Abstract
The following leafhoppers (Deltocephalinae: Bonaspeiini) of the Fynbos Biome of South Africa are treated: Colistra parvulus (Linnavuori, 1961) is redescribed and three new species of Colistra Davies are described, i.e., C. acapitatus sp. n., C. bucapitatus sp. n. and C. semialius sp. n.; four species of Proekoides Stiller, 1986 are reviewed with the addition of P. postspina sp. n.; Proekes cephaleus (Naudé, 1926) is redescribed with details of the female ovipositor, and three new species, i.e., P. hemiplatyphalis sp. n., P. tetracaphalis sp. n., P. diacaphalis sp. n.; a new genus, Xhoreus gen. n. is described with one new species, X. ulosentus sp. n. All species are of similar appearance, size and with reduced hind wings. Two species, C. acapitatus and C. bucapitatus, were collected on Rooibos tea. Keys are provided to species of Colistra, Proekes and Proekoides. Distribution models show limited ranges in the Western Cape province and confined to the Fynbos Biome while Xhoreus ulosentus is possibly endemic to the Cape Peninsula. The validity of the tribe Bonaspeiini is discussed.
