Abstract

The Acridinae of eastern Africa are reviewed and recognized as comprising 42 core genera, belonging to five different tribes, together with Xerophlaeoba and Dorsthippus, which are unclassified but appear to be related to some extra-limital genera. Keys are given to tribes and genus groups as well as to genera and, where necessary, species within each genus.

The following new taxa are described: Anacteana gen. n.: A.hollisi sp. n. and A.neaveiburtti subsp. n.; Brachybothrus gen. n.: B.phyllopterus sp. n. and B.hola sp. n.; Coryphosimastenopteracolorata subsp. n.; Duroniachloronotaphippsi subsp. n.; Oxyduronia gen. n.: O.anablepioides sp. n.; Sumbaexilis sp. n.

Nine new synonyms are recognized: Sumbalongicornis Ramme, 1929 = S.roseipennis I. Bolívar, 1912, syn. n.; Orthochiristavariegata Sjöstedt, 1931 = Gymnobothruslineaalba I. Bolívar, 1889, syn. n.; Orthochiristaelgonensis Sjöstedt, 1931 = Gymnobothruslineaalba I. Bolívar, 1889, syn. n.; Gymnobothrusgracilis (Ramme, 1931) = Gymnobothrusanchietae I. Bolívar, 1889, syn. n.; Gymnobothrussubcarinatus (I. Bolívar, 1922) = Gymnobothrusflexuosus (Schulthess, 1898), syn. n.; Gymnobothroidesmontanus Kevan, 1950 = Gymnobothruslevipeslevipes (Karsch, 1896), syn. n.; Gymnobothroideskeniensis Johnston, 1937 = Gymnobothruslevipesabbreviatus (Chopard, 1921), syn. n.; Gymnobothroides Karny, 1915 = Gymnobothrus I. Bolívar, 1889, syn. n.; Phloeochopardia Dirsh, 1958 = Gymnobothrus I. Bolívar, 1889, syn. n.
