Diagnosis. In the male genitalia, P. subquadraria, P. forceps Holloway, 1996 (Peninsular Malaysia, Borneo, Sulawesi, Philippines), and P. sinuspinae sp. nov. have tapering socii, which are different from the very broad socii in the previous species. The costal extension is excurved in the holotype of P. subquadraria (almost straight in Inoue, 1982: pl. 316, fig. 2), recurved in P. sinuspinae, also excurved in P. forceps but is more acute and longer and extends further and beyond the apex of the valva. In the female genitalia, the lamella antevaginalis bears two lateral pointed processes, and the posterior margin between two processes is rounded. The lamella postvaginalis is appeared as a pair of serrated sclerites. The ductus bursae is very short. The corpus bursae is large, and expanding abruptly in the anterior two thirds. The bicornute signum is present.
Distribution. China (Henan, Zhejiang, Hunan, Fujian, Taiwan, Guangdong, Guangxi), Japan.
Biology. From one specimen, it is known that one of the food plants is Cinnamomum camphora (Lauraceae).
Remarks. Although the lateral processes on the male eighth sternite are bifid, the diverging point is different among P. subquadraria, P. forceps and P. sinuspinae. It is located at about distal one-third in the type of P. subquadraria, about distal one-fourth in P. forceps, and about distal one-fifth in P. sinuspinae. Many specimens in IZCAS have identical male genitalia to the holotype of P. subquadraria, but the branches of the lateral processes on the eighth sternite are shorter, with the diverging point located at about one-fifth to one-fourth. However, the two forks are of similar length though unevenly. In figure 79 (no label information for the specimen), the diverging point is more basally. The bifid lateral processes of the eighth sternite are variable.
