Lachana selenophora is a species of moth of the subfamily Lymantriinae. It is found in alpine habitats on the high mountains (from 1,000 to 3,600 meters) in Central Asia (Tian-Shan, Pamiro-Alai and Hindu Kush). Description The wingspan is 24–28 mm. The forewings are contrasting pale grey with dark brown bands. The basal area is grey, covered with dark brown scales restricted by a dense dark brown band. The hindwings are widely triangular, dark brown with a wide, dark marginal band. It is a very variable species. Females are wingless and do not leave the cocoon. Infraspecific variability Grigory Grum-Grshimailo distinguishes some geographic variability in wing colour, finding those specimens from the south in the Hindu Kush lighter and somewhat more reddish yellow, with those halfway at Kyzylart Pass intermediate between the two, than the type specimen and specimens from the northern Alay Mountains. Similar species Otto Staudinger, in his original description of the species, found the two males he had access to most similar in wing colour to females of the species Gynaephora selenitica, but smaller. He also compares it to Dicallomera pumila. It is extremely similar to D. pumila, according to Igor Vasilii Kozhanchikov. Taxonomy This species was first described in 1887 by Staudinger under the name Dasychira selenophora based on two adult male specimens sent from a city in what is now southeastern Uzbekistan. He uses the construction Dasychira (Dasyorgyia) selenophora -at present this notation specifically means he classifies it in subgenus Dasyorgyia, but this convention had not yet universally been adopted and in this case he states that he considers it provisionally in the genus Dasychira, but should ever females with stunted wings be found, he would consider it better placed in a new genus, Dasyorgyia, along with the species Dasychira pumila he had previously described from Kazakhstan in 1881. These were grown from caterpillars, and the females had emerged with curiously deformed wings, which led Staudinger to question if the animals had been raised correctly, or if was the natural form. In this 1881 description Staudinger concluded by coining Dasyorgyia as an alternative genus name, should D. pumila require classifying in an independent genus. Grum-Grshimailo, in his work on the moths and butterflies of the Pamir region, describes finding this species a number of times during his four expeditions to this region in the late 1880s. He also uses the name Dasychira (Dasyorgyia) selenophora, although he,
