Metapectal-propodeal disc with strong transverse posterior keel, dull, reticulate rugose; propodeal declivity dull, with two complete longitudinal keels, lateral areas completely reticulate rugose and median area partly shiny and unsculptured. Forewing hyaline, without dark transverse bands; 2r-rs&Rs vein regularly curved with no distinct separation between distal and proximal part; 2R1 cell open. Apex of basivolsella without subdistal inner pointed apophysis ( Fig. 108D ). Tibial spurs 1/1/2.
