The curious genitalic structures of Tancitares michoacanus (Polydesmida, Rhachodesmidae)

摘要

The unusual male and female structures in Tancitares michoacanus Chamberlin, 1942, inadequately documented in the original description, are redescribed and illustrated from type material. The species is reported from a locality in Colima, Mexico, thesecond known for this species. Pararhachistes Pocock, 1909, is suggested as a possible closely related taxon.
