Abstract
Based on examination of type species, the subgenera of South African genus Stenomastigus Leleup are merged and the name Acanthostigus Leleup is placed as a junior synonym of Stenomastigus. A group of species characterized by a prominent distal projection of the male protrochanters is revised and two new species are described: S. berlinafricanus sp. n. and S. kosianus sp. n. New diagnoses of S. allaeri Leleup, S. basilewskyi Leleup and S. kochi Leleup are given. Habitus, aedeagi, modified fore legs and other diagnostic characters of all treated species are illustrated.
