Mesoscutellum with 3 pairs of setae. Fore wing ( Fig. 17 ) 2.36̄2.54× as long as wide, stigmal vein ( Fig. 17 ) with a distinct neck. Ovipositor ( Fig. 19 ) short and wide, directed upwards in lateral view, originating from TIV, much shorter than (0.56×) mesotibia. Second valvifer 3.92̄4.07× as long as third valvula. Third valvula short, membranous, tip not reaching the apex of T9, lateral margins of T9 well sclerotized and thickened. Male. Unknown.
