Diagnosis
Occipital carina widened medio-dorsally, with short carinae (Fig. 75); outer side of supra-antennal elevations subvertical and elevations about 0.7 times as long as scapus (Figs 75, 79); head dorsally coarsely reticulate-punctate (Fig. 75); apical half of supra-antennal elevations yellowish brown (Fig. 75); tyloids of male antenna elliptical and short (Fig. 77); basal half of metasoma largely smooth, apical half mainly punctate (Fig. 82); metasoma largely black pair of small lateral patches on first and second tergites, apical margin of first and second sternites (Figs 83, 84); first tergite about 0.7 times as long as its apical width (Fig. 84); second sternite simple (Fig. 84); third sternite about 0.2 times as long as second sternite (Fig. 84).
Description
Holotype, male, length of body 9.6 mm (of fore wing 7.7 mm).
Head. Antenna with 25 segments, tyloids circular, 0.5 times as long as segment on 11th–14th segments and 0.2 times as long as segments on 10th and 16th segments (Fig. 77); frons densely punctate; vertex spaced and finely punctate (interspaces much wider than width of punctures) (Fig. 75), with short setae; temple largely smooth with sparse fine punctures (Fig. 79); head gradually narrowed behind eyes, eye in dorsal view 1.2 times as long as temple (Fig. 75); occipital carina moderately widened and lamelliform medio-dorsally, with many short carinae; supra-antennal elevations strongly enlarged (about 0.7 times as long as scapus), outer side subvertical and largely smooth except for sparse punctures; clypeus slightly concave and thick medio-ventrally.
Mesosoma. Length of mesosoma 1.8 times its height (Fig. 81); mesopleuron below transverse mesopleural groove reticulate-rugose anteriorly and largely smooth with sparse fine punctures posteriorly, above groove similar (Fig. 81); transverse mesopleural groove narrow, deep and moderately crenulate; notauli narrow anteriorly, widened posteriorly and coarsely crenulate; mesoscutum densely and coarsely rugose, rugae on lateral lobes of mesoscutum less coarse (Fig. 80); scutellar sulcus wide, both medially and laterally and coarsely crenulate; scutellum densely and coarsely rugose, convex medially and anteriorly near level of mesoscutum; metanotum medially protruding, obtuse and densely and finely punctate (Fig. 81); propodeum rugulose anteriorly with smooth patches antero-laterally, transversely striate medio-posteriorly (Fig. 80); posterior propodeal carina thick lamelliform, foramen medially 0.6 times higher than wide basally.
Wings. Fore wing: length of vein 1-M 2.2 times as long as vein 1-SR (Fig. 78).
Metasoma. First tergite 0.8 times as long as apically wide, smooth and with distinct elliptical depression medially (Fig. 82); second tergite largely smooth with sparse fine punctures posteriorly, other tergites superficial coriaceous anteriorly, densely finely punctate posteriorly (Fig. 82); sternites densely and rather coarsely punctate; second sternite weakly curved in lateral view; third sternite about 0.4 times as long as second sternite (Fig. 84); genitalia extruded (Fig. 83).
Colour. Black; mandible largely except brown teeth, inner orbita narrowly, apical half of supra-antennal elevations, pair of wide patches of clypeus, malar space pair of narrow patches of middle lobe of mesoscutum antero-laterally, small medial patch of metanotum, pair of small lateral patches on first and second tergites, apical margin of first and second sternites, base of fore trochanter and trochantellus, fore and hind trochanters and trochantelli ivory (Figs 74, 75, 80, 83, 84); metasoma ventrally black; palpi and antenna dark brown; ivory, fore tarsi and tibia yellowish brown, remainder of legs dark brown to black; pterostigma and anterior half of marginal cell dark brown, remainder of wing membrane subhyaline.
Female. Unknown.
Biology
Unknown. Collected in August at 1800–2000 m.
Distribution
China (Sichuan).
Etymology
Named after the yellow supra-antennal protuberances: from “luteus” (Latin for “yellow”).
