Redescription of Plesiochactas mitchelli

Little is known about the rare, Central American genus Plesiochactas (Euscorpiidae). Only two species have been described from a handful specimens. Kaleb Zarate-Galvez and Oscar Francke have now redescribed P. mitchelli from an adult female found in Mexico (close to the border of Guatemala where the only other known specimen was collected).

Abstract:
Plesiochactas mitchelli Soleglad 1976 was originally described from a juvenile female collected in ‘‘Guatemala’’ before 1902. The species is redescribed on the basis of an adult female from a specific locality in the state of Chiapas; it is the first record of this species from Mexico.
