Uroptychus rugosus (A. Milne-Edwards, 1880)

Only one ovigerous female of Uroptychus rugosus was measured from the Yucatan from 237 m depth, which is consistent with its previously recorded locations and within the published depth range of the species (Milne- Edwards 1880; Chace 1942; Baba et al. 2008). The CW was 5.3 mm; the number of eggs and sizes of eggs were not recorded.
