Antenna clavate; antennomeres in following proportions: 17:8:26:15:13:?:?:8.5:7:9 (antennomeres 6–7 missing in holotype); ADOs present in antennomeres 8–10 (antennomeres 6–7 missing in holotype).

Propleuron almost completely hidden under pronotum; pronotum dull, setose, granulate, slightly humped, crossed by anterior slight transverse impression and posterior deep furrow; posterior collar of pronotum very short, almost absent; pronotal tubercle not reaching tegula. Mesoscutum dull, setose, completely granulate, with lateral regions sculptured by many transverse keels. Notauli almost absent (two very short tracks of notauli shortly visible near anterior margin of mesoscutum). Mesoscutellum dull, granulate. Metanotum dull, reticulate rugose. Metapectal-propodeal disc completely reticulate rugose, shorter than propodeal declivity (20:25); propodeal declivity with two longitudinal keels, with median area dull, reticulate rugose (with areolae less strong than those of lateral regions). Mesopleuron dull, reticulate rugose. Metapleuron dull, granulate and transversely striate. Forewing with one small dark spot around 2r-rs&Rs vein; distal part of 2r-rs&Rs vein slightly longer than proximal part (13:11). Protarsomeres in following proportions: 14:4:7:13:26. Enlarged claw ( Fig. 149B ) without subdistal teeth, with one row of seven bristles in addition to two distal lamellae. Protarsomere 5 ( Fig. 149B ) with two rows of approximately 30 lamellae present continuously to apex (shortest row composed of three very long lamellae, longest row composed of short lamellae forming three rows at apex. Tibial spurs 1/1/2.
