T. leptoneura is a true member of the genus Tipula, and apparently the first 

 to be reported from xVustralia. It belongs to a group or subgenus that consists 

 of many African species (T. alphasph Speiser, T. langi Alex., T. rjahoonensis 

 Alex., and others), distinguished by the small size of the cell R-, tbe toothed claws 

 in the males, and the fused scleriles of tbe male hypopygium.
