Type material.

Holotype, female, Hongyangu, Wugongshan Natural Reserve, 530m, 24 May 2016, collected with IT by Yu Yao (GSFPM).

Diagnosis.

Subapical portion of clypeus strongly convex, forming a transverse ridge, apical margin without exceptional long hairs (Fig. 2). Area superomedia with dense, irregular transverse rugae (Fig. 11). Propodeal spiracle large, elongate, approximately 2 × as long as wide (Figs 7, 8). Second and subsequent tergites black (Fig. 1). Dorsal side of hind tibia darkish brown, ventral side yellow-brown (Fig. 9). First tergite dark brown, posterior portion of postpetiole red-brown. Second and subsequent tergites black.

Description.

Female. Body length approximately 8.5 mm. Forewing length approximately 6.0 mm. Ovipositor sheath length 1.2 mm. Head, mesosoma, and apical portion of metasoma with dense short yellowish brown hairs.

Head. With dense large punctures. Face 2.8 × as wide as long, strongly convex. Clypeus 4.0 × as wide as long (Fig. 2); basal portion with transverse rugae; subapical portion strongly convex, forming a transverse ridge. Basal portion of mandibles with longitudinal rugae and fine punctures; lower tooth 3.7 × as long as upper tooth. Eye particularly small, with sparse short hairs. Malar space 0.4 × as long as basal width of mandible. Gena in lateral view 1.4 × as long as width of eye, with punctures larger than those of face. Vertex (Fig. 3) with dense uneven puctures. Postocellar line 1.2 × as long as ocular-ocellar line. Antenna (Fig. 4) short, with 19 flagellomeres. Second flagellomere 1.25 × as long as maximum width. Ratio of length from first to fifth flagellomeres: 1.4:1.0:0.9:0.8:0.7. Occipital carina complete.

Mesosoma. Anterior portion of pronotum laterally (Fig. 5) with dense irregular rugae and punctures; lateral concavity with uneven transverse rugae; upper posterior portion with large punctures. Epomia distinct. Mesoscutum (Fig. 6) shiny, with irregular punctures, postero-median portion with longitudinal rugae. Scutellum (Fig. 6) slightly convex, smooth, shiny, with sparse punctures. Upper portion of mesopleuron (Fig. 7) with dense, irregular punctures, lower portion with transverse rugae and irregular, indistinct punctures; lower posterior portion with oblique rugae. Speculum small, smooth, shiny. Metapleuron (Fig. 8) with strong, irregular reticulate rugae. Wings gray, hyaline. Fore wing with vein 1cu-a distinctly distal of 1-M. Areolet pentagonal. Distance from vein 2rs-m to 2m-cu slightly longer than distance from 2m-cu to 3rs-m. Vein 2-Cu approximately 2 × as long as 2cu-a. Hind wing vein 1-cu about 3 × as long as cu-a; 1-cu strongly inclivous. Hind leg (Figs 9, 10) exceptionally stout. Hind femur 2.5 × as long as its maximum width. Ratio of length of one to fifth hind tarsomeres 2.0:1.0:0.7:0.4:1.0. Propodeum (Fig. 11) with complete carinae. Area basalis shiny, with sparse fine punctures, strongly convergent posteriorly. Area superomedia hexagonal, with strong irregular transverse rugae, costula connecting approximately at its posterior 0.3. Area petiolaris strongly slant, with irregular transverse rugae. Area externa shiny, with distinct, uneven punctures. Area dentipara and area lateralis with irregular reticulate rugae. Propodeal spiracle (Fig. 8) elongate, approximately twice as long as wide.

Metasoma. Tergites smooth, shiny. First tergite 1.7 × as long as posterior width, median dorsal carinae reaching about 0.6 of first tergite; posterolateral parts with sparse fine punctures. Dorsolateral and ventrolateral carinae complete. Spiracle circular, small, located at posterior 0.3 of first tergite. Second tergite 0.56 × as long as its posterior width, with a few indistinct fine punctures. Third tergite 0.7 × as long as its posterior width, 0.8 × as long as its posterior width. Fourth and subsequent tergites with short brown pubescence. Ovipositor sheath 0.9 × as long as hind tibia.

Coloration (Fig. 1). Black, except for the following. Clypeus, mandibles except teeth, reddish brown. Maxillary and labial palpi fawn. Ventral side of scape and pedicel reddish brown. Ventral side of flagellum slightly brownish. Flagellomeres 5 to 9 white, ventral side narrowly slightly blackish. Dorsal sides of legs red-brown, ventral sides yellow-brown; apical portion of hind tibia and tarsi more or less brownish black. Tegulae and posterior portion of postpetiole red-brown. First tergite dark brown. Pterostigma and veins brownish black.

Remarks.

This new species is similar to G. watanabei (Uchida, 1930) but can be distinguished from the latter by the following combination of characters: apical margin of clypeus without unusual long hairs (vs. with dense, long hairs; see Fig. 12). Area superomedia with strong irregular transverse rugae, costula connecting at its posterior 0.3 (vs. smooth, shiny, without rugae, costula connecting slightly beyond its middle; see Fig. 13). Ovipositor sheath 0.9 × as long as hind tibia (vs. 0.75). Clypeus entirely reddish brown (vs. basally black, apically brown). First tergite dark brown (vs. black). All coxae and hind femur yellow brown (vs. black). It can also be distinguished from the known species of the Oriental and Eastern Palaearctic Regions by the preceding key.

Etymology.

The specific name is derived from the type locality.
