They are: Thylactus dentipennis, Blepephaeus nigrostigma , and Sternohammus yunnana . The genus Sternohammus Breuning is recorded for the first time from China. All the type specimens are deposited in Insect Collection, Southwest Agricultural University. 1 Thylactus dentipennis sp nov (Figs 1-4) Body small in size, blackish brown; antennae as long as body, light yellow, except blackish brown on scape and the apex of 3 to 8 segments: head and prothorax densely covered with blackish brown pubescence and mixed with light yellow as follows: a Y shaped in middle of frons, a transverse line between antennal tubercles, and a narrow vitta in middle of pronotal disc; elytra entirely clothed with thick streaks of pale yellow pubescence, partly blackish brown, subregularly punctured between streaks, emarginated and fringed apically. Male genitalia (Figs 2-4): median lobe with median struts strongly curved, the former being longer than the latter, and distinctly longer than tegmen; the ventral margin of median orifice rounded; tegmen without roof and basal piece; lateral lobes short, densely furnished with long soft setae apically; ringed parts hemmed, converging. Internal sac slender; ejaculatory duct single. Length: 16 5 mm; breadth: 4 5 mm.
