Andesiana is a genus representing its own family Andesianidae and superfamily Andesianoidea, the "Andean endemic moths". It contains three species with a wingspan up to 5.4 cm. in female A. similis and 3.5 cm. in males. This far surpasses in size any previously known monotrysian moth. These large Microlepidoptera[1] are restricted to Andean South America, from where they were described originally in 1989 in the family Cossidae by their discoverer Patricia Gentili.
The vein "R2" in the hindwing is two-branched, suggesting that the Andesianidae family is basal to the superfamily Nepticulidae, but the way the wings are coupled suggests it had a later origination within the Monotrysia, where it can be placed based on characters of the female reproductive system. The relationships of Andesiana with representatives of other lepidopteran superfamilies is currently under investigation using DNA sequences [2].
The labial palpi have an elongated second segment, the tibia of the male hindleg has a "hairpencil" contained in a pouch on the femur, and the antennae are "bipectinate" in the male and "filiform" in the female; the proboscis is much reduced.
