Helicina pitalensis
The Costa Rican Helicinidae

The Helicinidae of Costa Rica were reviewed during my research in the years 1999-2002 (RICHLING 2004a, b). The results are mainly based on own field work in Costa Rica, the additional study of the extensive collection of land snails in Costa Rica (formerly housed by the Instituto Nacional de Biodiversidad de Costa Rica - INBio - now moved to the Museum of the University of Costa Rica in San Josť-San Pedro) and respective type material. Specimens from various other sources were also included (e. g. historical material collected by BIOLLEY).
