The Afrotropical Delia is revised to include 20 species. Six new species are described: madagascariensis, ismayi, pseudoventralis, tibila, endorsina and cameroonica. Three new synonymies are established: Chortophila linearis Adams, 1905 = Hylemyia bracata Rondani, 1866; Hylemyia dispar Bezzi, 1908 = Hylemyia bracata Rondani, 1866; and Hylemyia capensis Malloch, 1924 = Hylemyia urbana Malloch, 1924. Hylemyia arambourgi Séguy, 1938 is resurrected from synonymy. The Delia bracata section is expanded to include a new subsection, the ventralis subsection.
