Diagnosis. Eupinivora thaumantias is superficially most similar to E. angulicosta and E. albolineana : it is among the largest species in the genus and has a rust-brown forewing with a distinct whitish longitudinal dash in the discal cell. The male genitalia of E. thaumantias are easily distinguished by the long, straight, narrow sacculus that extends well beyond the margin of the valva, unlike that of any other species in the genus.

Description. Head: Vertex and frons cream, sprinkled with ferruginous; scaling on antenna white; labial palpus pale ferruginous medially, darker laterally. Thorax: Nota white with some pale orange scaling in anterior portion, rust in distal half, tegula pale orange; fore- and midleg mostly pale orange brown, hindleg mostly white. Forewing length 10.0– 10.8 mm (mean = 10.4; n = 2) in males, 10.0–11.0 mm (mean = 10.3; n = 3) in females; forewing ( Fig. 19 ) ground color somewhat glossy cinnamon-rust, slightly paler along dorsum in some specimens, with narrow white longitudinal dash in distal portion of discal cell; cream, narrow-triangular area extending from apex to beyond mid-termen. Fringe whitish, rust at apex. Hindwing pale gray. Fringe pale gray mixed with white. Abdomen: White. Male genitalia ( Fig. 20 ) with uncus short, broad, somewhat flattened apically; socii broad, semicircular, pendant; median part of transtilla short, subrectangular, with several stout spines, median pair longest and broadest; valva short, somewhat parallel-sided, rounded apically, costa weakly angled ca. 0.2 from base, ventral edge gently and evenly rounded, sacculus strongly sclerotized, long, narrow, straight, extending beyond edge of valva with free, blunt termination; phallus broad, expanding subbasally, with a pair of slender terminal processes distally, a cluster of ca. 6 stout spines near junction of aedeagus and phallobase. Female genitalia ( Fig. 21 ) with lamellae antevaginalis bearing rounded sclerite mesially, sterigma a lightly and evenly sclerotized, broadly U-shaped band, with the posterior edge more strongly sclerotized; ductus bursae short, not differentiated from corpus bursae, ductus seminalis lateral, originating before middle of corpus bursae; corpus bursae elongate, anterior half irregularly rounded with small, evenly spaced spines.

Distribution and biology. Eupinivora thaumantias is known only from the type locality in Estado de Mexico, Mexico. Although the early stages are unknown, it is suspected to be pine-feeder.

Etymology. Presumably from Greek mythology—Thaumantias or Thaumantos, the daughter of Thaumas.
