BIOLOGY: Unknown.  
 DIAGNOSIS: Antenna with 41 segments; antennal segments 12–23 cream white; maxillary palp 1.7 × as long as head; in frontal view width of face 1.8 × length of face and clypeus combined; frontal protuberance with distinct ledge halfway and blunt dorsally; in dorsal view width of head 1.4 × its median length; height of eye 1.5 × as long as temple; in lateral view height of eye 1.4 × as long as its transverse width; transverse width of eye 1.4 × temple. Mesosoma 2.4 × as long as high; notauli crenulated anteriorly, fused with coarsely rugose area posteriorly; scutellar sulcus 0.5 × as long as scutellum; propodeum with basal median carinae and narrow areola; propodeum almost areolate-rugulose. Length of forewing 3.5 × its maximum width; vein 3-SR 2.0 × vein r; vein 2-M 2.0 × as long as vein 3-SR; hind wing vein 1-M 0.5 × vein 1r-m; vein 2-SC+R long, 0.3 × as long as vein 1r-m; hind wing with 5 hamuli. Foretarsus 1.5 × longer than foretibia; hind femur with ventral serrations and stout protuberance; length of hind femur (without protuberance or serrations) 4.4 × its maximum width; hind coxa sparsely punctate; hind femur largely rugose-punctate. First metasomal tergite 1.8 × as long as its apical width; dorsal carinae in basal 0.6 of tergite; first tergite smooth basally and apically, punctate laterally, punctate-reticulate medially between dorsal carinae; median length of second tergite 0.7 × its basal width, and as long as third tergite; second suture distinct; second tergite smooth with sparse punctures laterobasally; third tergite smooth.   
 NOTES: W. similis, sp. nov., runs to W. eurygenys Yan and Chen, 2017, from China in couplet 3b of the key by Yan et al. (2017), but differs as follows: (1) first metasomal tergite 1.8 × as long as apical width (1.4 × in W. eurygenys); (2) scapus densely setose ventrally (scapus with few medium-sized setae in W. eurygenys); (3) vein r of forewing 0.5 × vein 3-SR (0.8 × in W. eurygenys); (4) vein 1-M of hind wing 0.5 × vein 1r-m (0.7 × in W. eurygenys) and (5) antennal segments 12–23 cream white (13–18 in W. eurygenys).
