Taxonomic revision of the genus Lasiocnemus (Loew, 1851) (Diptera: Asilidae: Leptogastrinae)

The Afrotropical Asilidae genus Lasiocnemus (Loew, 1851) is revised. Seven species are recognized (La. fascipennis Engel & Cuthbertson, 1939; La. griseicinctipes Speiser, 1913; La. hermanni Janssens, 1952; La. hyalipennis Janssens, 1952; La. lugens Loew, 1858; and La. obscuripennis (Loew, 1851)), one of which is newly described from Kenya, Somalia, South Africa, and Tanzania, La. londti sp. n. La. anthracinus Janssens, 1952, is synonymized with La. griseicinctipes Speiser, 1913. Redescriptions and descriptions of the genus and all species as well as an identification key to species are provided. Distribution, occurrence in biodiversity hotspots, seasonal incidence, and biology are discussed.
