E t y m o l o g y: Named after the Chinese city Honggu, located in the Qinghai province, where three specimens were found.

D e s c r i p t i o n: Male, hind wings absent, 1,9 mm. Reddish-brown, moderately shining ( fig. 1 ). Eyes small but convex with only a small number of ommatidia. Pronotum nearly broad than long, 1,1 times broader than long, broadest in the middle, strongly punctate, margin with one tooth in the middle, anterior callosities prominent, with a welldefined tooth oriented backwards, surface of the callosities visible from above. Margin of pronotum rounded, with rectangular posterior angels. 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, 3 nearly two times longer than broad, 1 and 2 long as broad, 2 moniliform, 1 asymmetric, 9 and 10 slightly transverse, 11 longer and oval. Parameres as fig. 2.

C o m m e n t Cryptophagus hongguanus nov.sp. resembles to Cryptophagus puetzi ESSER, 2017 from Sichuan and Cryptophagus schuelkei ESSER, 2017 from Yunnan ( ESSER, 2017b). Both are wingless with small eyes, stout legs and antennae and elongate elytra. For distinguish them from C. hongguanus the examination of the male genitalia is useful. So far known the three species are also distinguished by their distribution in separated mountain ranges.

Cryptophagus hongguanus nov.sp. resembles also to Micrambe qinghaiensis nov.sp. ( fig. 3 ) from the same locality in general shape. But the latter is well distinguished by the margin of the pronotum with a few small teeth.
