Remarks

This species is very similar to Xanthodius inaequalis inaequalis (Olivier, 1791) ( Figs 87–88 ). The difference is in the larger cheliped fingertips, which in Xantho are pointed, partially crossing when closed ( Fig. 84 G−I), and in Xanthodius are rounded and hollowed on the occlusal surface, meeting when closed ( Fig. 87 ) ( Poore & Ahyong 2023).

Specimens were labelled as “Sin determinar” (undetermined), and assigned to Xanthidae .

For identification, see also Zariquiey Álvarez (1968) and Poore & Ahyong (2023).
