Acanthopteroctetidae
Davis, 1978
archaic sun moths
Genus Guides
1is a small of primitive containing two and seven described . Commonly known as archaic , they are and often exhibit iridescent coloration. The family has undergone significant taxonomic revision, with molecular evidence now placing it in the superfamily Neopseustoidea rather than as the sole family in Acanthopteroctetoidea. Biological data remain scarce, with larval stages documented for only one species.

Identification
Distinguished from other primitive by the combination of small size, activity, iridescent scaling, and absence of ocelli. Structural features of wing separate them from superficially similar groups. Within the family, Acanthopteroctetes are known from Western North America and South Africa, while Catapterix species occur in the Palearctic (Crimea, France, Kyrgyzstan). Female of both Catapterix species remain unknown.
Habitat
Specific associations are poorly documented. Larvae of Acanthopteroctetes unifascia occur on shrubs in the Ceanothus. The undescribed Peruvian occurs in Andean environments. are and associated with daylight conditions.
Distribution
Western North America (four Acanthopteroctetes : California and adjacent regions); South Africa (Acanthopteroctetes nepticuloides); Crimea and southern France (Catapterix crimaea); Kyrgyzstan (Catapterix tianshanica); Peru (undescribed Andean species); China (undescribed species).
Seasonality
of Acanthopteroctetes unifascia emerge in spring. Larvae overwinter and resume feeding in spring before pupating. Seasonality of other is undocumented.
Host Associations
- Ceanothus - larval Acanthopteroctetes unifascia larvae are leaf-miners on Ceanothus shrubs (Rhamnaceae)
- Ribes - probable larval Single tentative record of Acanthopteroctetes bimaculata from leaf mine on Ribes sp. (Grossulariaceae)
Life Cycle
Known primarily from Acanthopteroctetes unifascia: laid on plant; larvae are leaf-miners forming blotch-shaped mines; larvae overwinter; feeding resumes in spring; occurs in cocoon on ground; emerge in spring. Larval stages of remaining six described and both undescribed species are unknown.
Behavior
are . Larvae are leaf-miners, creating blotch-shaped mines in leaves.
Similar Taxa
- NeopseustidaeClosely related now placed in same superfamily Neopseustoidea based on molecular phylogenetic evidence; previously classified in separate superfamilies
- AenigmatineidaeRelated in proposed superfamily Neopseustoidea; shares molecular phylogenetic affinities
- EriocraniidaeAnother of primitive with leaf-mining larvae; historically confused or compared due to similar and phylogenetic position
- CatapterigidaeJunior synonym; originally described as separate for Catapterix but merged with based on shared specialized structural features including wing
More Details
Taxonomic instability
Classification has shifted substantially: formerly sole in superfamily Acanthopteroctetoidea and infraorder Acanthoctesia; molecular evidence now supports placement in Neopseustoidea with and Aenigmatineidae. Some analyses suggest may render Neopseustidae non-monophyletic.
Data deficiency
Of seven described , complete larval descriptions exist for only one (Acanthopteroctetes unifascia). Female of both Catapterix species are unknown. Two additional species await formal description.
Conservation status
No in this have been evaluated by the IUCN as of September 2022.
