Trigonochlamydidae

Selenochlamys ysbryda

The Trigonochlamydidae are a family of terrestrial snails ( gastropod ). There are slugs with a small rudimentary housing in the shell plate. In some species, it stands out even in part from the mantle.

Features

The animals are relatively small and outstretched usually only max. 3 cm long. The shell plate is relatively small, with few exceptions, and usually sits in the middle of the back of the animal. The sole of the foot is divided into three parts. The cabinet is very rudimentary and covered by the mantle shield. In one type the Embryonalgehäuse from the jacket stands out. The nucleus ( Embryonalgehäuse ) is still rolled up in a spiral, then a small plate joins, which is only partially mineralized. The jaws are rudimentary or absent. The radula has 52 to 64 rows of unicuspid teeth; there are up to 56 teeth per transverse row.

Lifestyle and deposits

Because of the radula and anatomy of the pharynx is accepted by the animals that they are carnivores. Only of the type Hyrcanolestus armeniacus Simroth is known that she hunts earthworms. They are found in the Caucasus and the mountains of northern Turkey and northern Iran.

System

The family is still divided by Schileyko (2003) into the subfamilies Trigonochlamydinae and Likharev & Wiktor Selenochlamydinae, 1980. Hausdorf (1998) does, however, before a subdivision in Trigonochlamydinae and Parmacellillinae Hesse, 1926. Only the genera are listed.
