Head ( Figs 253A, C ) dull, slightly excavated, reticulate rugose and granulate; frontal line complete, slender in anterior third of frons; occipital carina incomplete, only present behind and on sides of lateral ocelli (laterally reaching about 0.7 length of OOL); POL = 1; OL = 1; OOL = 13; lateral ocelli almost touching occipital carina; greatest breadth of lateral ocelli longer than POL (3:1); temple absent. Palpal formula 6/3. Pronotum crossed by strong transverse impression, shiny, unsetose, sculptured by many longitudinal and parallel striae on anterior collar, lateral regions and disc; posterior edges of pronotum rounded, not produced into lobes. Mesoscutum ( Fig. 253A ) dull, unsetose, reticulate rugose. Notauli absent. Mesoscutellum dull, reticulate rugose, except posterior margin unsculptured. Metanotum dull, short, transverse, rugose. Metapectal-propodeal disc dull, reticulate rugose, sculptured by numerous parallel and longitudinal keels (with many transverse keels among longitudinal keels); propodeal declivity with two complete longitudinal keels; median and lateral areas of propodeal declivity rugose. Mesopleuron dull and rugose. Metapleuron sculptured by many transverse keels. Forewing ( Figs 253A, B ) with two dark transverse bands; distal part of 2r-rs&Rs vein much longer than proximal part (27:16). Hind wing with distal third darkened. Protarsomeres in following proportions: 28:4:9:21:35. Enlarged claw ( Fig. 251G ) with one subapical tooth and one row of 15 long and slender lamellae + one long seta. Protarsomere 5 ( Fig. 251G ) with two rows of 8+11 (in holotype) or 8+9 lamellae; apex with at least 14–20 lamellae. Tibial spurs 1/0/2.
