Diagnostic characters (modified from JEŽEK & TKOČ 2012). Eyes contiguous; postocular setae arranged in single row; flagellomeres asymmetrically nodiform; second flagellomere with neck twice as long as its diameter; flagellomeres generally with ring of many multibranched ascoids; subcostal and cubital areas of wing wide; radial fork distad of medial fork; gonostylus simple or bifurcate.
