A checklist and classification of terrestrial prosobranch snails from Son La, north-western Vietnam

Son La is a province in the north-western Vietnam; the mountain chain running in the north-west - south-east direction has very little known so far diverse terrestrial snail fauna dominated by endemic species. This is the first checklist of the terrestrial prosobranch snails from Son La. It includes 42 species, belonging to 17 genera in five families, of which three species are endemic (Dioryx vanbuensis, Cyclophorus implicatus, and Scabrina vanbuensis). In this study two species are recorded for the first time for Vietnam (Chamalycaeus paviei, Scabrina laciniana) and 32 additional species are added to the species list of the Son La.
