NOTES: W. simulata , sp. nov. , runs to W. zhejiangensis Yan and van Achterberg, 2017 , from China in couplet 10a of the key by Yan et al. (2017) , but differs as follows: (1) frontal protuberance narrowed from base to apex, blunt apically (with posterior protruding narrow lamella in W. zhejiangensis ); (2) foretarsus 1.65 × as long as foretibia (1.1 × in W. zhejiangensis ); (3) first metasomal tergite 1.3 × as long as apical width (1.1 × in W. zhejiangensis ) and (4) antenna with 8 (11th–18th) cream white segments (6 [13th–18th] in W. zhejiangensis ). The new species is also similar to W. albobasalis van Achterberg and Chen, 2017 , from China , but differs as follows: (1) frontal protuberance acute (triangular in W. albobasalis ); (2) hind femur more slender, 3.5 × longer than its maximum width (2.8 × in W. albobasalis ); (3) vein 1-M of hind wing 0.7 × vein 1r-m (0.4 × in W. albobasalis ); and (4) antenna dark brown with segments 11–20 cream white (3rd–11th in W. albobasalis ).
