Public understanding of the goals of applied biology and conservation is promoted by showcasing charismatic or significant organisms using vernacular names. Conservation activities in the province of KwaZulu-Natal, South Africa, are prioritising taxa that have high rates of provincial endemism, such as snails, earthworms, millipedes and cicadas. To assist wider public engagement in these activities, an assessment of endemism of the cicadas of KwaZulu-Natal is presented along with a dichotomous, 37-couplet key for the identification of males, based mainly on externally visible morphology and colouration. Standardised English vernacular names coined following a simple naming convention are proposed. Forty-two percent (16 out of 38) of the cicada species known from KwaZulu-Natal are endemic to the province. Photographs of some of the species are included to facilitate their identification. Photographs can be used for identification of various species providing that the diagnostic characters are visible in the photographs. For this purpose, photographs may have to be taken of hand-held individuals. Some of the endemic species are of particular concern for conservation because they are not known to occur in statutory protected areas or are only known from relatively small protected areas. The latter may not be able to ensure the long-term survival of the species. The rate and extent of loss of habitat outside protected areas is likely to be a grave threat to species that are not protected or that are inadequately conserved in statutory protected areas. The standardised vernacular names proposed here provide a tool for communicating provincial conservation plans and concerns with stakeholders in KwaZulu-Natal and for stimulating interest in cicadas amongst land users, environmental impact assessment practitioners, biologists, naturalists and citizen scientists.
