Type material.

Holotype, ♀ (SCAU) "[China:] Guizhou, Mt. Fanjing, Huixiangping, 11.VII.1993, Zai-fu Xu, 936625".

Diagnosis.

Supra-antennal elevation 0.4 times as long as scapus and outer side of elevations oblique (Fig. 487) occipital carina widened medio-dorsally and crenulate (Fig. 487); head dorso-posteriorly densely punctate and entirely black (female) (Fig. 487); basal half of antenna (except scapus) yellowish brown (Fig. 488); mesosoma mainly or entirely orange-brown dorsally (Fig. 491) or black with extensive yellowish and orange pattern with middle mesoscutal lobe similar to lateral lobes (Fig. 491); notauli posteriorly and scutellar sulcus wide and both coarsely crenulate (Fig. 491); fore wing without subapical infuscation (Fig. 489); second sternite of female distinctly convex (Fig. 494).

Description.

Holotype, female, length of body 12.3 mm (of fore wing 11.1 mm).

Head. Antenna with 26 segments; frons coarsely reticulate-punctate (Fig. 486); vertex coarsely reticulate-punctate behind stemmaticum and near eyes, becoming spaced punctate (interspaces much wider than width of punctures) posteriorly (Fig. 487); temple reticulate-punctate dorsally, becoming spaced punctate ventrally; head gradually narrowed behind eyes, eye in dorsal view 1.2 times as long as temple (Fig. 487); occipital carina widened medio-dorsally and crenulate (Fig. 487); supra-antennal elevations medium-sized (about 0.4 times as long as scapus), outer side oblique and largely smooth except for sparse punctures; clypeus slightly concave and thick medio-ventrally.

Mesosoma. Length of mesosoma 1.4 times its height (Fig. 492); mesopleuron below transverse mesopleural groove transversely rugose anteriorly and smooth posteriorly, above groove entirely transversely rugose (Fig. 492); transverse mesopleural groove rather wide, deep and coarsely crenulate; notauli wide, deep and coarsely crenulate; middle lobe of mesoscutum coarsely reticulate-rugose, lateral lobe mainly rugose; scutellar sulcus wide, both medially and laterally and coarsely crenulate; scutellum coarsely reticulate-rugose, convex medially and anteriorly near level of mesoscutum; metanotum medially slightly convex, not protruding and rugose (Fig. 491); propodeum rugulose to smooth antero-laterally, transversely striate medially, irregularly rugulose posteriorly (Fig. 491); posterior propodeal carina thick lamelliform and slightly arched, foramen medially 0.4 times higher than wide basally.

Wings. Fore wing: length of vein 1-M twice as long as vein 1-SR (Fig. 489).

Metasoma. First tergite 0.6 times as long as apically wide, largely smooth and with distinct elliptical depression medially (Fig. 493); second tergite spaced and rather finely punctate, third–sixth tergites densely and coarsely punctate; first and second sternites spaced and rather finely punctate, third–fifth sternites densely and finely punctate; second sternite distinctly convex, without medio-apical protuberance (Fig. 494); third sternite about 0.1 times as long as second sternite (Fig. 495); hypopygium triangular in ventral view (Fig. 494).

Colour. Head black with pale yellow stripes along inner orbita and apex of supra-antennal elevations and dorsal-medial occipital carina brown; mesosoma orange-brown dorsally (Fig. 491); mesosoma largely orange-brown laterally except for anterior and dorsal yellow patches of pronotal side and dark brown propleuron; metasoma with moderately wide orange-yellow apical band at apex of first tergite and sternite, second tergite with broad orange-yellow band at posterior margin, remainder of metasoma black; palpi dark brown; mandible black with teeth dark brown; basal half of antenna (except scapus) yellowish brown, scapus and apical half of antenna dark brown (Fig. 488); trochanters and trochantelli and base of femora of all legs pale yellow, tibiae and tarsi of fore and mid leg yellowish brown, mid and hind coxae orange-brown, remainder of legs dark brown; pterostigma dark brown, remainder of wing membrane subhyaline.

Male. Unknown.

Distribution.

China (Guizhou).

Etymology.

Named after the coarsely sculptured notauli and scutellar sulcus: from “sculpturatus” (Latin for “sculptured”).
