Diagnosis. Eupinivora albolineana is superficially most similar to E. angulicosta ; both are somewhat larger than their congeners. The male genitalia of the two are easily distinguished by the more strongly angled costa of the valva in E. angulicosta , and the shorter sacculus and highly modified median portion of the transtilla (bearing a dense cluster of spines) in E. albolineana .

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 10.0– 10.5 mm (n = 4) in male; forewing ( Fig. 5 ) with basal 0.25 pale rust-orange, slightly paler orange along entire dorsum, lower portion (toward dorsum) of discal cell with white longitudinal blotch, abruptly narrowed and angled to subapical portion of termen as a fine white line; upper portion (toward costa) of discal cell pale rust-orange, concolorous with basal patch, extending through forewing apex. Fringe concolorous with adjacent forewing maculation. Hindwing pale gray. Fringe concolorous with hindwing. Abdomen: Pale gray. Male genitalia ( Fig. 11 ) with uncus short, subrectangular; socii subtriangular, descending; transtilla enlarged mesially with large, dense, complicated patch of long spines and shorter serrations, broadened antero-basally in form of rounded-rectangular shield; valva broadest at base, narrowed to about 0.8 basal width beyond sacculus, costa angled at ca. 0.15 distance from base to apex, sacculus straight, short, uniform in width, with free dorsal edge; phallus with distal paired processes slender, smooth, phallobase narrow, with dense cluster of 15–20 large external spines of variable length just apicad of junction of aedeagus and phallobase. Female unknown.

Paratypes (33). MEXICO: Durango: La Ciudad, Pueblo Nuevo, Nov 1983, r.f. Pinus cooperi, M. E. Perez & R. Miranda (USNM).

Distribution and biology. Eupinivora albolineana is known only from El Salto and La Ciudad in the mountains of Durango, Mexico. Label data on the paratypes indicate that they were reared from Pinus arizonica var cooperi .

Etymology. The specific epithet refers to white linear patch of the forewing.
