Resumo

A new genus and species of land planarian, Pichidamas piru gen. nov. sp. nov., is described from Pichidamas, province of Osorno in Southern Chile. Pichidamas piru is a sub-cylindrical and slender Geoplaninae characterized by the presence of a creeping sole extending 50% of the body width, a cephalic retractor muscle, five parenchymatic muscle layers, a male atrium with proximal tongue-like fold and distal adenodactyl; and ovovitelline ducts approaching the copulatory apparatus anteroventrally. Details of the organization of the cephalic retractor muscle, the absence of sensory pits, the existence of a parenchymatic muscle layer, located to the inside of the ventral peripheral nervous plexus, and an adenodactyl in the distal portion of the male atrium are unique traits seemingly reflecting an earlier branch of Geoplaninae.
