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.
