Paratypes: 1♀ with the same than the holotype [cES]; 1♀: " China, Qinghai Prov. [CH11-08a], Daban Shan, 60 km NW Honggu, 36°49’10.7’’N, 102°31’22.8’’E, 2366-2400 m, mixed forest (Betula, Populus, Picea) dead wood, litter sifted, 11.VII.2011, leg. M. Schülke " [MFNB].

E t y m o l o g y: Named after the Chinese Qinghai province, where all specimens were found.

D e s c r i p t i o n: Male, hind wings absent, 1,7 mm. Reddish-brown, shining (fig. 3). Eyes small but convex with only a small number of ommatidia. Pronotum 1,3 times broader than long, broadest nearly in the middle, margin straight between middle and anterior angles (callosities) and between middle and posterior angles, strictly narrowed, strongly and moderately dense punctate, margin with a few teeth (8-9), teeth in middle more prominent, anterior callosities moderately developed, without tooth. Elytra elongate, nearly oviform, with long and decumbent hairs, no humeral callus developed, strongly punctate in the anterior part, less strong punctate in the posterior part, puncture on elytra more sparse than on pronotum. Legs more stout, tarsi five-segmented, posterior tarsi four-segmented (only in male), anterior tarsomeres 1-4 moderately widened (only in male). Antennae quite stout, club well developed, segments 4-8 more (5-8) or less (4) moniliform, 1-3 longer than broad, 1 asymmetric, 9 and 10 slightly transverse, 11 longer and asymmetric.

C o m m e n t Micrambe qinghaiensis nov.sp. is a very small species without hind wings. It resembles to Micrambe alatauensis LYUBARSKY, 2000 from Middle Asia by lacking membranous wings and humeral callus. Micrambe alatauensis is also small species (1,7-1,8 mm).

Micrambe qinghaiensis nov.sp. resembles also to Cryptophagus hongguanus nov.sp. (fig. 3) from the same locality. But the latter is well distinguished by the margin of the pronotum with only one tooth.
