The species of the two genera of Khoikhoiinae (Hymenoptera, Braconidae) are revised. Thirteen species are recognized, of which five are new and eight were previously described: Khoikhoia anthelion Sharkey, sp. n., K. lission Mason, 1984, K. oligospilos Sharkey, sp. n., K. semiadusta Mason, 1983, K. solata Mason, 1983, K. townesi Mason, 1983, K. turneri Mason, 1984, Sania browni Sharkey, sp. n., S. capensis Mason, 1983, S. henryi Mason, 1983, S. marjoriae Mason, 1983, S. masneri Sharkey, sp. n., and S. masoni Sharkey, sp. n.. All are from the Cape Region of South Africa, and all but one species are confined to the western Cape. A dichotomous key to species is presented; links to electronic interactive keys and to distribution maps are also included. Based on phylogenetic position and morphological characters, speculations on life history are made, and it is suggested that some species may be parasitoids of wood- or stem-boring Lepidoptera. The DELTA data matrix and images for the key are available at 10.3897/zookeys.20.108.app.1.ik; Intkey files are available at 10.3897/zookeys.20.108.app.2.ik; Lucid files in LIF and SDD format are available at doi:10.3897/zookeys.20.108.app.3.ik and doi:10.3897/zookeys.20.108.app.4.ik. Publishing of DELTA raw data will facilitate future workers to edit keys and to add newly discovered taxa.
