Bello leg.; MNCN20.04/03991 • 4 ♂♂; Anatael Cabrera leg.; appears in the 1910 catalogue, so its collection date is earlier; MNCN20.04/3448. 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).
