Abstract
Three new rust species were collected in the northern part of Namibia: Diorchidium baphiae on Baphia massaiensis (Fabaceae), Phakopsora capriviensis on Bridelia cathartica (Euphorbiaceae), and Ravenelia acaciae-nigrescentis on Acacia nigrescens (Fabaceae, Mimosoideae). For Newinia kigeliae, the uredinial stage is described for the first time. The following species are recorded for the first time from Namibia: Maravalia lonchocarpi, Puccinia magnusiana, P. xanthii, R. modesta, R. pretoriensis, Uromyces dactyloctenii, and U. pretoriensis. Furthermore, the new combination D. dalbergiellae is proposed, and the teleomorph name Ph. brideliae is validated by the description of the telial stage.
