Styringomyia bancrofti group ( Figs 7-23 )

Four species, Styringomyia bancrofti , S. baroalba , S. collessi and S. remex , have femora and tibiae yellowish with more or less complete, distinct dark rings and the wings spotted grey at the cross-veins. In the males sternite 9 terminates in two digitate lobes, each with apical seta and separated by a distinct median notch. These species also have approximately conical gonocoxites with wide mesal lobe and rather thick apical spine, and their gonostyli include several comb-shaped elements. The cerci of the known females are apparently bifurcate with each tip bearing an apical spine, the hypogynial valves are slightly and evenly curved dorsally and rather shallow. S. edwardsorum is also included in the group even though, owing to the nature of the preservation of the type material, some of the above characters cannot clearly be detected.
