Two new species of Tetracneminae, Encyrtidae, collected from Heilongjiang, Liaoning, and Yunnan, China are described, i.e. Dusmetia latiscapa Xu, sp. nov, and Gyranusoidea yunnanensis Xu, sp. nov. Dusmetia latiscapa Xu, sp. nov differs from Dusmetia cardinalis Hoffer, 1969 in the coloration of the apical forth funicular segment and the fifth‐sixth funicular segments of antennae; (2) length of scape; (3) having undeveloped fore wing and (4) the coloration of body. Gyranusoidea yunnanensis Xu, sp. nov. can be distinguished from the Gyranusoidea hecale Noyes et Hayat 1988 by (1) 1 brown match between antennal scrobe and orbit; (2) scape 5.0 times as long as wide, and (3) antennal scape without white ring subapically. Both two genara of Dusmetia Mercet, and Gyranusoidea Compere are recorded for the first time in China. All specimens examined are deposited in Institute of Applied Entomology, Agriculture & Biotechnology College, Zhejiang University, Hangzhou, China.
