Distribution Chile (Conception, Nuble, Colchagua, Santiago, Valparaiso) in the central lowlands and lower western slpes of the Andes (Nielsen & Robinson, 1983).
Systematics Revised by Nielsen & Robinson (1983). Single species with distinctive and unique wing pattern and prominent projecting medial lobe on the caudal margin of the vinculum in the male genitalia. This species also has a scent gland at the base of the forewing. A corresponding basal forewing gland is rare in the Hepialidae, being also present in Phassodes vitensis (Fiji), at least some Palpifer (eastern Asia), and a new undescribed genus from Peru. Whether these similarities are indicative of a close relationship remains to be assessed. The hind tibia have long androconia (Nielsen & Robinson, 1983). This feature is also found in a variety of other genera, but only Phassus in Latin America, and Sthenopis in North America.
