’04.81”N, 59°38’12.30”W, 1 ♀ (juv.) CW: 16.1 mm (BLSZ 027). Port St. Charles, St. Peter, subtidal, 13°15’51.81”N, 59°38’36.34”W, 1 ♀ CW: 56.6 mm (BLSZ 245).
Remarks. This is the first record of Achelous sebae for Barbados. Caught in crab traps placed on sandy bottoms (~ 4 m deep) on the west coast of Barbados. Achelous sebae can be identified by the presence of two ocelli on the mesobranchial surface of the carapace, which fade slightly in preserved specimens; frontal margin with six triangular shaped teeth, median pair larger than submedian pair, lateral pair with spine at the tip; anterolateral teeth and lateral spine with spinules on the anterior margin; coxa of swimming leg with curved spine, which is directed upwards and outwards; ischium, merus and carpus of swimming leg with row of small spines on the anterior margin; a spine at the postero-distal angle of merus, and two smaller spines on the distal margin next to the articulation with the carpus (modified from Rathbun 1930).
