Description.

Female.

Head: Mandibles mostly densely and coarsely punctate, very finely shagreened at apex. Labrum 6.3 times as long as basally broad (Fig. 6). Maxillary and labial palpi slender and moderately long. Clypeus with lower margin truncated (Fig. 6), smooth in lower 0.2. Face with weak median tubercle in its upper part. Inner eye orbits moderately concave at level of antennal insertions. Vertex and genae with dense and sharp punctures (distance between punctures mostly equal to or slightly longer than diameter of puncture), smooth between punctures; punctures in lower part of genae sparser. Gena, in dorsal view, rounded, about as long as eye width (Fig. 3). Lateral ocellus separated from eye margin by distance equal to maximum diameter of ocellus. Flagellum of antenna with 46 flagellomeres; the basal flagellomere about 2.5 times as long as broad; flagellomeres 4+ distinctly transverse, mid flagellomeres almost twice as broad as long (Fig. 2).

Mesosoma: Pronotum mediodorsally smooth, laterally deeply concave. Mesoscutum weakly convex, posterolaterally with a sharp flange, entirely densely and sharply punctate, smooth between punctures. Scutoscutellar groove deep and smooth. Scute llum moderately convex in lateral view, smooth, with sharp punctures and with lateral carinae only at its extreme base. Mesopleuron mostly densely and sharply punctate, smooth and impunctate only posteriorly. Propodeum dorsally polished, laterally and posteriorly finely punctate to coriaceous. Metapleuron smooth, in dorsoposterior 2/3 with sparp punctures, in ventroanterior 1/3 impunctate.

Metasoma: Tergite 2, in dorsal view, slightly transverse; laterotergite 2 parallel-sided, 3.8 times as long as broad. Tergite 3 with laterotergite rather narrow and parallel- sided. Tergite 1 dorsally predominantly finely and densely punctate, smooth and shining between punctures. Tergites 2-6 dorsally mostly finely and very densely punctate, weakly polished between punctures. Subgenital plate finely punctate.

Coloration: Body and legs almost entirely black (Fig. 1). Flagellum yellowish brown with the basal and the apical flagellomeres fuscous (Fig. 2). Mouth parts blackish. Wings yellow with distal margin broadly infuscate, pterostigma and most of veins pale brown (Fig. 8). Legs predominantly black; fore leg with femur yellowish brown apically, tarsus yellowish brown, partly infuscate; mid leg with femur apically, tibia basally and basitarsus basally yellowish brown; hind leg with tibia with broad subbasal yellowish brown band and basitarsus basally yellowish brown. Tergite 1 with broad posterior brownish yellow band; tergite 2 laterally yellowish brown (Fig. 11).
