Abstract

Two new genera, Barclayanthus Borovec & Skuhrovec, gen. nov. and  Janakius Borovec & Skuhrovec, gen. nov., assigned to the tribe Trachyphloeini Lacordaire, 1863, are described for three South African species of weevil: Barclayanthus micros Borovec & Skuhrovec, sp. nov., B. cooteri Borovec & Skuhrovec, sp. nov. and Janakius sylvaticus Borovec & Skuhrovec, sp. nov. All species are illustrated and keyed. The taxonomic status of each of the new genera is discussed, and compared with similar genera of Trachyphloeini and Embrithini Marshall, 1942. A key to known small terricolous South African genera of both Trachyphloeini and Embrithini is included.
