A revision of the Afrotropical species of Philonthus (s. str.) turbidus species-group (Coleoptera: Staphylinidae: Philonthina)

Abstract: The turbidus group of the nominotypic subgenus of the genus Philonthus Stephens, 1829, is revised. The group comprises 11 Afrotropical species. Five of them are described as new: Philonthus (s. str.) camelus sp. n. (Tanzania: Kilimandjaro), Philonthus (s. str.) pan sp. n. (Botswana, Malawi, Namibia, Republic of South Africa, and Zambia), Philonthus (s. str.) papio sp. n. (Republic of Guinea), Philonthus (s. str.) psittacus sp. n. (Zambia), and Philonthus (s. str.) xerus sp. n. (Sudan). The remaining six species are redescribed: P. (s. str.) bulbifer Tottenham, 1956, P. (s. str.) musurus Tottenham, 1956, P. (s. str.) ramosus Levasseur, 1968, P. (s. str.) stysi Hromádka, 1980, P. (s. str.) tumulinus Tottenham, 1955, and P. (s. str.) turbidus Erichson, 1840. The male genitalia of all species and morphological details of some species are illustrated and identification keys to all species are provided.
