Trigonochlamydidae is a family of air-breathing land slugs, terrestrial gastropod molluscs in the clade Eupulmonata (according to the taxonomy of the Gastropoda by Bouchet & Rocroi, 2005).

Distribution[edit]

The native distribution of Trigonochlamydidae includes Caucasus,[1] Iran and Turkey.[2]

Taxonomy[edit]

Previously, Trigonochlamydidae was placed in the superfamily Trigonochlamydoidea Hesse, 1882, in the subinfraorder Sigmurethra. This was the only family within that superfamily.[3]

The Trigonochlamydidae family is now classified within the limacoid clade, which itself belongs to the clade Stylommatophora, within the clade Eupulmonata (according to the taxonomy of the Gastropoda by Bouchet & Rocroi, 2005).

The following two subfamilies have been recognized in the taxonomy of Bouchet & Rocroi (2005):

  • subfamily Trigonochlamydinae Hesse, 1882 - synonyms: Selenochlamydinae I. M. Likharev & Wiktor, 1980
  • subfamily Parmacellillinae Hesse, 1926[4]

Genera[edit]

There are nine[2] genera in the family Trigonochlamydidae with a total of 11 species:

Subfamily Trigonochlamydinae

Subfamily Parmacellillinae

Synonym:

  • Pseudomilax O. Boettger, 1881 is a synonym for various genera in Trigonochlamydidae.
