oa Journal of the Entomological Society of Southern Africa - Identification of the subgenus stegomyia in Southern Africa, and keys to the species
Adults are recognized by their sooty black colour, sometimes with bronzy sheen, unspeckled wings, and conspicuous white and sometimes yellow marking. There are white basal bands on at least the first two tarsal segments of the hind legs, and broad or narrow bands on some of the other tarsal segments, which may also be all, or nearly all, white. On most, there is a pair of large sub-lateral white patches on the anterior half of scutum, but exceptions to the latter ornamentation are unilineatus and vittatus.
