A collection of spiders from Kenya, assembled by Prof. Volker Mahnert and deposited in the Natural History Museum of Geneva, contains 16 identifiable linyphiid species. Among of them a new genus and two new species were revealed: Afrotrichona gen. nov., with Afrotrichona mahnerti sp. nov. as the type species, and Agyneta spinifera sp. nov. Males of Pelecopsis subflavaRussell-Smith & Jocqué, 1986, Lepthyphantes (s. str.) buensisBosmans & Jocqué, 1983, and Machadocara gongylioidesMiller, 1970 are illustrated and briefly redescribed. The latter two species, together with Agyneta habra (Locket, 1968), Metalepthyphantes vicinusLocket, 1968, Microctenonyx subitaneus (O. Pickard-Cambridge, 1875) and P. pasteuri (Berland in Fage & Simon, 1936), are reported for the Kenyan fauna for the first time. In addition, A. spinifera sp. nov. is also reported from Tanzania.
