Type material.

Holotype, ♂ (ZJUH) "[China:] Tibet, Ranwu–Chayu, 22.VI.2009, Jiang-li Tan, 200906372".

Diagnosis.

Supra-antennal elevations 0.5-0.7 times as long as scapus and outer side of elevations often subvertical, smooth, strongly shiny and only apically ivory (Fig. 55); tyloids of male antenna nearly circular or short elliptical (Fig. 56); occipital carina extensively crenulate dorsally and widened (Fig. 55); third submarginal cell of fore wing about 0.4 times as long as second submarginal cell; first discal cell of fore wing less elongate (Fig. 57); first metasomal tergite about as long as its apical width (Fig. 61); third sternite 0.6-0.7 times as long as second sternite (Fig. 61); metasoma of male largely smooth and entirely black, slender (Fig. 61).

Description.

Holotype, male, length of body 9.3 mm (of fore wing 7.2 mm).

Head. Antenna incomplete, tyloids nearly circular, 0.1 times as long as segment on 10th segment and 0.2 times as long as segments on 11th -15th segments (Fig. 56); frons rugose (Fig. 54); vertex and temple largely smooth and shiny with sparse and fine punctures (Figs 55, 58); head gradually narrowed behind eyes, eye in dorsal view 0.9 times as long as temple (Fig. 55); occipital carina strongly widened and lamelliform, extensively crenulate dorsally; 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 1.6 times its height (Fig. 60); mesopleuron transversely reticulate-rugose anteriorly and smooth posteriorly (Fig. 60); transverse mesopleural groove moderately wide, shallow but distinctly crenulate; notauli moderately wide, deep and coarsely crenulate; middle lobe of mesoscutum somewhat transversely rugose, lateral lobes of mesoscutum mainly finely rugose with a shallow furrow medially (Fig. 59); scutellar sulcus wide, both medially and laterally and coarsely crenulate; scutellum densely and coarsely rugose, slightly convex medially and anteriorly near level of mesoscutum; metanotum medially protruding, obtuse and densely and finely punctate (Fig. 59); propodeum obliquely rugulose antero-laterally, transversely striate medially and irregular rugose posteriorly (Fig. 59); posterior propodeal carina thick lamelliform, foramen medially 0.7 times higher than wide basally.

Wings. Fore wing: length of vein 1-M 1.6 times as long as vein 1-SR (Fig. 57).

Metasoma. First tergite 1.1 times as long as apically wide, smooth and with distinct elliptical depression antero-medially, slightly convex posteriorly (Fig. 61); second–fifth tergites and all sternites largely smooth except for sparse superficial punctures (Fig. 61); second sternite rather flat; third sternite about 0.7 times as long as second sternite (Fig. 63); genitalia extruded (Fig. 62).

Colour. Black; inner orbita narrowly, apex of supra-antennal elevation and malar space ivory (Fig. 54); mandibular teeth, palpi and tegulae dark brown; tibiae and tarsi rather brownish; pterostigma and apical half of first submarginal cell to anterior half of marginal cell of fore wing and area below that dark brown, remainder of wing membrane subhyaline.

Female. Unknown.
