Diagnosis. Eupinivora ponderosae is superficially most similar to E. angulicosta but the latter has a conspicuously greater forewing length (mean 10.2 mm vs. 8.4 mm) and darker rust maculation. The male genitalia of the two are most easily distinguished by the more conspicuously angled costa of the valve of E. angulicosta .

Description. Head: Vertex and frons white; scaling on antenna white; labial palpus white medially, pale orange laterally. Thorax: Nota white with some pale orange scaling, tegula usually pale orange; fore- and midleg mostly pale orange brown, hindleg mostly white. Forewing length 7.5–9.0 (mean = 8.4; n = 10) in males, 8.5– 9.5 (mean = 9.0; n = 5) in females; forewing ( Fig. 3 ) with basal 0.25 pale orange, slightly paler orange along dorsum from base to ca. 0.9 distance to tornus; a slightly darker orange, subrectangular blotch in upper distal 0.5 of discal cell concolorous with basal patch, remainder of wing white with ill defined, scattered patches of pale orange. Fringe white and cream. Hindwing pale gray. Fringe pale gray. Abdomen: White. Male genitalia ( Fig. 9 ) with uncus short, subtriangular, lobelike; socii subtriangular, descending; transtilla enlarged mesially with dense patch of slender spines, median pair conspicuously longer, with adjacent pairs diminishing in size; valva broadest at base, abruptly narrowed to about 0.8 basal width beyond sacculus, sacculus straight, uniform in width, with non-serrate free edge; terminal processes of phallus modified, one slender, curved, smooth, other a broad crenulate plate, phallus with dense cluster of 15–20 large external spine-like setae of variable length immediately apicad of junction of aedeagus and phallobase. Female genitalia ( Fig. 15 ) with lamella postvaginalis comprised of a broad, semi-sclerotized, shield-shaped plate and a pair of broad, subrectangular lateral posterior lobes narrowly separated mesially, lamella antevaginalis a sclerotized, weakly crenulate band. Ductus and corpus bursae as described for the genus

Distribution and biology. Eupinivora ponderosae ranges throughout much of the montane regions of the western United States from Nevada, Utah, Wyoming, and Colorado, south to Arizona and New Mexico, and east to Texas, at elevations from about 1700 to 2700 m. One specimen from New Mexico was reared from Ponderosa pine ( Pinus ponderosa P. & C. Lawson; Pinaceae ), and all specimens were collected in conifer-dominated habitat. A series of specimens from New Mexico was collected by J. Powell (EME) in traps baited with a synthetic pheromone for the bud worm Choristoneura lambertiana (Busck, 1915) (Archipini) —90% 92:8E:Z11-14AC, 10% 90:10E:Z11OH—which is consistent with that of other Cochylina. In pheromones of Archipini there is a prevalence of cis-isomers, whereas in those of Cochylina there is a prevalence of trans-isomers (Safonkin 2007). Adult captures are from June and July with a single record from late May (Texas).

Etymology. The specific epithet refers to the putative larval host and dominant tree in its habitat—ponderosa pine ( Pinus ponderosa ).
