Type material. Holotype: ♂, CHINA, Yunnan, Malipo, Mt. Laojun , 8.VIII.2014, leg. Yanju Dong.

Diagnosis. This new species is similar to Ornebius formosanus (Shiraki, 1911) , but differs from the latter by the head and pronotum reddish brown; mirror of tegmina large and elliptical; differs in the shape of male genitalia.

Head small and narrow, the eyes located on edge of the head, not touching antennal sockets; antennal scape slightly elongate, about 1.2 time longer than wide; frontal rostrum convex, frontal rostrum about 1.5 times as wide as scapus. Pronotum distinctly extended backward, fan-shaped, anterior margin nearly straight, posterior margin wide rounded. Tegmina well developed and short, reaching to the base of the 4 th abdominal tergite; mirror well developed, length to width ratio is 2: 3. Fore tibiae with an ovoid internal tympanum, without external tympanum. Hind tibiae with 3 pairs of dorsal spurs and middle spurs longest. First tarsus shorter than half of tibia, with small spines on the dorsal surface.

Supra anal plate very short, with weakly rounded posterior margin ( Fig. 12 ). Genitalia ( Fig. 11 ): epiphallus rather short; ventral median lobe relative long, distinctly raising from underside and covering whole ectoparameres and epiphallus; spermatophore sac massive.
