Holotype : CHINA : ♀ , Tibet Autonomous Region , Cuona county [ DḚĦ] , Lexiang [ ÐÞ ], Lecun [ ÐḤ ], Simuzhajingqu [ Ạ+KṞŻ ], N 27.82º , E 91.73º , 2793 m , 1-VI-2016 [night], leg. Hong-Bin Liang. Paratypes : CHINA : 3♀♀ , same data as holotype (IZ-CAS) . Measurements. BL: 6.7‒6.9 mm , PEL: 5.2‒5.3 mm , PW: 3.0‒ 3.1 mm , EW: 3.6‒3.7 mm , ED: 0.63‒0.68 mm . Description. [Based on female] Head black ( Fig. 2A ). Punctuation on head sparse, thin and shallow, area between punctures glossy. Middle of frons with fine punctures; middle of vertex glabrous, with short longitudinal groove. Antenna with articles 1–6 slender, blackish brown to dark; articles 7–10 black, broader than long, apex truncate and circled with pale pubescence ( Fig. 2C ). Pronotum black and slightly convex, with lateral margins slightly sinuate. Surface of pronotum smooth, with punctures of different forms but well delimited, larger and denser than those on head, distance between punctures larger than diameter. Antebasal puncture row impressed, with punctures in middle portion lager than those in lateral portion. Pronotal hypomeron and mesepisternum smooth and impunctate ( Fig. 2A ). Elytra brownish red. Punctures on surface similar to those on pronotum but slightly thinner in apical portion. Each elytron with basal stria row connected with punctate sutural stria, where punctures as coarse as those of pronotal antebasal row ( Fig. 2A ). Legs black with tarsi blackish brown ( Fig. 2D ). Profemur spindly shaped and slightly sinuate on inner side and thinner in apical 1/5 ( Fig. 2D ). Abdomen black. Tergites with fine and moderately dense punctures and dense micropunctures. Sternites with relatively dense and fine punctures and dense micropunctures ( Fig. 2B ). Distribution . China : Xizang . Comments. Scaphidium russipenne sp. nov. can be distinguished from the other related species by the elytra of unifying brownish red colour. Etymology. The specific epithet is from the combination of the Latin words russa (brownish red) and penne (winged), which refers to the elytral colouration.
