The species, Hydrochus binodosus Motschulsky, is newly recorded from China. Type specimens of the new species are deposited in Institute of Entomology, Zhongshan University. Hydrochus rhytipterus sp.nov. The new species resembles H. annamita Regimbart, but differs from the latter species in the 5th elytral interstice highly raised in posterior 1/3; the basal piece of aedeagus shorter than paramere; paramere slightly shorter than median lobe; paramere strong in basal 2/3 and narrowed in anterior 1/3, and median lobe expanded at about extreme 1/3 and sharp apically (Fig 4). Length 2 4 mm, width 1 mm. Holotype ♂,paratype ♂, Nanyue(Hengshan)Mountain, Hunan Province, Sept. 12, 1941, collected by Pu Zhelong.
