Bembidiina of Afrotropical Region. 2 Odontium subg. Microserrullula Netolitzky, 1921 (Coleoptera, Carabidae, Bembidiina)

The afrotropical species of the subgenus Microserrullula netolitzky, 1921, of the genus Odontium LeConte, 1848 are here revised. We redescribe the three-known species, Odontium aegyptiacum (Dejean, 1831), O. icterodes (Alluaud, 1933) and O. pogonopsis (Alluaud, 1933), and describe four new species: Odontium australe n. sp. (Kenya, Mozambique, Madagascar, South africa); Odontium basilewskyi n. sp. (Democratic Republic of Congo); Odontium okavangum n. sp. (angola, namibia, Zambia); Odontium clarkei n. sp. (Ethiopia). A key for the identification of the african species of the subgenus Microserrullula is presented.
