(Standard Japanese name: Oo-tsuya-togarihimebachi)
Type series. Holotype: JAPAN, KPM-NK 75742 , F, Fukui Pref., Imajo Town, Hachibuseyama , 21. VI. 1981, T. Murota leg. Paratype: KPM-NK 75743 , F, JAPAN, Fukui Pref., Oono City , 17. X. 1982, H. Kurokawa leg.
Description. Female (n=2). Body covered with silver setae, length 7.1–7.3 (HT: 7.1) mm.
Head 0.59–0.63 (HT: 0.59) × as long as wide, polished, finely and sparsely punctate. Clypeus 0.5 × as long as maximum wide, convex in lateral view, its apical margin rounded with a pair of lateral narrow impressions. Face 0.48–0.53 (HT: 0.48) × as long as maximum wide, slightly convex medially in lateral view. Frons with a smooth area above antennal sockets. Gena with a large smooth area. Length of malar space 0.65–0.7 (HT: 0.65) × as long as basal mandibular width. Base of mandible almost flat. 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 26 segments. FL I 6.0–6.67 (HT: 6.67) × as long as maximum depth in lateral view and 1.1–1.15 (HT: 1.15) × as long as FL II.
Mesosoma polished. Lateral aspect of pronotum punctate dorsally except for a large smooth area, longitudinally strigose ventrally ( Figs 8C, D View Fig ). Epomia present but weak. Posterior end of notauli reached to 0.8 of mesoscutum ( Fig. 8B View Fig ). Mesoscutum largely smooth ( Fig. 8B View Fig ) except for anterior part of median lobe densely punctate. Scutellum smooth with a few punctures. Mesopleuron largely punctate and rugose, with a smooth area on speculum ( Figs 8C, D View Fig ). Mesosternum with the short median portion of posterior transverse carina. Metapleuron punctate with a complete juxtacoxal carina. Propodeum punctate on area externa, area postero and area postero-externa and longitudinally rugose on area superomedia and area dentipara ( Fig. 8F View Fig ). Anterior section of lateromedian longitudinal carina present. Anterior transverse carina complete ( Fig. 8F View Fig ). Posterior transverse carina complete. Pleural carina absent except anterior section. Propodeal spiracle round. Area basalis widened anteriorly. Fore wing length 5.4–5.7 (HT: 5.7) mm. Areolet pentagonal, vein 2rs-m and vein 3rs-m convergent anteriorly ( Fig. 8G View Fig ). Nervellus of hind wing intercepted below the middle by second abscissa of vein Cu ( Fig. 8D View Fig ). Hind femur 4.6–4.8 (HT: 4.8) × as long as maximum depth in lateral view. Hind TS I: II: III: IV: V = 5.1: 2.0: 1.3: 0.7: 1.0.
Metasoma weakly polished. T I 1.8 × as long as maximum width, largely smooth, with a few, sparse punctures, without latero-median carina and dorso-lateral carina, with a pair of triangular teeth at base ( Fig. 2E View Fig ). T II 0.9–1.0 (HT: 0.9) × as long as maximum width, densely and finely punctate. T III and T IV granulate, covered with fine punctures. Ovipositor sheath 0.88–0.9 (HT: 0.88) × as long as hind tibia. Apex of ovipositor as Fig. 3E View Fig .
Colouration ( Figs 8 View Fig A-G). Body (excluding wings and legs) black to blackish brown, except for: malar space, mandible, base of FL I, subtegular ridge tinged with yellowish brown to yellow; FL 7 to FL 11 or to FL 12 except for ventral surface white; a pair of yellow spots of frontal orbit, palpi, tegula, humeral plate, membranous part of T VII and T VIII and membranous part of metasomal sternites whitish yellow; ovipositor reddish brown. Wings hyaline. Veins and pterostigma blackish brown to brown. Legs black to blackish brown, except for: fore and mid coxae each with whitish yellow area; trochanters except for base of hind trochanter white to whitish yellow; mid and hind tibial spurs whitish yellow; fore and mid legs except for coxae, trochanters and mid tibial spurs yellowish brown to reddish brown; hind trochantellus partly brown; base of hind tibia, base of hind TS I and TS III, TS II and apex of TS IV whitish yellow. Size of yellow area(s) on frons, malar space, mandible, subtegular ridge and coxae vary in size. Apex of scutellum sometimes narrowly tinged with yellow. Anterior part of tegula sometimes darkened. Hind coxa sometimes with a yellow spot dorsally. Posterolateral corner of T I and T II sometimes narrowly tinged with yellowish brown.
Male. Unknown.
Distribution. Japan (Honshu).
Etymology. The species name is from Japan.
Remarks. This species resembles Gl. varibalteatum Jonathan, 2000 in T I with a pair of triangle teeth basally and T II and T III covered with punctures, but it can be distinguished by the entirely black face (largely yellow in Gl. varibalteatum ) and the ovipositor sheath 0.85 × as long as hind tibia (ca. 0.7 in Gl. varibalteatum ). This species also can easily be distinguished by other Japanese species, Gl. acroclitae and Gl. simile , by the T I with a pair of triangle teeth basally, the metasomal tergites without yellow posterior band and the T II clearly and densely punctate.
