Diagnosis. The forewing length is 9.5– 10 mm in males and 12 mm in females. The new species has no remarkable external differences from P. monastyrskii . The male genitalia of the two species are similar, but the valva of P. occidentalis sp. nov. is slightly shorter, the costa is less convex medially, the cucullus is broader, the ventral plate of cucullus is longer, and the distal setose section of the distal saccular process is longer, bean-shaped (whereas in P. monastyrskii that is globular). The female genitalia of P. occidentalis sp. nov. are described under the description of the genus.

Distribution. The new species is known from northeastern India (Nagaland) and northern Thailand (Chiang Mai Province).

Etymology. In Latin, ‘occidentalis’ means ‘western’. The specific epithet refers to the species’ more western distribution than P. monastyrskii .
