Diagnosis. Eupinivora angulicosta is superficially most similar to E. ponderosae but can be distinguished by the greater forewing length–mean of 12.0 mm in E. angulicosta vs. 8.4 mm in E. ponderosae . In addition, forewing maculation is considerably darker in E. angulicosta —rust rather than pale orange. The male genitalia of the two are most easily distinguished by the more strongly angled costa of the valva and the narrower phallobase of E. angulicosta .

Description. Head: Vertex and frons white; scaling on antenna white; labial palpus white medially, pale orange laterally. Thorax: Nota white with pale orange scaling, tegula pale orange; fore- and midleg mostly pale orange brown, hindleg mostly white. Forewing length 12.0 mm (n = 1) in male; forewing ( Fig. 4 ) with basal 0.25 pale orange, slightly lighter along entire dorsum, lower portion (toward dorsum) of discal cell with white longitudinal blotch extending to termen just below apex, upper portion (toward costa) of discal cell rust, darker than basal patch, extending through apex. Fringe concolorous with adjacent forewing maculation. Hindwing pale gray. Fringe concolorous with hindwing. Abdomen: White. Male genitalia ( Fig. 10 ) with uncus short, subrectangular; socii subtriangular, descending; transtilla enlarged mesially with patch of slender tooth-like spines; valva broadest at base, abruptly narrowed to about 0.8 basal width beyond sacculus, costa angled at ca. 135° at 0.3 distance from base to apex, sacculus straight, uniform in width, with weakly serrate free edge; phallus with distal paired processes slender, smooth, phallobase narrow, dense cluster of 15–20 large external spines of variable length just apicad of junction of aedeagus and phallobase. Female unknown.

Distribution and biology. Eupinivora angulicosta is known only from the type locality in Nuevo León, Mexico.

Etymology. The specific epithet refers to the distinctly angled costa of the valva in the male genitalia.
