Diagnosis. Hasodima ediliacarmenae and H. bartletti are very similar, being distinguished by the shape of the uncus, pseudouncus in male genitalia and the shape of the bursa copulatrix on the females. In H. ediliacarmenae the uncus and pseudouncus are digitiform, while in H. bartletti the subterminal zone of the uncus is enlarged and the pseudouncus is lanceolate. Female genitalia with anterior part of corpus bursae subpyriform in the new species whilst being spherical in H. bartletti .

Description. Adult ( Fig. 1 a). Head brown-green; brown-green, antennae bipectinate. Thorax browngreen; legs similarly colored, tibial spur formula 0-2-4; posterior tibias with hair tuft. Forewings brown-green; antemedial and postmedial lines fine, dark brown-green and close to inner margin of the forewings, antemedial line proximally bordered by a whitish band reaching the basal edge of the wing; ground colour of terminal area lighter than the rest of the wing terminal dots brown; discal dot small, dark brown-green; postmedial line oblique; basal area with dark brown bar perpendicular to the body axis; underside of wings lighter brown-green, with discal dot and diffuse bands. Hindwings ochre, the terminal area dark brown; discal dot and postmedial line barely perceptible; underside of hindwing ochre; postmedial line and discal dot less apparent; terminal area dark brown. Abdomen conlorous to the wings, with dorsal tufts of scales between the third and seventh abdominal segment. Female. Similar to the male, with filiform antennae, posterior tibias without hair tuft.

Male genitalia ( Fig. 2 a–b). Uncus digitiform, apically rounded; pseudouncus digitiform; socii present, with setae; apical cleavage of valves subequal to the width of the valvula; costal margin of valva strongly sclerotized, subapically with digitiform projection; one cuspidiform projection in the center with numerous hairs; gnathos “V” shaped apically widened dentate and tapering tip; juxta subrectangular with two lateral processes in the form of a hook, 1/3 length of uncus; furca acicular, 4 times larger than lateral processes; region of the sacculus hollow; saccus subquadrangular; aedeagus straight, at ductus ejaculatorius constricted; vesica with a group of long and fine spines.

Female genitalia ( Fig. 2 c). Corpus bursae subpyriform, ductus bursae sclerotized with longitudinal furrows; signum large, peduncle and ensiform, five times smaller than the corpus bursae; peduncle the half of the ensiform body of signum; anterior apophyses 1/3 of the posterior apophyses; ductus seminalis arising from intersection between the corpus bursae and the ductus bursae; antrum quadrangular with sclerotized lateral areas, 16 times smaller than the corpus bursae.

Length of forewing. Measured from the base to the apex. Male: 14–15 mm (n = 6); female: 15 mm (n = 2).

Distribution. This species has only been collected in Fray Jorge National Park, in Coquimbo Region of Chile.

Flight period. Specimens of this species have been collected during the austral fall and spring, during the months of April, May, June and October, respectively.

Etymology. This species is dedicated to Edilia del Carmen, the wife of Luis E. Parra.
