Diagnosis. Eupinivora unicolora is easily distinguished from its congeners by the nearly uniform dark rust forewing. The male genitalia are most similar to those of E. hamartopenis , especially in the apically bifurcate transtilla, densely spined sacculus, and overall shape of the valva, but those of E. unicolora are easily distinguished by a long phallus (ca. 1.5 times the length of the valva) that lacks the characteristic external spines present in all other congeners.

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 7.0–9.0 (mean = 8.1; n = 6) in males, 8.0–9.0 (mean = 8.5; n = 2) in females; forewing ( Fig. 7 ) nearly uniform rust, a narrow, ill-defined, cream blotch in distal portion of discal cell, and diffuse area of cream scales at mid-termen. Fringe cream-orange. Hindwing pale grayish brown. Fringe pale gray mixed with cream. Abdomen: Cream-orange. Male genitalia ( Fig. 13 ) with uncus subrectangular, short; socii broad, pendant, attached basally to tegumen by tiny sclerotized rod, creating the appearance of a small bifurcate uncus; median part of transtilla large, rectangular-rounded, with a pair of tiny teeth at middle; valva subrectangular, sacculus strongly sclerotized, with dense long, spines of variable length; phallus ca. 1.5 times length of valva, paired terminal processes long and evenly curved, lacking patch of spines near junction of aedeagus and phallobase. Female genitalia ( Fig. 17 ) with disc-shaped antevaginal sclerite and two broadly rectanglular lateral posterior lobes; lamellae postvaginalis with a narrow sclerotized band; ductus bursae short, not differentiated from corpus bursae, ductus seminalis lateral, originating before middle of corpus bursae.

Distribution and biology. Eupinivora unicolora is known only from La Ciudad and El Salto in the mountains of Durango, Mexico. At least three of the paratypes were reared from Pinus arizonica var. copperi , and it is suspected that all were.

Etymology. The specific epithet refers to the nearly uniform rust color of the forewing.
