REMARKS

Henri Milne Edwards (1837) indicated that the species was from the Antilles. His description mentioning at least two colour morphs (yellow with red marks; and almost entirely red) reveals that he has examined several specimens. The material collected by Plée in Martinique, his country of birth, most likely belongs to the type series according to the entry date “1826” of Plée’s material mentioned in the CAA (see also Bauchot et al. 1990: 117; Appendix). The specimen of “14 lignes” (1 ligne = 0.2255 cm), thus measuring 31.5 mm carapace length, cited by H. Milne Edwards (1837: 85) is no longer present in the MNHN collection, and all the MNHN specimens are smaller. The only male in the Plée material was selected as lectotype.
