Comment(s) on data
Based on the eroded/not much eroded aspect of carapace, it seems that both O. antillensis/O. tuberosa are present in Guadeloupe, and that some lots have been confused, i.e. MNHN-IU-2013-4545, det. Besse, mars 2013, GN14, JL333, as O. tuberosa, has an eroded carapace and is probably O. antillensis.
