Udinia , an Ethiopian coccid genus, is redefined and a key is given to the thirteen species now recognised: bruncki sp. n. , catori (Green) comb. n. [= Lecanium subhirsutum Newstead syn. n. ], farquharsoni (Newstead) [= U.exoleta (De Lotto) syn. n. ], glabra De Lotto, ikoyensis sp. n. , lobayana (Balachowsky & Ferrero) comb. n. , newsteadi sp. n. , nigeriensis sp. n. , pattersoni sp. n. , paupercula De Lotto, pterolobina De Lotto, scitula De Lotto, setigera (Newstead). Five species are described as new and three species are redescribed and for these lectotypes are designated. The morphological characters used are discussed and listed and intraspecific variations shown by two of the species are tabulated. The distribution of all the species is recorded on two maps and the literature dealing with associations between ants and Udinia and related coccid genera is briefly reviewed.
