This paper reports the systematics of the Clausiliidae species occurring in Son La Province, Vietnam. Specimens of 15 species and subspecies of Clausiliidae from Son La were investigated based on their shell characteristics. The subspecies Garnieria mouhoti nhuongi subsp. nov. was collected in Phu Yen, Muong Do, approximately 200 km NE of the type locality of the nominotypical subspecies Garnieria mouhoti mouhoti. This is the first species of genus Garnieria Bourguignat, 1877 from Vietnam.

The results of investigation demonstrate that the eye of Succinea putris is adapted for vision in daytime under pretty high level of illumination.

The study of reproductive tract of the south-east Asian species Helix pernobilis Férussac, 1821 has shown that the species belongs to the genus Koratia Godwin-Austen 1919. The problem of taxonomic rank of the genus Koratia and its comparison with related taxa (Ariophanta and Hemiplecta) are briefly discussed.

Pisidium nevillianum Theobald, 1876, a common pea clam species that widely ranged from India to Indochina, was recorded in the Indawgyi Lake, Northern Myanmar for the first time. These specimens share the same or very similar 16S rRNA haplotypes as specimens from Nepal (geographic distance of over 1,400 km), which could reveal a high dispersal rate of the species, likely via water birds. Same high dispersal possibilities were observed for many other sphaeriid species.
