Diagnosis.

Antenna without ivory band subapically (Fig. 607); occipital carina weakly developed and smooth dorsally (Fig. 606); frons strongly shiny and smooth (Fig. 605); scutellum largely smooth, with longitudinal depression and strongly shiny (Fig. 610); mesosoma without pale pattern dorsally, mesoscutum black medially (Fig. 610); third submarginal cell 0.4-0.5 times as long as second submarginal cell; first tergite metasomal black, largely brownish-white or with a reddish-yellow lateral patch apically (Fig. 612); second tergite usually with ivory patch laterally (Fig. 612).

Description.

Holotype, female, length of body 7.5 mm (of fore wing 6.8 mm).

Head. Antenna with 20 segments; frons, vertex and temple smooth and shiny (Figs 605, 606, 609); head gradually narrowed behind eyes, eye in dorsal view 1.2 times as long as temple (Fig. 606); occipital carina weakly developed and smooth dorsally (Fig. 606); supra-antennal elevations medium-sized (about 0.4 times as long as scapus), outer side subvertical and obliquely and weakly striate (Fig. 606); clypeus hardly concave and very thick medio-ventrally.

Mesosoma. Length of mesosoma 1.4 times its height (Fig. 611); mesopleuron below transverse mesopleural groove coarsely rugose antero-dorsally and smooth ventrally and posteriorly, above groove coarsely rugose anteriorly and smooth posteriorly; transverse mesopleural groove wide, deep and coarsely crenulate; notauli moderately wide, deep and coarsely crenulate; mesoscutum smooth and strongly shiny, lateral lobe with a narrow and shallow mid-longitudinal furrow (Fig. 610); scutellar sulcus wide, both medially and laterally and coarsely crenulate; scutellum largely smooth, with longitudinal depression and strongly shiny, anteriorly near level of scutellum (Fig. 610); metanotum medially slightly convex, not protruding and smooth (Fig. 610); propodeum irregularly areolate (Fig. 610); posterior propodeal carina thick lamelliform and strongly arched, foramen medially 0.7 times higher than wide basally.

Wings. Fore wing: length of vein 1-M 2.8 times as long as vein 1-SR (Fig. 608).

Metasoma. First tergite 0.4 times as long as apically wide, smooth and with shallow depression antero-medially (Fig. 612); other tergites and sternites smooth to superficially coriaceous and shiny (Figs 612, 614); third sternite about 0.3 times as long as second sternite (Fig. 614); hypopygium triangular in ventral view.

Colour. Head black with short ivory stripes along inner orbita; mesosoma black except for middle lobe with central ivory patch posteriorly; metasoma largely black with large ivory spots on postero-lateral margin of second tergite and sternite; palpi dark brown; mandible black; antenna black; apex of fore femur, tibia and tarsus yellowish brown, outer side of hind coxa, hind trochanter and trochantellus ivory, remainder of legs dark brown to black; pterostigma of fore wing dark brown, remainder of wing membrane subhyaline.

Variation. Length of body 7.0-8.2 mm, of fore wing 5.7-7.0 mm; frons entirely black or with very faint ivory stripes; mesosoma entirely black or with faint and small central ivory patch; ivory spots on second tergite very small and absent on second sternite; outer surface of hind coxa black and all legs darker; length of vein 1-M of fore wing 2.8-3.2 times as long as vein 1-SR.

Male. Length of body 8.0-10.2 mm, of fore wing 6.7-8.1 mm; antenna with 20 segments; genitalia extruded (Fig. 616); otherwise similar to female.

Biology.

Unknown. Collected in July at 1400-1509 m.

Distribution.

China (Ningxia, Henan, Zhejiang, Sichuan).

Etymology.

Named after the largely smooth and shiny frons and scutellum: from “glaber” (Latin for "hairless, bald, smooth").
