This monograph presents a comprehensive revision of the tribe Phaeogenini (Ichneumonidae: Ichneumoninae) in the Afrotropical region. The tribe encompasses about 10% of the species within the subfamily, most of them exhibiting an unusual habitus, which makes them readily identifiable within Ichneumoninae. Lusius and Arearia are for example highly speciose genera whose taxonomic placement has oscillated over the years. Of the 32 genera and about 400 species included in the tribe to date, seven genera and 11 species were previously reported from the Afrotropical region. We describe a new genus, record two additional genera and describe 12 new species elevating these totals to 10 and 23, respectively. Both dichotomous and matrix keys are provided to facilitate their identification. All taxa are fully illustrated with high quality images. These images and online keys are freely available on the Iziko South African Museum website www.waspweb.org.
