Amorbia erinae, new species, is described and illustrated from the states of Durango and Chihuahua, Mexico. Superficially, the new species is highly divergent from its congeners, with a forewing pattern that features longitudinal bands of pale orange and cream, typical of tortricids that either feed on pine or occur in pine-dominated montane habitats, e.g., Eupinivora ponderosae Brown (Euliini: Cochylina), Argyrotaenia coconinana Brown & Cramer (Archipini), and Sparganothis bistriata Kearfott (Sparganothini). However, the absence of ocelli and features of the male and female genitalia convincingly place the new species in Amorbia.
