Acanthopteroctetes unifascia
Davis, 1978
Acanthopteroctetes unifascia is a small in the Acanthopteroctetidae, described by Davis in 1978. It is known from Montana, where are active in July. The has been studied for its anatomical features, which retain ancestral traits while also showing unique specializations in larval trunk and adult structures. These characteristics suggest it represents a transitional form in moth evolution.

Identification
Distinguished from other Acanthopteroctetes by the three large pale yellowish spots on the forewings combined with the coppery-lustered fuscous ground color. The specific epithet 'unifascia' (meaning one-banded) may refer to a pattern element, though the description emphasizes spots rather than a continuous band. The small size (11 mm wingspan) and Montana distribution help narrow identification.
Distribution
Known only from Montana, United States. Specific locality details not provided in available sources.
Seasonality
are on wing in July. Probably (one per year).
Life Cycle
Probably with one per year. Larval unknown.

Evolutionary significance
Studies have shown that A. unifascia retains several ancestral traits while also displaying unique specializations in both larval trunk and structures, suggesting it represents an important transitional form in evolution.
