(Schönherr) and Weise are recognized as two prominent pest species on beans ( (L.), Fabaceae), in Central and East Africa. These beetles destroy root tissue and seedlings, skeletonize the leaves of plants and feed on inflorescences, causing serious crop losses. Both species also feed on cowpeas ( (L.) Walp. (Fabaceae). is known to be a vector of several plant viruses. The current taxonomic status of the African genus is discussed, and the following species are transferred from the genus Chapuis to Dejean as new combinations: (Laboissière), (Laboissière), (Jacoby), (Jacoby), (Jacoby), (Laboissière), (Laboissière), (Laboissière), (Chapuis), (Jacoby), (Laboissière), and (Laboissière). nom. n. is proposed as the replacement name for (Laboissière) comb. n. (from ), a junior homonym of Laboissière. and have been studied to provide information and illustrations to facilitate their identification. sp. n. is described as a new pest species of beans and cowpeas from southern Africa.
