Abstract Ingcainyenzane irhiniensis n. gen., n. sp. and Ingcainyenzane nolukhanyoensis n. gen., n. sp. are described from Eastern Cape and Ingcainyenzane umgeniensis n. gen., n. sp. is described from KwaZulu-Natal, South Africa. Notes on its biology of the species and a key to species of the genus are also provided. Key words: New genus, new species, taxonomy Introduction The Cicadettini Buckton, 1890 is the most diverse tribe of cicadas (Marshall et al. 2018). A comprehensive study of the tribal relationships and diversification of members of the tribe Cicadettini has shown that all South African Cicadettini have a common ancestor (Marshall et al. 2015a; 2015b). Although it does not hold for all genera (e.g., Gogala et al. 2017), the number of apical cells in the wings has been a common way to distinguish genera of Cica- dettini (e.g. Moulds 2012). The genera of African Cicadettini have also been differentiated in this manner (Distant 1907a; 1920; Dlabola 1963; Sanborn and Villet 2020). The genus Buyisa Distant, 1907a was erected for a single species of small South African cicada that has short and broad fore wings with seven apical cells and hind wings with five apical cells with a second species under review (Sanborn and Villet in press). The single species of Stel- lenboschia Distant, 1920 exhibits eight apical cells in the fore wing and five apical cells in the hind wings. Finally, Pinheya Dlabola, 1963 and Afromelampsalta Sanborn and Villet, 2020 (except A. mimica (Distant, 1907b) that may represent another genus) have the general generic pattern of the tribe with eight and six apical cells in the fore and hind wings respectively. We have begun to describe new taxa of African Cicadettini (Sanborn and Villet 2020; in press) and continue the process here with the description of a new genus and three new species of Cicadettini. The new genus and species differ from the majority of the known African Cicadettini genera by the number of apical cells in the fore wing and hind wings continuing the differentiation of taxa by wing morphology. Materials and methods We describe here two taxa that we collected in Eastern Cape, South Africa and one that was part of a shipment of undetermined cicadas from the Bohart Museum of Entomology, University of California at Davis (UCDC). Type material is deposited in the Albany Museum, Makhanda, South Africa (AMGS), the UCDC, or the Sanborn collec- tion, Miami Shores, USA (AFSC). Vernier calipers (accurate to ±0.05 mm) or a hand-held microscale (accurate to ±0.01 mm) under a dissecting microscope were used to obtain morphological measurements. Anatomical terminol- ogy follows Moulds (2005; 2012).
