Portunus sanguinolentus

Portunus sanguinolentus (Herbst, 1783) Fig. 64 Material examined MAURITIUS • 1 ♀ (139.4 ×61.2); May 1885; Pere Antiga leg.; MNCN20.04/03219. Remarks The internal cavity of the specimen is filled with alcohol, indicating that at some point since its collection in 1885, it has been exposed to dry conditions in the old collections of the MNCN. Obviously, the three red spots on the carapace, which make this species unmistakable, have not been preserved after so many years. It also retains several of the old labels tied with strings. For identification, see also Crosnier (1962) and Naderloo (2017).
