A review of the Acridinae s. str. (Orthoptera: Acridoidea: Acrididae) of eastern Africa with taxonomic changes and description of new taxa

Abstract

The Acridinae of eastern Africa are reviewed and recognized as comprising 42 core genera, belonging to five different tribes, together withXerophlaeobaandDorsthippus, 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:Anacteanagen. n.:A.hollisisp. n.andA.neaveiburttisubsp. n.;Brachybothrusgen. n.:B.phyllopterussp. n.andB.holasp. n.;Coryphosimastenopteracoloratasubsp. n.;Duroniachloronotaphippsisubsp. n.;Oxyduroniagen. n.:O.anablepioidessp. n.;Sumbaexilissp. n.Nine new synonyms are recognized:SumbalongicornisRamme, 1929 =S.roseipennisI.
