Comment: Karubenthos specimens are small with carapace length of about 2 cm, at most. They resemble Nibilia antilocapra with photo of a large specimen from Guadeloupe in Desbonne (1867, pl. 7, fig. 23). The frontal spines are more separated at their base and the chelipeds are shorter. These are perhaps morphological variations for juveniles, as often observed within the Majoidea.
