Current state of knowledge on Virilastacus species (Crustacea, Decapoda, Parastacidae)

The genus Virilastacus was created in 1991 to accommodate Parastacus araucanius Faxon, 1914. At present, Virilastacus comprises four burrowing species, three of which were described at the beginning of the XXI century, and biological knowledge about these species is mainly limited to taxonomic and d...
