Distribution
Taxonomy
Previously, Trigonochlamydidae was placed in the superfamily Trigonochlamydoidea Hesse, 1882, in the subinfraorder Sigmurethra. This was the only family within that superfamily.[4]
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, 1926[5]
Genera
There are nine[3] genera in the family Trigonochlamydidae with a total of 11 species:
Subfamily Trigonochlamydinae
- Boreolestes Schileyko & Kijashko, 1999
- Boreolestes likharevi Schileyko & Kijashko, 1999 – type species[6]
- Boreolestes sylvestris Kijashko in Schileyko & Kijashko, 1999[6]
- Drilolestes Lindholm, 1925 – with only one species Drilolestes retowskii (O. Boettger, 1884)[6]
- Hyrcanolestes Simroth, 1901 – with only one species Hyrcanolestes velitaris (Martens, 1880)[6]
- Khostalestes Suvorov, 2003[3] – with only one species Khostalestes kochetkovi Suvorov, 2003[3][6]
- Lesticulus Schileyko, 1988 – with only one species Lesticulus nocturnus Schileyko, 1988[6]
- Trigonochlamys O. Boettger, 1881 – type genus of the family Trigonochlamydidae, with only one species Trigonochlamys imitatrix O. Boettger, 1881[6]
- Troglolestes Ljovushkin & Matiokin, 1965 – with only one species Troglolestes sokolovi Liovushkin & Matiokin, 1965[6]
Subfamily Parmacellillinae
- Parmacellilla Simroth, 1910 – type genus of the subfamily Parmacellillinae, with only one species Parmacellilla filipowitschi Simroth, 1910[7]
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.[8]
