Type material.

Holotype, ♀ (IZCAS) "[China:] Sichuan, Mt. Emei, Baoguosi, 550-750 m, 5.VII.1957, Ke-ren Huang, IOZ(E)1495445". Paratypes: 2 ♀ (IZCAS), same data as holotype, IOZ(E)1495246, IOZ(E)14952467; 1 ♀ (IZCAS) "[China:] Sichuan, Mt. Emei, Qingyingge, 800-1000 m, 11.VII.1957, You-cai Lu, IOZ(E)1495245".

Diagnosis.

Outer side of supra-antennal elevations oblique and elevations about 0.4 times as long as scapus (Fig. 584); occipital carina strongly widened medio-dorsally and distinctly lamelliform (Fig. 584); head posteriorly entirely black and dorsally punctate with distinct smooth interspaces (Fig. 584); middle mesoscutal lobe similarly coloured to lateral lobes, black or yellow laterally and black medially (Fig. 588); anterior half of fore wing membrane dark brown (Fig. 586); mesosoma entirely black (Fig. 590); second sternite of female distinctly convex (Fig. 591; probably less of ♂); third sternite of female with large hook-shaped protuberance (Fig. 591); metasoma with limited pale pattern (Fig. 590).

Description.

Holotype, female, length of body 14.2 mm (of fore wing 12.0 mm).

Head. Antenna with 25 segments; frons, vertex and temple coarsely reticulate-punctate (Figs 583, 584, 587); head gradually narrowed behind eyes, eye in dorsal view 0.7 times as long as temple (Fig. 584); occipital carina narrowly lamelliform and smooth medio-dorsally; supra-antennal elevations medium-sized (about 0.4 times as long as scapus), outer side oblique and rugulose; clypeus slightly concave and thick medio-ventrally.

Mesosoma. Length of mesosoma 1.4 times its height (Fig. 589); mesopleuron coarsely reticulate-punctate, above transverse mesopleural groove with large foveolae medio-dorsally; notauli moderately wide, deep and coarsely crenulate; mesoscutum coarsely reticulate-punctate (Fig. 588); scutellar sulcus complete, moderately wide and crenulate; scutellum coarsely reticulate-punctate, convex anteriorly and near level of mesoscutum, with a shallow furrow medially; metanotum medially slightly convex, not protruding and densely reticulate-punctate (Fig. 588); propodeum coarsely reticulate-rugose, rugae less coarse medially (Fig. 588); posterior propodeal carina thick lamelliform and slightly arched (about twice as wide as high medially).

Wings. Fore wing: length of vein 1-M 1.4 times as long as vein 1-SR (Fig. 586).

Metasoma. First tergite 0.7 times as long as apically wide, smooth and with distinct elliptical depression medially (Fig. 590); second–sixth tergites coarsely reticulate-rugose; sternites densely and coarsely punctate; second sternite distinctly convex in lateral view, its medio-apical protuberance small and acute medio-apically (Fig. 591); third sternite about 0.3 times as long as second sternite, with a large hook-shaped triangular protuberance medially (Figs 591, 592); hypopygium triangular in ventral view (Fig. 592).

Colour. Black; palpi dark brown; mandible dark brown; antenna dark brown; frons with narrow yellowish brown stripes along inter orbita, remainder of head black; tegulae dark brown; legs dark brown to black with tibia and tarsi paler; metasoma with moderate wide orange-brown apical band at apex of second tergite and sternite; pterostigma and anterior half of fore wing dark brown, ventral half subhyaline.

Variation. Length of body13.1-14.4 mm, of fore wing 10.0-12.0 mm; mandible black; length of vein 1-M of fore wing 1.3-1.5 times as long as vein 1-SR.

Male. Unknown.

Biology.

Unknown. Collected in July at 550-1000 m.

Distribution.

China (Sichuan).

Etymology.

Named after the hook-shaped protuberance of the third sternite: from “uncus” (Latin for “hook”) and “fera” (Latin suffix for "carry, have").
