The Leucosphyrus Group of the genus Anopheles, subgenus Cellia, is divided into three subordinate groups based upon an analysis of relative lengths of the female proboscis, maxillary palpus and forefemur, and the relationships among them. The Elegans, Leucosphyrus and Riparis Subgroups are proposed and currently recognized taxa are assigned to each. Assignment of species to the Dirus and Leucosphyrus Species Complexes is also indicated. The relationships of the subgroups are figured, and a listing of currently recognized taxa belonging to the Leucosphyrus Group is tabulated.
