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.
