Diagnosis. On wing pattern, P. falcipennis is similar to P. spurcataria and P. crypta , but can be distinguished by the following features: the area between median and postmedial lines is narrower, and this area on both fore- and hindwings is paler than in those two species. The male genitalia are distinctive in having a truncate valva tip and a triangular process on the costa; the aedeagus is characterized by having a sclerotized band on the manica, which bears two triangular processes, and by lacking a spinose bundle on the vesica, as in P. breviprotrusa , P. bluethgeni and P. boarmiata . In the female genitalia, the coiled ductus bursae is very characteristic. The female cannot be distinguished externally from P. rufolinearia .

Distribution. China (Shaanxi, Gansu, Zhejiang, Hubei, Hunan, Fujian, Guangxi, Sichuan, Yunnan), Nepal.

Remarks. Yazaki (1994) described P. falcipennis from Nepal, illustrating the male and female genitalia. Examination of a long series of IZCAS specimens from Gansu, Hubei, Fujian and Yunnan provinces shows that they have same genitalia as P. falcipennis . The holotype of P. rufolinearia is a female from Moupin, Sichuan Province, which is not far from the localities mentioned above, and has same wing as the materials in IZCAS. It seems probable that P. falcipennis should be a junior synonym of P. rufolinearia , but this cannot be confirmed until the genitalia of the holotype of P. rufolinearia are available for examination.
