Comment: this crab cannot be determined with the photograph only. It shows some ressemblance with Micropanope lata (Faxon, 1893), from the eastern Pacific and Micropanope lobifrons A. Milne-Edwards, 1881, a species collected in several stations around Guadeloupe during Karubenthos 2012, between 4-95 m. It is distinct from the later by a front more straight and the anterolateral spines less acute, without reduced indentation behind 3th spine. The deep of collection (630/660 m) is also not in the range of M. lobifrons (4-331 m). Related species in Nanocassiope are also be possible.

Comment(s) on data
Micropanope lata (Faxon, 1893) de la baie de Panama (EP), 156 m ressemble aussi au sp. de Karubenthos II, mieux que M. latifrons.
