Orybina puerensis Qi & Li , sp. nov.

( Figs 5 , 16 )

Type material. Holotype ♂, CHINA: Taiyanghe Nature Reserve (22.60°N, 101.11°E), Pu'er City , Yunnan Province, 1626 m, 9-VII-2013, leg. Shurong Liu, Yuqi Wang and Kaijian Teng, genitalia slide No. QMJ15185 . Paratype: 1 ♂, same data as holotype, genitalia slide No. QMJ15186 .

Diagnosis. This species is similar to O. flaviplaga and O. kobesi superficially by having a yellow costal spot. It can be distinguished from them by the forewing having a triangular black spot on the inner side of the yellow costal spot and the obliquely straight antemedial line; in the male genitalia by the uncus concave medially at apex and the tegumen with thorn-shaped process from each side ventrally ( Fig. 16 ). In O. flaviplaga and O. kobesi , the forewing lacks the black spot on the inner side of yellow costal spot, the antemedial line is incurved in O. flaviplaga posteriorly and sinuate in O. kobesi ; in the male genitalia, the uncus is rounded at apex in O. flaviplaga and pointed in O. kobesi , and the tegumen lacks the ventral processes in both O. flaviplaga and O. kobesi .

Description. Adult ( Fig. 5 ): Wingspan 38.0–41.0 mm. Frons covered with yellowish-white and pale pink scales. Labial palpus pink on outer side, brown on inner side, first segment white on ventral half, about 2/3 length of second segment, third segment same length as second. Maxillary palpus pink, tiny. Antenna with scape dilated, covered with pink scales; flagellum brown, with fine cilia ventrally. Patagium and tegula yellowish-pink. Forewing purplish-brown except saffron from below costa to dorsum before antemedial line, along dorsum below vein A and between postmedial line and termen below vein CuA1; antemedial line black, from basal 1/6 of costa obliquely straight outward to basal 2/5 of dorsum; postmedial line fuscous mixed with reddish-brown scales, serrated, from distal 1/4 of costa obliquely inward to 1/2 of dorsum; heart-shaped yellow spot on inner side of postmedial line anteriorly, bounded by a reddish-brown line except along costa, black triangular spot on outer side of reddishbrown line; distal part of veins R4 to CuA2 covered with black scales, basal half of CuA1 and CuA2 mixed with reddish-brown scales, vein A covered with black scales from antemedial line to tornus; cilia fuscous. Hindwing saffron, costa and dorsum areas pale saffron; postmedial line reddish-brown, invisible posteriorly; vein M2 to CuA2 covered with fuscous and reddish-brown scales distally; cilia fuscous at middle, pale reddish-brown near tornus. Foreleg with femur and tibia purple red, tibia with a tuft of hairs on inner side, tarsus yellowish-white; mid- and hindlegs with femora and tibiae purple, tarsi yellowish-white.

Male genitalia ( Fig. 16 ). Uncus tounge-shaped, concave at middle of apex. Gnathos lateral arms wellsclerotized, approximated at middle, with a small seed-shaped projection between two arms, distal half of lateral arms hooked. Tegumen enlarged anteriorly, with a thorn-shaped lateral process at each side ventrally. Valva broadened towards rounded apex, distal 1/3 with longitudinal ridges; clasper ridge-shaped, at distal 1/3 near ventral margin of valva. Vinculum triangularly produced anteromedially. Juxta oval, concave in V shape on posterior margin. Phallus cylindrical, slightly curved at middle, distal 1/6 sclerotized.

Female genitalia. Unknown.

Distribution. China (Yunnan).

Etymology. The specific name is derived from Pu’er (Yunnan Province, China), where the type locality, Taiyanghe Nature Reserves is located.
