Diagnosis: Pseudalypia crotchii is a highly unusual acontiine and is unlikely to be confused with any other species in the subfamily or in the Noctuidae as a whole. The basic color is black. The costa is white. The outer margin of the hindwing has a pure white fringe. Two basic forms of the species exist. Both forms occur in both sexes. The first form has a wide white stripe in the general position of the postmedial line and a white spot at the apex of the forewing.. The second form lacks these white markings. Forewing length from base to apex in one selected individual 11 mm.

Distribution: (Based only on material in the USNM). The species appears to be restricted to southern California.
