Description.

Length of body 3.8 mm, fore wing 3.4 mm, and ovipositor sheath 5.5 mm.

Head (Figs 1 a–b, d): Antennae with 29 segments; first flagellomere parallel-sided, 3.1 times as long as its maximum width, 1.1 and 1.2 times as long as the second and third flagellomeres, respectively; second and third ones 2.8 and 2.9 times as long as their maximum width, respectively; median flagellomeres 2.6 times as long as their maximum width; terminal flagellomere tapering apically, approximately 2.9 times as long as its basal width; medio- transversal clypeal carina without a row sparse long setae; height of clypeus: inter-tentorial distance: tentorio-ocular distance = 1: 3: 5; malar space 0.35 times as long as height of eye; face with sparse long setae; height of face: width of face: width of head = 11: 13: 16; frons smooth and shiny, weakly impressed and without longitudinal ridge medially; shortest distance between posterior ocelli: diameter of posterior ocellus: shortest distance between posterior ocellus and eye = 2: 1: 7; vertex smooth and shiny, with sparse long setae medially.

Mesosoma (Fig. 1c): Mesosoma 1.8 times as long as its maximum height, smooth and shiny with sparse long setae mid-posteriorly; notauli deeply impressed anteriorly and shallow posteriorly with sparse short setae along its whole length; middle lobe of mesoscutum rather raised anteriorly and protruding in front of the lateral lobes; scutellar sulcus relatively wide and deep, distinctly crenulate; metanotum with a strongly raised area medially; propodeum glabrous, with a mid-longitudinal carina and sparse setae, relatively densely setose laterally.

Wing (Fig. 1e): Length of fore wing veins SR1: 3-SR: r = 38: 11: 7; vein 1-SR+M of fore wing weakly bent; length of fore wing veins 2-SR: 3-SR: r-m = 10: 11: 7; length of veins of hind wing SC+R1: 2-SC+R: 1r-m = 12: 4: 5; vein 2-SR+R of hind wing distinctly longitudinal; vein C+SC+R of hind wing with short thickened humeral bristles apically.

Leg: Length of fore femur: tibia: tarsus = 23: 26: 34; length of hind femur: tibia: basitarsus = 25: 43: 9, and 3.9, 10.0 and 8.0 times their maximum width, respectively; tibia of hind leg with weakly longitudinal groove medially; spurs of hind leg 0.35 and 3.1 times as long as its basitarsus; tarsal claws simple but with basal lobe.

Metasoma (Figs 1f, g): Metasoma distinctly longer than head and mesosoma combined, more or less parallel-sided; first tergite 1.3 times as long as its maximum apical width, with strongly raised area medio-apically and crenulate laterally, occupying four-fifths of its entire length; second tergite with medio-basal glabrous band reaching the suture between second and third tergites, and lateral depressed longitudinal grooves crenulate laterally, the remainder with rugulose sculpture; suture between second and third tergites deep and crenulate, wide medially and narrowed laterally; third tergite with distinct raised areas antero-laterally, smooth and shiny, with sparse setae apically; fourth-seventh tergites uniformly smooth and shiny, with sparse short setae apically; hypopygium acute apically, distinctly extending beyond apex of metasoma; ovipositor sheath 1.6 times as long as fore wing, with dense setae; ovipositor with teeth apico-ventrally and without dorsal notch pre-apically.

Colour:

Head dark yellow; antenna yellowish brown; face dark yellow; frons and vertex brown; mesosoma black; fore leg pale yellow, middle and hind legs dark yellow; pterostima yellowish brown; wings membrane pale grey, and veins dark yellow; metasomal tergites yellowish brown dorsally and pale yellow ventrally; ovipositor sheath yellowish brown.

Male:

Similar to the female, but relatively small, length of body 3.5 mm, metasoma black.

Biology:

Unknown.

Distribution:

China (Henan).

Etymology:

The new species is named after the type locality, Jigongshan in Henan (Central China).

Diagnosis:

This species is similar to Dolabraulax implicatus Quicke, but differs from the latter by the characters listed in the key above.
