The species of the genus Atanycolus Foerster (Hymenoptera, Braconidae, Braconinae) from China are revised and six species are recognized, including one new species (A. grandis Wang & Chen, sp. n.), which is described and illustrated in this paper. Three species, i.e. A. crenulatus Telenga, 1936, A. lindemani Tobias, 1980 and A. sculpturatus (Thomson, 1892), are reported from China for the first time. A key to species of this genus is provided.
