The pseudonigeria group of the subgenus Stegomyia Theobald (genus Aedes Meigen) is characterized. A key to identify the species is provided. Information on the present status of the pseudonigeria group of species is summarized. Aedes (Stegomyia) mickevichae, a new species from Kenya, is recognized. Aedes (Stegomyia) pseudonigeria (Theobald) from Angola is shown to be distinct and a new closely related species, Aedes (Stegomyia) saimedres, is recognized. The distributions of mickevichae, pseudonigeria and saimedres are based on examined specimens.
