We discuss all nominal species of Modicogryllus from the Afrotropicslisted by Chopard(1967) in his catalogue, as well as fourteen new species discovered in eastern and southernAfrica. We have examined and comparedthe types of all species. Nine nominal species are moved out of this genus (see list below). Five additionalAfrican species have not been studied, either because they are from northAfrica or because the types are females; their generic status remains uncertain.Two species are moved into Comidogryllus,previously known only from Australasia. One species, royi, is moved to a new genus Modicoides.
