Description.

Female. Body length 18 mm. Flagellum with 37 segments, bristle-shaped; 1st flagellar segment 3.1 × as long as wide; all segments longer than wide. Temple strongly and almost linearly narrowed behind eye. OED 1.4 × ocellar diameter. Frons almost smooth. Face finely punctate. Clypeus with coarse punctures, slightly convex; apical margin slightly concave. Malar space 1.0 × as long as width of mandibular base. Genal carina reaching hypostomal carina far from mandibular base; both carinae low. Mesoscutum, mesopleuron and metapleuron densely punctate; speculum and surrounding areas smooth and shining. Dorsal end of epicnemial carina reaching centre of frontal margin of mesopleuron. Scutellum strongly pyramidal, without lateral carinae. Propodeum with strong carinae. Area basalis without carina. Area superomedia highly elevated, sickle-shaped, smooth; area petiolaris with coarse transverse rugae. Hind coxa punctate, without scopa. Hind femur slender, punctate, 5.4 × as long as wide. Tarsal claws simple. Areolet large, pentagonal, frontal distance between veins 2rs-m and 3rs-m 2 × diameter of these veins; vein 2m-cu distinctly distal to its middle. Ramellus long. Vein 1cu-a strongly postfurcal by 0.4 × its length.

Metasoma amblypygous. Postpetiole strongly widened, rugose-punctate, with distinct latero-median carina. Gastrocoelus strongly impressed and with longitudinal ridges; thyridium not distinctly separated from gastrocoelus, transverse, 1.2 × as wide as interval. 2nd tergite 0.8 × as long as wide. 2nd to 5th tergites with strong coarse aciculation; 6th and 7th tergites smooth.

Colour. Head, scape, pedicel, mesosoma and 1st and 2nd tergites completely reddish. Palps, mandible, except teeth and facial orbit, yellowish. Flagellum black, in distal half yellowish-brown ventrally. Frons medially and stemmaticum black. 3rd to 7th tergites blackish, with slight violet shine; 6th and 7th tergites posteriorly reddish-yellow. 2nd to 5th sternites pale yellow, 3rd to 5th sternites with triangular lateral black spots. Fore- and mid-legs red. Hind leg mainly black; hind trochanter and trochantellus ventrally yellowish; hind tibia yellow in basal half. Wings yellowish, apices (half the length of distance from areolet to wing apex) brownish.

Male. Body length 16 mm. Flagellum with 33 segments; segments with proximal concavities on inner sides, subapically ± widened. Flagellum entirely black. Structure and colour pattern otherwise as described for ♀.

Remark.

This new species resembles Holcojoppa heinrichi (Uchida, 1940), but differs by the red 2nd tergite, yellow basal half of hind tibia and less extensive blackish apical margins of the wings.
