A new genus of Afrotropical Osminiini, Spatenkana Bartsch, gen. n., is described based on the type species Albuna dybowskii Le Cerf, 1917, which was previously combined with the genus Synanthedon Hübner, [1819]. Moreover, a second species, Albuna africana Le Cerf, 1917, is assigned to the new genus (comb. n.). Both species were only known from the female holotypes. Recently, four specimens of S. dybowskii comb. n., one female each from Zambia, Zimbabwe and Mozambique and one male from South Africa, were discovered. These specimens represent the first records for these countries. Furthermore, they allow a description of the male, the genitalia structure of the female and a classification of this species for the first time.
