description: Polycaena wangjiaqii Huang, sp. n.
(Figs. 14, 42, 51, 60, 67, 75)
Polycaena lama: Sugiyama, 2015: 36, fig. 4 for ♂ genitalia, pl. 3, figs. 1, 15 for ♂ from NW Yunnan, figs. 2, 16 for ♀ from NW Yunnan.
Type material. Holotype (Fig. 14): ♂, CHINA: Yunnan province, Diqing Tibetan Autonomous Prefecture, Zhongdian County (Shangri-La), Pudacuo National Park, Bitahai, 3200 m, 20.VII.2008, J.-Q. Wang (in an expedition organized by Shanghai Normal University for scientific purpose) leg., deposited in SNUC. Paratype: 1♂, same data as holotype (in coll. Z.-H. Zheng).
Male holotype description. Length of forewing: 16.0 mm. Eye hairy. Antennal club with pale patch at base. Both wings same shaped as in P. l am a.
Wing-pattern (Fig. 14). Both wings on upper side with all markings placed as in P. l a m a, but colored in a different way: cell spot and postdiscal spots in spaces 1b-5 of forewing reddish orange, postdiscal spots in spaces 6 and 10 of forewing cream, not white as in P. l ama. Both wings underside exactly as in P. lama.
Male genitalia (Figs. 42, 51, 60, 67, 75). Uncus in dorsal without branches. Fenestrula narrowly present at middle. Valva elongate, without the ventral branch found in P. lama. Ampulla of valva remote from distal tip of harpe, not overlapped by harpe. Harpe of valva elongate, without inner process rising from sacculus. Central plate of valvae with posterior branches longer than basal part, depressed dorsoventrally. Juxta with dorsal part extending both anteriorly and posteriorly in lateral view. Phallus in lateral view sinuate, without a dorsal corner. Coecum penis in dorsal view not expanded laterally.
Description of male paratype. No individual variation found between the paratype and holotype.
Etymology. This new species is named in honor of Mr. Wang Jia-Qi, Shanghai, who collected the type series.
Diagnosis. This new species is similar to P. l am a in external features, but can be distinguished from it by the following combination of male characters: 1) postdiscal spots and cell spot on forewing upper side are reddish orange in color, not white as in P. lama; 2) fenestrula of male genitalia is present at middle; 3) valva has a ventral branch rising from sacculus; 4) harpe has no inner process; 5) harpe is more elongate, well separated from ampulla and has a much longer dorsal margin; 6) ampulla is more pointed at distal end; 7) central plate between valvae has posterior branches depressed dorsoventrally; 8) central plate is well exposed, not concealed by valvae; 9) juxta has both anterior and posterior branches equal in length; 10) juxta has posterior branches more sharply pointed at ends; 11) phallus is longer and more sinuate, and has apical two fifth down-curved in lateral view.
The new species can be distinguished from all other species of the genus as in the key below.
Remarks. It is remarkable that P. wangjiaqii and P. lama have great similarity in external features but have significant differences in male genitalia.
