In the present paper a new genus and two new species of Deltocephalinae are described from China. Moreover, the species Albicostella kiushiuensis Vilbaste is tranfered to this new genus as a new combination, which is reported for the first time from China.The type speci mens are deposited in the Entomological Museum, Northwest Science and Technology University of Agriculture and Forestry. Protensus , gen.nov. Head about as wide as pronotum. Vertex slightly longer medially than next to eyes and middle length is about half of the width between eyes. Eyes fairly large, about half distance between eyes. Occelus is next to eye and distance from occelus to eye is about its diameter. Frontoclypeus is narrow, slightly longer than the distance between eyes. Clypellus is parallel sided. Pronotum with its anterior margin protruded roundly and posterior margin slightly concave. Scutellum with sulcus curved and depressed. Forewing with appendix well deve loped, 4 apical cells, inner anteapical cell open basally, outer anteapical cell small——as about two thirds long as the middle anteapical cell. Pygofer with a pair of appendages at both dorsal and ventral posterior margin. Subgential plate long and wide with outer margin curved. Paramere is narrowing distally with apex tapered. Connective V shaped, shaft short and arms well developed. The aedeagus with basal atrium well developed, shaft short and curved ventrad with a well developed dorsal projection in the middle, and paired or single branched processes in the middle or near posterior margin; phallotreme terminal. Type species: Protensus choui ,sp. nov. Distribution: Palearctic Region including China, former USSR and Japan. This new genus is similar to Albicastella Ishihara in general appearance, but can be distinguished from the latter by following characteristics: 1) aedeagal shaft curved ventrally with a well developed dorsal projection in the middle;2) aedeagus with paired or branched processes in the middle or near posterior margin rat
