Mesoscutum ( Fig. 123A ) dull, granulate. Notauli incomplete, reaching approximately 0.65 × length of mesoscutum. Mesoscutellum and metanotum dull, granulate. Metapectal-propodeal disc reticulate rugose; propodeal declivity reticulate rugose, without longitudinal keels. Forewing ( Fig. 123C ) with two dark transverse bands; distal part of 2r-rs&Rs vein more than 3 × as long as proximal part (17:5). Protarsomere 1 about as long as 4 (17:16); protarsomere 3 produced into hook. Enlarged claw ( Fig. 121D ) with one large subdistal tooth and one row of 11 lamellae (lamellae situated near subdistal tooth very long and similar to peg–like setae).
