The most important and reliable characters for specific diagnosis of Hydrellia lie in the very complex male genitalia. In nearly all of the afrotropical species the descriptions of these structures have been inadequate. Of the eighteen species treated here, two, Hydrellia anguliterga and H. feijeni, are described as being new to science, a further two, H. binotata Canzoneri & Meneghini and H. lunata Cresson, are placed in synonymy, supplementary descriptions of male and female genitalia are given, immature stages of three species, H. anguliterga, H. feijeni and H. soikae Cogan, are described and further distributio- nal data for species presented.
