Abstract. The new genus and species Uncitruncata leuschneri is described from Cal-
ifornia and Oregon. Habitus photographs of the male and female, and line drawings of
the wing venation and the male and female genitalia are included.
Key Words: moth, phycitine, California, Oregon

be related to phycitine genera treated in fas- convex; under surface of wing of male
