Munidopsis barbarae - Guadeloupe (first record), Karubenthos II 2015, field det. J. Poupin [Based on Boone (1927) and Mayo (1974: 363, relationship between M. squamosa and M. barbarae] - morph 1 (rostrum sides not smooth) st. DW4573, 17 June 2015, 16°19.9'N, 60°54.6'W, 413-389 m, MNHN-IU-2013-18962, 18964.
Comment: Munidopsis barbarae is figured in Boone (1927, fig. 13). It resembles M. squamosa but with spines on carapace instead of tubercles for M. squamosa (Mayo, 1974: 363). The species is also remarkable by a corneous spine on dorsal cornea, reported as ‘squamous protuberance’ (Melo, 1999) or ‘spine’ (Chace, 1942). According to D. L. Felder (pers. com., September 2016) this ‘morph 1’ cannot be M. barbarae. Perhaps a new species.

Comment(s) on data
There are 2 distinct forms in the sample from Guadeloupe, one with lateral sides of rostrum not smooth, the other with lateral side of rostrum smooth (ressembling more to M. barbarae as illustrated in Boone (1927); both forms have a corneous spine on cornea indicated by Boone (1927) as 'eyestalk dorsal portion with a calcareous band which is produced at its inner dorsal angle into a large oblique process which is armed with three spinules on its anterior lateral margin and which projects upon the cornea for its entire length'
