Description.
Length of body 3.0-4.5 mm, fore wing 3.5-4.0 mm, and ovipositor sheath 5.0-5.5 mm.
Head (Figs 3 a–b , d): Antennae with 27 segments; first flagellomere parallel-sided, 3.0 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 2.5 and 2.7 times as long as their maximum width, respectively; median flagellomeres 2.6 times as long as their maximum width; terminal flagellomere tapering apically, approximately 3.4 times as long as its basal width; medio-transversal clypeal carina without a row sparse short setae; height of clypeus: inter-tentorial distance: tentorio-ocular distance =2.5: 6: 4; malar space 0.36 times as long as height of eye; face with sparse long setae, relatively dense laterally; height of face: width of face: width of head = 10: 11: 23; frons smooth and shiny, weakly impressed, without longitudinal ridge medially; shortest distance between posterior ocelli: diameter of posterior ocellus: shortest distance between posterior ocellus and eye = 2.5: 1: 7; vertex smooth and shiny, with sparse long setae laterally.
Mesosoma (Fig. 3c): Mesosoma 1.8 times as long as its maximum height, smooth and shiny with dense long setae medio-posteriorly; notauli shallowly impressed half of the anterior and flat posteriorly with sparse long setae along its whole length; middle lobe of mesoscutum relatively raised anteriorlly and protruding in front of the lateral lobes; scutellar sulcus rather wide and deep, with distinctly crenulate; metanotum with a strongly raised area medially; propodeum glabrous, with a mid-longitudinal carina, arising from the 1/4 of the hind margin, with sparse setae medially, but relatively densely long setose laterally.
Wing (Fig. 3f): vein r of fore wing relatively short, length of fore wing veins SR1: 3-SR: r = 37: 11: 6; vein 1-SR+M of fore wing weakly bent apically; length of fore wing veins 2-SR: 3-SR: r-m = 12: 11: 6; length of veins of hind wing SC+R1: 2-SC+R: 1r-m = 15: 3.5: 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 = 21: 23: 29; length of hind femur: tibia: basitarsus = 12: 11: 6, and 4.1, 10.0 and 7.5 times their maximum width, respectively; tibia of hind leg with weakly longitudinal groove medially; spurs of hind leg 0.36 and 3.3 times as long as its basitarsus; tarsal claws simple but with basal lobe.
Metasoma (Figs 3e, 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, crenulate laterally, occupying four-fifths of its entire length; second tergite with medio-basal glabrous band hardly 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 relative narrow laterally; third tergite with distinct raised areas antero-laterally, smooth and shiny, with sparse setae apically; fourth tergite without transversal impressed groove basally; fourth-seventh tergites uniformly smooth and shiny, with sparse short setae apically; hypopygium acute apically, distinctly extending beyond apex of metasoma; ovipositor sheath 1.8 times as long as fore wing, with dense setae; ovipositor with teeth apico-ventrally and without dorsal notch pre-apically.
Colour:
Head reddish yellow; antenna dark yellow; face reddish yellow; frons and vertex yellowish brown; mesosoma dark brown; 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 apically and ventrally; ovipositor sheath yellow brown.
Male:
Similar to the female, but relatively small, length of body 3.2 mm, metasoma dark yellow.
Biology:
Unknown.
Distribution:
China (Zhejiang).
Etymology:
The new species is named after the character of vein r of fore wing, which is relatively shorter.
Diagnosis:
This species is similar to Dolabraulax implicatus Quicke, but differs from the latter by characters listed in the key above.
