Diagnosis. Eupinivora rufofascia is easily distinguished from its congeners by the forewing pattern, which features ill-defined and interrupted rust fasciae and the absence of a pale streak or patch in the discal cell. The male genitalia are most similar to those of E. unicolora , especially in the short pair of mesial teeth of the transtilla, the densely spined sacculus, and long phallus. However, the male genitalia of E. rufofascia are easily distinguished by the characteristic dense cluster of external spines from the phallus which are absent in E. unicolora .

Description. Head: Vertex and frons pale cream; scaling on antenna cream; labial palpus cream medially, pale orange laterally. Thorax: Nota pale cream-orange, paler at prothoracic collar, tegula rust-orange; legs mostly pale orange brown. Forewing length 9.0–10.5 (mean = 9.7; n = 3) in males, 10.5 (n = 1) in females; forewing ( Fig. 8 ) ground color pale rust, with indistinct, dark rust, basal, median, and subterminal fascia; termen irregularly marked with dark rust; no trace of cream blotch in discal cell. Fringe concolorous with markings. Hindwing grayish brown. Fringe gray mixed with cream. Abdomen: Cream-orange. Male genitalia ( Fig. 14 ) with uncus subrectangular, short; socii broadly rounded; median part of transtilla large, subrectangular, weakly attenuate distally, with a pair of tiny teeth distally; valva subrectangular, sacculus with dense patch of long spines; phallus long, ca. 1.4 times length of valva, paired terminal processes long and evenly curved, with cluster of long spines near junction of aedeagus and phallobase. Female genitalia ( Fig. 18 ) with broad, semicircular antevaginal sclerite, sterigma with two broad subrectangular lateral lobes; ductus bursae short, not differentiated from corpus bursae.

Distribution and biology. Eupinivora rufofascia is known only from La Ciudad and El Salto in the mountains of Durango, Mexico. The holotype was reared from Pinus arizonica var. copperi , and it is suspected that the paratypes were, as well.

Etymology. The specific epithet refers to the nearly rust colored fascia of the forewing.
