Uroptychus ?spiniger - Guadeloupe (first record?), Karubenthos II 2015, pre-det from photo K. Baba, August 2015 [Examination of the specimen is required to clarify its systematic status], st. CP4539, 12 June 2015, 16°39.35'N, 61°31.86'W, 338-339 m, MNHN-IU-2013-18897.
Comment: According to K. Baba (pers. com., August 2015) the best candidate for this speciment that has lost its chelipeds is U. spiniger, especially in the spinations of the carapace lateral margin and of pereopods 2-4. Examination of the specimen is however needed to verify its taxonomic status.

Comment(s) on data
K. Baba, comment by mail August 2015 - The photo specimen looks like Uroptychus spiniger Benedict, 1902 from off Habana, especially in the spinations of the carapace lateral margin and of pereopods 2-4 (meri with a few dorsal spines and the propodi with flexor spines restricted to the distal portion) and in having long antennal scale. The rostrum is longer in the holotype, however. I have some illustrations of U. spiniger, which are attached here for you.
The meral spinations of pereopods 2-4 displayed by this specimen are also similar to those of U. minutus and U. marissae but the propodal spination of pereopods 2-4 looks different (see the attached file "2015-Baba&Wicksten) and the antennal scale is longer in your specimen.
Examination of the specimen is required to clarify its systematic status.
