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 ) GoogleMaps . Port St. Charles, St. Peter , subtidal, 13°15’51.81”N, 59°38’36.34”W, 1 ♀ CW: 56.6 mm ( BLSZ 245 ) GoogleMaps .

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).
