| description | The southern African species of the genus <i>Rhamphus</i> Clairville, 1798, is herein revised for the first time. Fourteen species are recognized, 13 of which are new to science. The single known species was <i>Rhamphus namibicus</i> Korotyaev, 1994 (Namibia), whereas the new species are <i>R. carinatus</i> sp. nov. (South Africa: Limpopo; Zimbabwe), <i>R. densepunctatus</i> sp. nov. (South Africa: Western Cape), <i>R. gigas</i> sp. nov. (Zambia), <i>R. glaber</i> sp. nov. (South Africa: Mpumalanga), <i>R. globipennis</i> sp. nov. (South Africa: Mpumalanga, Limpopo, KwaZulu-Natal, Eastern Cape, Western Cape), <i>R. hispidulus</i> sp. nov. (South Africa: Eastern Cape), <i>R. indifferens</i> sp. nov. (South Africa: Gauteng, KwaZulu-Natal, Eastern Cape), <i>R. levipennis</i> sp. nov. (South Africa: Mpumalanga; Zimbabwe), <i>R. longitarsis</i> sp. nov. (Southern Namibia; South Africa: Northern Cape), <i>R. obesulus</i> sp. nov. (South Africa: Eastern Cape), <i>R. pilosulus</i> sp. nov. (South Africa: Mpumalanga, KwaZulu-Natal; Zimbabwe), <i>R. scaber</i> sp. nov. (South Africa: KwaZulu-Natal, Eastern Cape), <i>R. squamidorsum</i> sp. nov. (South Africa: Eastern Cape, Western Cape). Based on morphological characters, the species are separated into four informal groups. In considering possible relationships between these species and those from other regions, host-plant associations are also discussed. |
