Abstract

Megalobulimus helicoides is a new species collected in Sucusuma village, Potosí department, Bolivia (Pulmonata, Acavoidae, Strophocheilidae). The species is mainly characterized by the deep suture, by the triangular open umbilicus, relatively small spire and proportionally narrow aperture. The sculpture of the protoconch and teleoconch, the red peristome and the deciduous periostracum indicate that the new species belong to the “Megalobulimus oblongus complex”, which is uncommon in the Andinian region of South America.
