Trissexodontidae is a family of air-breathing land snails, terrestrial pulmonate gastropod mollusks in the superfamily Helicoidea (according to the taxonomy of the Gastropoda by Bouchet & Rocroi, 2005).

Contents

This family has no subfamilies. [2] The family Trissexodontidae was separated out from the families Hygromiidae and Helicodontidae, [2] and some authors still classify these species within those families.

Distribution

The distribution of Trissexodontidae includes the Iberian peninsula, northwest Africa, [4] Azores, [5] Canary Islands, Madeira and Cape Verde. [6]

Genera

Genera within the family Trissexodontidae include:

Description

Shells of species in the family Trissexodontidae are flat and regularly ribbed. The periostracum of the shell surface has no hairs. [4]

A description of the reproductive system was summarized by Prieto et al. (1993). [4]

In this family, the number of haploid chromosomes is known only for the genus Oestophora (n=30). [4]
