Description. Female. Head: Pale brownish yellow. Thorax ( Fig. 11 ): Forewing length 13 mm; forewing costa sinuate, apex pointed, termen sinuate, dorsum parallel to costa. Markings and colouring in forewing and hindwing the same as described for male. Abdomen: Genitalia ( Fig. 61 ) with papillae anales narrowed posteriorly, distal end truncate; apophyses slender, apophyses posteriores ca. one-half as long as apophyses anteriores, apophyses posterior connected ventrally by a band; sterigma broadly triangular, lamella postvaginalis membranous, lamella antevaginalis membranous, bordered by a sclerotized band; ostium small, irregular, U-shaped, colliculum short, with sclerotized lateral bands, rounded distally; ductus bursae long and slender, cestum as long as ductus bursae except for a small area near colliculum; corpus bursae ovoid, signum a large curved horn, capitulum short.

Distribution. India, Bhutan.

Remarks. This species is newly recorded for Bhutan. Species of Chirapsina have the same venation as those of Archips . Chirapsina is distinguished from Archips by the characteristic long, slender plate of the gnathos and the typical uncus in the male genitalia ( Razowski 2009). The genitalia of the specimen examined are similar to those of C. expleta figured in Clarke (1958: 40). At the same location, a male and a female with markings and colouration similar to C. expleta were collected, and the female genitalia are different from other known Archipini . Hence, it is almost certainly the female of C. expleta and is described and illustrated here for the first time.
