Thorax black; pronotum, tegula, lateral half of lateral lobe of mesoscutum, medial lobe of mesoscutum at extreme angle, and postspiracular sclerite orange-yellow. Legs black; anterior surface of apical half and apex of posterior surface of fore femur yellow, fore tibia and fore basitarsomere at base dirty whitish. Wings uniformly slightly infuscate; stigma, costa, subcosta and rest of venation blackish. Abdomen black.
Head very slightly narrowed behind eyes. Antenna 1.4 times as long as maximum head width; flagellomere 1 as long as flagellomeres 2/3 combined. POL:OOL = 1.0:0.7. Postocellar area: width:length = 1.0:0.7, lateral furrows slightly convex. Supra-antennal grooves large and deep, with conspicuous furrow at lateral margin of torulus. Interantennal area with rounded groove and small longitudinal furrow medially, ending at front margin of frontal area. Eyes converge downwards, lower interocular distance 1.1 times the length of the eye. Supraclypeal furrow deep.
Head sparsely micropunctate, shiny; pubescence on head brown, longer than diameter of lateral ocellus. Thorax more densely punctate, shiny; pubescence yellow, shorter than that on head. In fore wing, cells 1Rs and 2Rs subequal in length; stub of 2A+3A furcate ( Fig. 20 View Figs 20–23 ).
Tergum 1 with wide and deep medial excision. Terga 1/2 smooth and shiny, following terga transversally microridged and micropunctate, shiny. Sawsheath in lateral view narrowly rounded at apex ( Fig. 21 View Figs 20–23 ), in dorsal view narrowed toward apex.
