Figs 18 , 37 , 55 , 80

Description. Head: Antenna bipectinate in male, adpressed, unknown in female. Frons brown. Labial palpus brown, ventral surface whitish. Vertex greenish. Thorax: Dorsal side of thorax green, concolorous with wings, ventral side white. Hind tibia with two pairs of spurs in male. Forewing length: 317 mm. Wings green. Forewing: costa yellow; antemedial and postmedial lines almost straight from costa to inner margin. Hind wing with postmedial line straight from costa to M3, then bending inwards and sinuous to inner margin. Fringes of both wings bluish green. Abdomen: Eighth tergite in male with distal half narrow and posterior margin almost flat. Eighth sternite bearing two large lateral processes, basal half straight, distal half slightly curved, unevenly bifid at tip with the diverging point at about distal one-fifth. Male genitalia: Uncus rod-like, slightly tapering. Socii relatively narrow and tapering. Gnathos lacking basal and lateral protrusion, with median process rod-like. Valva broad, blunt terminally; costal extension arising from less than distal one-fourth, slightly recurved. Ventral margin of valva with a small excavation medially. Juxta large, with two small lateral processes protruding posteriorly. Saccus rounded. Aedeagus spinulose posteriorly, both lateral lobe and cornutus blunt and slightly sclerotized. Female genitalia: Unknown.

Material examined. Holotype 3, CHINA: Yunnan ( IZCAS): Xishuangbanna, Xiaomengyang, 850 m, 3.VII.1957, coll. Wang Shuyong (Slide No. 1246).

Diagnosis. The differences from the previous species are listed under P. subquadraria . In the male genitalia, the recurved costal extension is similar to that of P. rana Holloway, 1996 (Borneo) and P. tridens Holloway, 1996 (Borneo) , but it is located more distally than in the other two species. The lateral processes on the eighth sternite are slender and unevenly forked in P. sinuspinae , but short, broad and bearing three to four spines in P. rana and P. tridens .

Distribution. China (Yunnan).

Etymology. The specific name is from the Latin prefix sinu- and the Latin word spina, referring to the curved costal extension.
