Description. Female (n=3). Body polished, covered with silver setae, length 7.5–8.0 (HT: 8.0) mm.
Head 0.55 × as long as wide. Clypeus sparsely punctate dorsally, smooth ventrally, 0.5–0.54 (HT: 0.5) × as long as maximum wide, convex in lateral view, its apical margin rounded, without a median tooth or convexity, narrowly impressed. Face 0.45–0.48 (HT: 0.45) × as long as maximum wide, punctate except for rugae around antennal sockets, weakly convex medially. Frons concave above antennal sockets, largely rugose anterior to ocelli, with smooth areas above antennal sockets, without a median longitudinal carina. Apical margin of labrum subtruncate. Antennal socket more or less raised. Length of malar space 0.75–0.8 (HT: 0.75) × as long as basal mandibular width. Mandible weakly convex basally, with a narrow ventral flange. Upper tooth of mandible almost as long as lower tooth. OD: POL: OOL = 1.0: 1.5–1.6 (HT: 1.5): 1.4–1.5 (HT: 1.5). Flagellum with 24–25 (HT: 25) segments. FL I 5.0–6.0 (HT: 6.0) × as long as maximum depth in lateral view and 1.1 × as long as FL II.
Mesosoma. Lateral aspect of pronotum smooth dorsally, longitudinally strigose ventrally, dorsal margin with a longitudinal convexity (Fig. 9D). Epomia present, its lower end far distant from anterior margin of pronotum. Posterior end of notauli reached to posterior end of mesoscutum. Mesoscutum densely punctate, with some longitudinal rugae on posterior part of median lobe (Fig. 9D). Scutellum smooth with a few punctures. Mesopleuron largely rugose, with a smooth area on speculum. Mesosternum with a median part of posterior transverse carina. Metapleuron reticulate rugose with complete juxtacoxal carina. Propodeum reticulate rugose, with a pair of sublateral apophyses (Fig. 9E). Anterior section of lateromedian longitudinal carina present. Anterior transverse carina complete. Posterior transverse carina and pleural carina absent. Propodeal spiracle oval. Area basalis widened anteriorly. Fore wing length 5.6–6.3 (HT: 6.3) mm. Areolet pentagonal, longer than wide, small, vein 2rs-m and vein 3rs-m subparallel or slightly convergent anteriorly (Fig. 9B). Nervellus of hind wing intercepted below the middle by second abscissa of vein Cu (Fig. 9B). Hind femur 5.0 × as long as maximum depth in lateral view. Hind TS I: II: III: IV: V = 4.8–5.0 (HT: 5.0): 2.0: 1.2: 0.6–0.7 (HT: 0.6): 1.5–1.6 (HT: 1.6).
Metasoma polished. T I 1.5 × as long as maximum width, punctate, with latero-median carina in part, with complete dorso-lateral carina, with a pair of triangular teeth at base. T II 0.8–0.85 (HT: 0.8) × as long as maximum width. T II, T III and T IV densely punctate. Ovipositor sheath 0.75–0.78 (HT: 0.75) × as long as hind tibia. Apex of ovipositor as Fig. 3E.
Colouration (Figs 9 A-E). Body (excluding wings and legs) black to blackish brown, except for: a median spot of face, mandible and a pair of spots on vertex along inner margin tinged with yellowish brown; FL VII to IX or to FL X white except for outer surface; palpi yellowish brown; a large dorsal stripe of pronotum, a small ventral spot of pronotum, scutellum, anterior part of tegula, humeral plate, a small spot of subtegular ridge, upper division of metaopleuron, a pair of longitudinal spots (its anterior end situated near apophysis) of propodeum and posterior margin of T I and T II whitish yellow to yellow; a pair of spots on posterior margin of T IV to T VII white to whitish yellow; ovipositor dark reddish brown. Wings hyaline. Veins and pterostigma blackish brown to brown. Legs black to blackish brown, except for: fore and mid coxae each with a whitish yellow to yellow spot; trochanters and trochantelli partly tinged with yellowish brown to reddish brown; fore and mid femora, tibiae and tarsi largely reddish brown to yellowish brown; base of hind femur narrowly tinged with reddish brown; hind TS II and TS III whitish yellow except for apex. Yellow area of face sometimes indistinct. Clypeus sometimes tinged with reddish brown. Base of hind tibia sometimes tinged with reddish brown.
Male. Unknown.
Distribution. Japan (Honshu).
Etymology. The species name is from the beautiful and elegant colouration of this species.
Remarks. This species resembles Go. interrupta in the character states of frons, pronotum and areolet and the coloration, but it can be distinguished by the flagellum with 24–25 segments (28 segments in Go. interrupta), the collar black (yellow in Go. interrupta), the hind coxa and femur black (largely reddish brown in Go. interrupta) and the ovipositor sheath 0.75–0.78 × as long as hind tibia (0.63 in Go. interrupta).
