Head 0.6 × as long as wide in dorsal view. Clypeus 2.1– 2.35 (HT: 2.35) × as wide as long; slightly convex in lateral view; sparsely punctate dorsally; smooth ventrally; lower margin weakly rounded in frontal view, obtuse in lateral view. Face 0.38–0.4 (HT: 0.38) × as long as minimum width; weakly convex medially; matt; sparsely punctate. Anterior tentorial pit large. Frons weakly concave above antennal sockets; matt and punctate dorsally, coriaceous to smooth ventrally except for finely rugose medially. POL 0.9 × as OD. OOL 1.25–1.6 × as OD. Gena and occiput finely punctate. Dorsal profile of gena rounded in dorsal view; width gradually narrowing posteriorly ( Fig. 24D). Occipital carina complete. Malar space 1.05–1.2 (HT: 1.2) × as long as basal width of mandible. Mandible flat at base; lower tooth shorter than upper tooth. Antenna with 24–25 (HT: 25) flagellomeres; apical part flattened below and tapped to slender apex ( Fig. 24A). FL I 2.2–3.0 (HT: 2.2) × as long as maximum depth in lateral view, 0.9–1.0 (HT: 1.0) × as long as FL II.

Mesosoma finely punctate. Pronotum foveolate ventrally, smooth dorsally except for dorsal margin ( Fig. 24E). Epomia long; dorsal end closed to dorsal margin of pronotum. Mesoscutum with short and sharp notaulus ( Fig. 24D). Scutellum punctate anteriorly, smooth posteriorly; weakly convex in lateral view. Mesopleuron with small conspicuous smooth area around speculum ( Fig. 24E). Epicnemial carina present laterally and ventrally. Sternaulus deep entire length of mesopleuron. Metapleuron sparsely and finely punctate; with complete juxtacoxal carina. Propodeum finely and sparsely punctate; ISP smooth; with all carinae ( Fig. 24G); area superomedia clearly defined, 1.5 × as long as maximum width; apophysis small and obtuse; spiracle oval. Fore wing length 5.0–5.1 (HT: 5.0) mm. Areolet shorter than maximum width; width slightly narrowing anteriorly; received vein 2m-cu basal than middle ( Fig. 24F). Fore wing vein 1cu-a interstitial to vein M&RS ( Fig. 24F). Nervellus inclivous; intercepted near posterior end of vein. Hind femur reticulate coriaceous; 5.0–5.1 (HT: 5.0) × as long as maximum depth in lateral view. Dorsal face of tibiae without robust, large, conspicuous setae. Tarsal claws simple.

Metasoma finely and densely punctate; ISP smooth. T I 3.8–5.1 (HT: 5.1) × as long as maximum width, sparsely punctate; latero-median carina absent; dorso-lateral carina weakly and partly present. T II 0.9–0.95 × as long as maximum width. Thyridium present; close to anterior margin of T II; slightly depressed; ca. 1.0 × as wide as length. Ovipositor sheath 0.8–1.05 (HT: 1.05) × as long as hind tibia, 1.5–1.9 (HT: 1.9) × as long as T I. Ovipositor straight; apex sharp; apex of lower valve with teeth ( Fig. 78S).

Colouration ( Figs. 24A–G). Body (excluding wings) black to blackish-brown. Setae silver. Mandible, clypeus, and membranous part of metasomal sternites partly tinged with dark yellowish-brown except for apex of former. Median part of face slightly tinged with dark yellowish-brown. FL V (or VI) to FL X with white markings. Scutellum yellow. Postscutellum tinged with yellow to dark yellowish-brown. Subtegular ridge and tegula yellowish-brown. Legs yellowish-brown to reddish-brown; femora, hind coxa, hind tibia, and hind tarsus sometimes darkened. Base of T I white. T I except for white base and T II red to reddish-yellow. Subapical part of T I and basal part of T II sometimes each with brownish area. T III and T IV sometimes slightly tinged with red. Median parts of T VII and T VIII white. Ovipositor reddish-brown. Wings hyaline. Veins and pterostigma yellowish-brown except for yellow wing base.

Male. Unknown.

Distribution. Japan (Honshu).

Bionomics. Unknown.

Etymology. The specific name is a traditional Japanese term “Kurenai”, which means red.

Remarks. Propodeal spiracle of the paratype is situated on the mid-length between pleural carina and lateral longitudinal carina, while the other characters of this specimen are well accorded of the character states of Giraudia . This species resembles Gi. plana (Provancher, 1874) and Gi. nana sp. nov., in the yellow scutellum and the absence of robust, large, conspicuous setae of tibiae, but can be distinguished by the complete propodeal carinae (at least anterior transverse carina absent in Gi. plana and Gi. nana ).
