Abstract

The leafhopper genus Hadroca Theron, 1974 with type species Euscelis ramosa Naudé, 1926 is re-defined here by examination of long series of specimens with varied color and wing polymorphic males and females. Five new species are added: Hadroca alacaudella sp. nov., H. alavittata sp. nov., H. bualacauda sp. nov., H. hapsistylis sp. nov. and H. treichroa sp. nov. The genus is known only from South Africa, mostly from the Fynbos Biome. All species have the aedeagus C-shaped and uniformly sclerotized, the shaft gradually tapered, commonly edentate, rarely with single, subapical, anterior process and the style with distal apophysis curved ventrad. A key to species is provided, with discussion on the differentiation from similar genera such as Bloemia Theron, 1974, Basutoia Linnavuori, 1961 and Tzitzikamaia Linnavuori, 1961 and distribution maps.
