Veracruz Freshwater Crab (Tehuana veracruzana)

The Veracruz Freshwater Crab was described in 1972.

The species inhabited the Los Tuxtlas region of Veracruz, Mexico, a small mountain range of volcanic origin, where it co-occurred together with at least five additional crab species. [1]

This species’ name appears in lists of extinct species, however, I could not find out anything else so far.
