Type material. CHINA, Hainan: Holotype ♂, Shuimanxiang (18.88°N, 109.66°E), Chongmentou Town, Wuzhishan City , 630 m, 30.VII.2013, leg. HL Yu & Y Fei, slide No. WYQ16703 . Paratype: Guangxi: 1♂, Jinxiu County, 650 m, 28.IV.2008, leg. H Zhen & L Zhang, slide No. JYY16050 .

Diagnosis. The new species can be distinguished from its congeners by the costal part with an apical spine straightly directed dorsad, the ventral part of the valva with two apical spines, and the aedeagus with a stout spineshaped process arising from the middle.

Description. Adult ( Fig. 16 ). Forewing length 5.6–6.0 mm.

Head yellowish brown. Antenna yellow on ventral surface; scape dark brown, flagellum brown alternated with pale yellow on dorsal surface. Labial palpus yellow; second palpomere with brown scales on outer surface, brown at apex; third palpomere with sparse brown scales.

Thorax and tegula brown. Forewing ground color yellow, with brown scales, with dark brown spot near base of both subcostal vein and dorsum; costal margin dark brown along basal 1/3; discal, discocellular, plical and tornal spots dark brown, discocellular spot largest; terminal dots dark brown, ranging from distal 1/6 of costal margin along termen to tornus; fringe yellow. Hindwing deep brown, except white in costal area under forewing; fringe brown. Fore- and midlegs brown, tarsi yellow at apex of each tarsomere; hindleg yellow, with brown scales on outer surface, yellow at apex of each tarsomere.

Male genitalia (Fig. 42). Uncus clavate, wide at base, narrowed to rounded apex. Gnathos with mesial plate triangular, pointed at apex; basal arms banded, relatively wide. Tegumen rectangular and wider medially; lateral arm slender, slightly narrowed to pointed apex. Valva with basal half sub-rectangular, distal half slightly narrower, divided into two parts from distal 1/4: costal part weakly sclerotized, birdhead-shaped, with an apical spine directed straightly dorsad, forming a right ventroapical angle; ventral part heavily sclerotized, bent inward ventrally, produced to a spine-shaped process lateroapically; ventral plate being a narrow band extending from base to before middle of costal margin, arched to 1/4 width of valva from ventral margin. Saccus broad and short, rounded at apex. Juxta weakly sclerotized, sub-rectangular. Aedeagus slightly shorter than valva, thicker in basal half, thinner in distal half, with a stout spine-shaped process arising from middle; cornutus absent.

Female unknown.

Distribution. China (Guangxi, Hainan).

Etymology. The specific epithet of the new species is derived from the Greek ornis, ornithis (bird) and rhynchos (snout), referring to the bird-beak-like shape of costal part of the valva in the male genitalia.
