Information relating to the Afrotropical asilid genus Congomochtherus Oldroyd, 1979 is updated. Seven species are recognised (acuminatus, elferinki, inachus, lobatus, oldroydi, penicillatus, potamius). Heligmonevra rufinota Martin, 1964, which has been transferred to the genus, is digeneric and has consequently been reassigned to Heligmonevra Bigot, 1858. All records of species are provided together with maps showing their distributions. The close association of this genus with freshwater habitats is discussed.
