This family has no subfamilies (according to the taxonomy of the Gastropoda by Bouchet & Rocroi, 2005).

Distribution

The distribution of Trochomorphidae includes eastern-Palearctic, India, south-eastern Asia, Australian and Polynesia.^[2]

Anatomy

In this family, the number of haploid chromosomes lies between 26 and 30 (according to the values in this table).^[3]
