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 The native distribution of Trigonochlamydidae includes Caucasus,"Family summary for Trigonochlamydidae". AnimalBase, last modified 26 August 2005, accessed 1 September 2010. Iran and Turkey.
Taxonomy Previously, Trigonochlamydidae was placed in the superfamily Trigonochlamydoidea Hesse, 1882, in the subinfraorder Sigmurethra. This was the only family within that superfamily.Sistemica (Spanish list of genera), cited 7 October 2008.
The family Trigonochlamydidae 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, 1926Hesse P. (1926). "Die Nacktschnecken der palearktischen Region". Abhandlungen des Archiv für Molluskenkunde 2(1): 1–152. page 47 and page 54. plates 1–2.
Genera There are nine genera in the family Trigonochlamydidae with a total of 11 species:
Subfamily Trigonochlamydinae
Boreolestes Schileyko & Kijashko, 1999 Boreolestes likharevi Schileyko & Kijashko, 1999 – type species Boreolestes sylvestris Kijashko in Schileyko & Kijashko, 1999 Drilolestes Lindholm, 1925 – with only one species Drilolestes retowskii (O. Boettger, 1884) Hyrcanolestes Simroth, 1901 – with only one species Hyrcanolestes velitaris (Martens, 1880) Khostalestes Suvorov, 2003 – with only one species Khostalestes kochetkovi Suvorov, 2003 Lesticulus Schileyko, 1988 – with only one species Lesticulus nocturnus Schileyko, 1988 Trigonochlamys O. Boettger, 1881 – type genus of the family Trigonochlamydidae, with only one species Trigonochlamys imitatrix O. Boettger, 1881 Troglolestes Ljovushkin & Matiokin, 1965 – with only one species Troglolestes sokolovi Liovushkin & Matiokin, 1965
Subfamily Parmacellillinae Parmacellilla Simroth, 1910 – type genus of the subfamily Parmacellillinae, with only one species Parmacellilla filipowitschi Simroth, 1910Schileyko A. A. (2003). "Treatise on Recent Terrestrial Pulmonate Molluscs. Part 11. Trigonochlamydidae, Papillodermidae, Vitrinidae, Limacidae, Bielziidae, Agriolimacidae, Boettgerillidae, Camaenidae." Ruthenica, Supplement 2(11): 1467–1626, Moscow. page 1467.
Synonym: Pseudomilax O. Boettger, 1881 is a synonym for various genera in Trigonochlamydidae. Selenochlamys O. Boettger, 1883 has been removed from the Trigonochlamydidae to the Oxychilidae based on DNA evidence.
