10 December 2007 Morphological Differences between Three South African Species of Evides Dejean, 1833 (Coleoptera: Buprestidae)
Author Affiliations +

The genus Evides Dejean, 1833 (Coleoptera: Buprestidae) belongs to the family of wood-boring beetles commonly known as jewel beetles. This comparative study was undertaken on the morphological characteristics of three species from field specimens, private collections and collections at the Transvaal Museum of Natural History. The genus Evides consists of eleven species and one subspecies in total worldwide. Nine species and one subspecies are endemic to Sub-Saharan Africa. One species is recorded from India and further species from Laos and Vietnam: Bellamy (World Catalogue, in prep.) The objective of the study was to quantify morphological differences between species representing the genus in South Africa. Specimens of E. gambiensis (Laporte & Gory, 1835), E. interstitialis (Obenberger, 1924) and E. pubiventris (Laporte & Gory, 1835) were collected in the Waterberg (Limpopo Province) and additional specimens of E. pubiventris were collected at Ezemvelo Nature Reserve (Gauteng Province). All three species are related, difficult to differentiate in the field and occur on the same host plants, marula (Sclerocarya birrea (A. Rich.) Hochst.) and false marula (Lannea discolor (Sonder) Engl.). Results indicate that there are morphological differences and species can be differentiated according to elytra length, total elytron width, eye size, frons length, frons width and abdomen length.
