Nervellus of hind wing ± inclivous, intercepted in its apical 0.6–0.7. 1 st tergite 1.6–1.8× as long as wide, without latero-median carina. 2 nd tergite 1.1–1.2× as wide as long.

Color: black. Flagellum reddish, infuscate basally. Palps, mandible except teeth, clypeus (often with baso-median dark spot), sometimes ventral margin and/or oblique paramedi- an spots on face, often hind edge of pronotum and tegula yellow. Scape often reddish ventrally. 1 st tergite except base and 2 nd to 4 th tergites entirely red. Coxae, trochanters and trochantelli black (mid trochantellus sometimes yellowish); legs red; fore and mid tibiae and tarsi ± yellowish; hind femur red, slightly infuscate apically, hind tibia yellow, black in apical 0.2; hind tarsus black. Pterostigma yellow.

♁. Body length 7.0-9.0 mm. Flagellum with 39–42 segments; 1 st flagellar segment 5.2× as long as wide and 1.9× as long as 2 nd segment; 2 nd segment 2.8×, 3 rd segment 2.5× and preapical segment c 2× as long as wide. Temple distinctly and roundly narrowed behind eye. OED 1.2–1.3×. Clypeus moderately convex, with small flat extension laterally. Lower mandibular tooth slightly larger than upper tooth. MI 0.25.

Mesopleuron granulate and with superficial punctures, ± shining, with some fine striae dorsally. Speculum with microsculpture, shining. Hind femur 4.5–4.8× longer than wide. Area superomedia without lateral carina; area petiolaris with complete carina. 1 st tergite 2.2–2.5× as long as wide, without latero-median carina. 2 nd tergite 1.1–1.2× as long as wide.

Color: black. Flagellum ochreous, ± infuscate basally and dorsally. Palps, mandible except teeth, clypeus, malar space, face, scape and pedicel ventrally, rarely anterolateral spot of mesoscutum, wide hind edge of pronotum and tegula, usually fore and mid coxae entirely and all trochanters and trochantelli yellow. 2 nd to 4 th tergites red. Hind coxa black, rarely with reddish spot dorsally; femora, tibiae and tarsi reddish; hind femur usually red, slightly infuscate apically or sometimes entirely black; hind tibia yellow or reddish-yellow (rarely reddish), infuscate in apical 0.3; hind tarsus black. Pterostigma yellow.
