Styringomyia bipunctata group ( Figs 33-44 )

The males of the three species, Styringomyia bipunctata , S. coronata , and S. williamsi , share a long wide tergite 9/10 with ear-like lateral expansions. Sternite 9 is trapezoidal, almost hemispherical ending in three lobes, the lateral ones strongly setose. The gonocoxites are evenly curved, almost conical with more than basal half markedly expanded and with rather slim apical spine. The gonostyli include only a single element, slightly curved, subbasally expanded, with some setae and short spines. The known females have apparently two-segmented cerci that reach backward well beyond the tips of the slightly sinuously curved, rather deep hypogynial valves.
