Metapectal-propodeal disc reticulate rugose; propodeal declivity reticulate rugose, with two long longitudinal keels and median area rugose. Forewing hyaline, without dark transverse bands; pterostigma about 5 × as long as broad (14:2.5). Protarsomere 1 shorter than 4 (11:14). Protrochanter about twice as long as broad (8:4). Enlarged claw ( Fig. 147B ) without subdistal teeth and lamellae, with many bristles. Protarsomere 5 ( Fig. 147B ) with 2–3 rows of approximately 63 lamellae extending continuously to apex. Tibial spurs 1/1/2.

Head black, except mandible yellow; antenna with antennomeres 1–6 yellow (antennomeres 7–10 missing in unique known ♂); mesosoma black; metasoma brownblack; legs yellow. Antennomeres 1–6 in following proportions: 5:4:14:10:10:9. Head reticulate rugose; mandible tridentate, with one rudimentary intermediate tooth ( Fig. 8D ); occipital carina complete, reaching posterior margins of eyes; temple absent. Mesoscutum reticulate rugose. Notauli very slightly visible only on anterior half of mesoscutum. Mesoscutellum granulate. Metanotum reticulate rugose. Metapectal-propodeal disc reticulate rugose; propodeal declivity reticulate rugose, without longitudinal keels. Forewing hyaline, without dark transverse bands; pterostigma more than 3 × as long as broad (25:7). Tibial spurs 1/1/2.
