Aseptis
McDunnough, 1937
Aseptis is a of erected by James Halliday McDunnough in 1937. The genus contains approximately 15 recognized , with some authors grouping them into informal based on morphological similarities. Species are primarily distributed in western North America. The genus has undergone taxonomic revision, with several former species now excluded.

Identification
Aseptis are distinguished from related by a combination of pattern elements and genitalic structures. Members of the A. fumeola species group show characteristic fuscous or smoky coloration with reduced pattern contrast. The A. lichena species group exhibits lichen-mimicking gray-green coloration. Accurate identification to species level generally requires examination of male or .

Distribution
Western North America, primarily the United States and Canada west of the Rocky Mountains, with some extending into adjacent regions of Mexico. The shows highest in California and the Pacific Northwest.
Seasonality
periods vary by and elevation, with most activity occurring from late winter through early autumn. Lower elevation species often show bimodal flight patterns corresponding to spring and late summer .

Taxonomic history
The was established to accommodate previously placed in other genera, particularly those with reduced pattern elements. Mustelin (2000, 2006) contributed significantly to modern through revisionary work.
Species groups
Informal groupings (fumeola group, lichena group) reflect morphological convergence and shared ecological preferences rather than confirmed phylogenetic relationships.
