Diagnosis. Forewing length: 6mm . P. langtangi described from Central Nepal is very similar externally to P. ayutthaya occurring in North Thailand , the two species are easily distinguishable by their surprisingly substantial differences in genitalia ( László et al . 2010 ). In Sikkim, P. langtangi occurs sympatrically with P. sikkima sp. nov. and P. sukhothai , but is unmistakable for both of them according to its conspicuously different forewing pattern split into a clear whitish basal and dark-colored apical half of forewing compared to the more variegated and complex wing pattern of the latter species. The detailed diagnoses of male and female genitalia of the related species are provided in detail in their original descriptions ( László et al . 2010 , László et al. 2006 ). Distribution. India ( Sikkim ) China , Nepal .
