REMARKS

This male is the single specimen collected by the Travailleur, thus the holotype. The species was known only by the illustration of this specimen by A. Milne-Edwards (1883), that validated the name (see Guinot 1995; Forest 1996; Forest & Holthuis 1997). A description given by A. Milne-Edwards & Bouvier (1900: 15) included a section on “variations” in which another West African crab (an ovigerous female from “ Soudan ”), taken by the Talisman , proved to be a different species, D. pequegnati Guinot, 1995 (see below). The figures provided by A. Milne-Edwards & Bouvier (1900), including the figure of the complete animal, are not those of the holotype. Guinot (1995: 235 [in key], 236, figs 4A-C, 28a-e) redescribed the species.
