Emei, Sichuan, the habitat in the type locality of O. bicolora . Diagnosis. The forewing length is 9.0 mm in the female holotype . The female of O. sapa sp. n. differs clearly from the females of the two other species in the species-group by the reduced blackish suffusion of the hindwing represented by a small diffuse patch at the apex. In the female genitalia, the new species is distinguished from O. binghami and O. thomasi by the triangular and smooth lobes of the antevaginal plate (they are rounded and rugose in the congeners), the dorsal sclerotisation of the ductus bursae protruding into the postvaginal area, the broader, anteriorly more heavily sclerotized ductus bursae, the markedly longer postero-lateral sclerotised pocket of the corpus bursae, and the somewhat broader anterior section of the corpus bursae lacking the signum. The male is unknown. Distribution. Northern Vietnam ( Lào Cai Province ). Etymology. The specific epithet is homonymic of the town of Sa Pa (= Chapa or Cha-pa) located near the type locality of the new species. The name is a noun in the nominative singular in apposition.
