An integrated taxonomic revision of the Afrotropical Glostatus Schedl, 1939 is presented, which is based on multiple genetic markers and morphological characters. Both types of data clearly distinguish Glostatus from other genera in Xyloctonini and support a separate placement in subtribe Glostatina trib. n. Six new species are described: Glostatus aculeus sp. n., G. acutidentes sp. n., G. paraxyloctonus sp. n., G. procurvus sp. n., G. tenuis sp. n. and G. tuberculatus sp. n. The synonymising of the genus Stephanopodius Schedl, 1941 with Glostatus involved new combinations and synonyms for Glostatus dispar (Eggers, 1936) comb. n. (= Stephanopodius giganteus Schedl, 1950, syn. n.), Glostatus ghanaensis (Schedl, 1962) comb. n., Glostatus mkulumusius (Eggers, 1919) comb. n. (= Stephanopodius usambaricus Schedl, 1941, syn. n.) and Glostatus nunbergi nom. n. for Stephanopodius squamosus Nunberg, 1973 (nec Glostatus squamosus Schedl, 1962). Other new combinations include Glostatus tredli (Reitter, 1908) comb. n., Glostatus scutiae (Schedl, 1959) comb. n., and Glostatus xanthophloeae (Schedl, 1957) comb. n., all from Hypothenemus Westwood, 1836, and Glostatus giganteus (Schedl, 1950) comb. n. from Cryphalus Erichson, 1836. Addi­tional new synonyms are reported for Glostatus acaciae (Schedl, 1957) (= Glostatus hirsutus Schedl, 1962, syn. n.), Glostatus declividepressus Schedl, 1939 (= Glostatus assimilis Schedl, 1957, syn. n.) and Glostatus pondoanus Schedl, 1958 (= Glostatus squamosus Schedl, 1962, syn. n.; = Hypocryphalus dubiosus Schedl, 1970, syn. n.). A key to all known species is provided together with photographs of all the species.
