DISTRIBUTION: NW Vietnam: Son La (Thuan Chau).
BIOLOGY: Unknown.
DIAGNOSIS: Antenna with 31 segments; antennal segments 3–19 pale yellow; maxillary palp 1.75 × as long as head; in frontal view width of face 1.8 × length of face and clypeus combined; frontal protuberance robust, higher than lateral frontal carina; in dorsal view width of head 1.5 × its median length; height of eye 1.9 × temple; in lateral view height of eye 1.3 × its transverse width; transverse width of eye 1.7 × temple; face coarsely rugose; frons, vertex, and temple mat. Mesosoma 2.3 × as long as high; notauli narrow, sparsely crenulate, fused posteriorly with median carina in rather flat posterior area of mesoscutum; scutellar sulcus 0.5 × as long as scutellum; propodeum with basal carina and areola; propodeal areola mat; propodeum transversely rugose laterally. Length of forewing 3.3 × its maximum width; vein 3-SR 1.45 × as long as vein r; vein 2-M 2.1 × 3-SR; hind wing vein 1-M 0.7 × vein 1r-m; vein 2-SC+R transverse, 0.2 × vein 1r-m. Foretarsus 1.65 × as long as foretibia; hind femur with ventral serrations and acute tooth-shaped protuberance; hind femur (without tooth or serrations) 3.8 × as long as its maximum width and rugose-punctate. First metasomal tergite 1.8 × its apical width; dorsal carinae in basal 0.6 of tergite; first tergite largely smooth, except sparsely punctate-reticulate medioapical area; median length of second tergite 0.9 × its apical width, and 1.25 × third tergite; second and third tergites smooth.
NOTES: W. plana , sp. nov., runs to W. eurygenys Yan and Chen, 2017 , from China in the key by Yan et al. (2017), but differs as follows: (1) in dorsal view length of eye 1.9 × as long as temple (1.2 × in W. eurygenys ); (2) first metasomal tergite 1.8 × as long as its apical width (1.4 × in W. eurygenys ); and (3) hind coxa and femur yellow and only infuscate apically (reddish brown in W. eurygenys ).

ETYMOLOGY: From planus (Latin for “even, flat”), because of the flat mesopleuron.
