Lachana

[1] It contains species native to alpine areas on high mountains in the south of the Central Asia.

[2] This genus, described by Frederic Moore in 1888, was monotypic for over a century, with L. ladakensis as the only species, and thought to be endemic to Ladakh in the Himalayas of India.

[3] In 1984 Karel Spitzer considered that all of the species except L. ladakensis belonged within the genus Gynaephora in the subgenus Dasyorgyia,[2] a move he had made provisionally in 1981 already.

[4] The subgenus Dasyorgyia had as type species Gynaephora pumila, when this taxon was moved by Tatyana A. Trofimova to Dicallomera pumila in 2008, she was also obliged to move Lachana alpherakii, L. selenophora and L. sincera to Lachana from the subgenus Dasyorgyia.

[3] All of the species are native to alpine regions on high mountain ranges in Central Asia.
