Identification

Cochisea are distinguished from related Ennominae by genitalic characters, particularly male valvae structure and female signum . External wing patterns feature wavy or undulating transverse lines, with some species showing reduced pattern elements. Species-level identification requires dissection and examination of genitalia; wing pattern alone is unreliable for distinguishing closely related species such as C. sinuaria and C. rigidaria.

Distribution

Western North America. Documented from Arizona (type locality), California, and adjacent regions of the southwestern United States and northwestern Mexico. Specific state records include California (C. sonomensis, C. undulata), Arizona (C. rigidaria, C. sinuaria), and New Mexico (C. barnesi).
