Mesoscutum dull, granulate. Notauli incomplete, approximately reaching 0.75 × length of mesoscutum. Mesoscutellum as sculptured as mesoscutum. Metanotum rugose. Metapectal-propodeal disc reticulate rugose; propodeal declivity reticulate rugose, without longitudinal keels. Forewing with three dark transverse bands; distal part of 2r-rs&Rs vein much longer than proximal part (11:5). Protarsomere 1 longer than 4 (12:9); protarsomere 3 produced into hook. Enlarged claw ( Fig. 135EView FIGURE 135) with one large subdistal tooth and one row of 10 lamellae. Protarso- mere 5 ( Fig. 135EView FIGURE 135) with two rows of about 20 lamellae; apex with approximately 11 lamellae. Tibial spurs 1/1/2.

Head dull, granulate and partly rugose; frontal line complete; occipital carina incomplete, laterally not reaching eyes and temple; POL = 5; OL = 2; OOL = 3.5; OPL = 0.5. Mesoscutum, mesoscutellum and metanotum granulate, slightly rugose. Notauli incomplete, reaching approximately 0.70–0.75 × length of mesoscutum. Metapectal-propodeal disc and propodeal declivity dull, reticulate rugose. Forewing hyaline, without dark transverse bands; distal part of 2r-rs&Rs vein longer than proximal part (9:7); 2R1 cell open. Genitalia in Fig. 137AView FIGURE 137. Tibial spurs 1/1/2.
