Acostemminae Evans, 1972

Erected by Evans (1972b) for eight small, mainly monobasic, African and Madagascan genera. The subfamily is considered, by Linnavuori & Al-Ne'amy (1983a), to have arisen in the Malagasian subregion from where it has recently radiated into Africa and the Oriental Region. The African and Madagascan species have been reviewed, in part, by Evans (1954a, 1959a), Linnavuori & Quartau (1975a) and Linnavuori & Al-Ne'amy (1983a). The subfamily is represented in the SE Asian/Pacific area by the monobasic genus Telopetulcus, in New Guinea. The biology of this subfamily is unknown. There are no tribes.
