Head. Antenna (except scapus and pedicellus) missing; length of maxillary palp 1.9 times height of head; head 0.9 times as long as wide in frontal view; length of eye 1.5 times temple in dorsal view; length of malar space 0.8 times basal width of mandible and 0.25 times maximum width of eye; malar suture complete and deep; POL:OD:OOL = 12:10:25; vertex sparsely punctate and shiny; temple smooth and shiny dorsally, sparsely punctate ventrally, but rugose near mandible; occipital carina complete and distinct; frons crest-shaped elevated and punctate latero-posteriorly, rugose-crenulate latero-anteriorly, medio-posteriorly smooth, medio-anteriorly coarsely striate and with a strongly protruding lamella; face rugose-reticulate; clypeus weakly convex and rugose, ventrally smooth.

Mesosoma. Twice as long as high; pronope deep and wide; side of pronotum medially coarsely crenulate, subdorsally densely punctate, remainder reticulate-punctate; notauli narrow and deep, crenulate, coarsely rugosepunctate posteriorly; scutellum convex, punctate and with several striae posteriorly; prepectal carina complete and distinct; precoxal sulcus indistinct and punctate medially; mesoscutum punctate; scutellar sulcus with one carina and several lateral crenulae; metanotum with a complete median carina; propodeum rugose-punctate, with a transverse carina and a medio-longitudinal carina.

Wings. Fore wing: 3.5 times as long as wide; 1-M curved; pterostigma 3.7 times as long as wide; r:3-SR:SR1 = 10:20:81; 2-SR:3-SR:r-m = 20:20:14; 1-M:m-cu = 30:12; SR1 straight; cu-a inclivous, postfurcal; 1-CU1 short; rm inclivous. Hind wing: 1-M:1r-m = 17:27; cu-a inclivous.

Legs. Length of fore tarsus 1.4 times fore tibia; length of femur, tibia and basitarsus of hind leg 4.8 (excluding tooth), 9.4 and 8.5 times their width, respectively; length of outer and inner hind tibia spur both 0.26 times basitarsus; hind femur robust, ventrally largely transversely rugose (serrate in lateral view: Fig. 22 E) and with a small tooth.

Metasoma. First tergite widened posteriorly, reticulate-punctate, its dorsal carinae distinct and complete; length of first tergite 1.3 times its apical width; second tergite antero-medially smooth, postero-laterally rugosepunctate and remainder coarsely punctate, about twice as wide as long; ovipositor sheath twice as long as metasoma, 1.8 times as long as hind tibia and 0.9 times as long as fore wing.

Colour. Black; palpi yellow and transparent; first metasomal sternite, fore and middle legs, hind coxa, trochanter, trochantellus, basal one-third of hind femur, hind femur ventrally and basal 2/3 of hind tibia yellow; hind tarsus whitish yellow; clypeus, basal of mandible, three basal antennal segments dark reddish brown; apical third of hind tibia reddish brown; tegulum, pterostigma and most veins dark brown; wing membrane slightly infuscate.

Male. Unknown.

Material examined. Holotype: 1♀, China, Yunnan prov., Southeast Pingbian, Dawei Mt., 1300 m, 17.VI.1956, Bangfeiluofu, No. IOZ(E)1689943 (IZAS).

Comparative diagnosis. This new species is similar to W. atkinsoni Gupta et Sharma, 1976, but differs in having the length of malar space 0.8 times basal width of mandible (twice basal width of mandible in W. atkinsoni); dorsal carinae of first tergite distinct and complete (dorsal carinae only distinct on basal quarter) and second tergite antero-medially smooth, postero-laterally rugose-punctate, remainder coarsely punctate (only medially punctate and remainder smooth).

Host. Unknown.

Etymology. It is named after its partly rugose second tergite.

Distribution. China (Yunnan).
