Diagnostic characters. Antenna with 32 flagellomeres, 9 th –14 th flagellomeres cream white; frontal protuberance lamelliform, acute dorsally ( Figs 4B, C View FIGURE 4 ); in dorsal view width of head 1.75 × its median length; height of eye 2.2 × temple; in frontal view height of eye 1.9 × its transverse width; width of face 1.65 × length of face and clypeus combined; malar space 1.3 × height of eye; in lateral view height of eye 1.5 × as long as transverse width; transverse width of eye 1.6 × temple. Mesosoma 1.9 × longer than high; in lateral view, mesoscutum perpendicularly raised above pronotum; notauli deep, sparsely crenulate anteriorly, fused posteriorly with two rugosities forming one median carina close to scutellar sulcus; scutellar sulcus 0.6 × scutellum; propodeum with medio-basal carina and elongate areola ( Fig. 4G View FIGURE 4 ). Length of fore wing 2.9 × its maximum width; vein 3-SR 1.2 × r; vein 2-M 2.0 × 3-SR; hind wing vein 1-M 2.1 × 1r-m; vein 2-SC+R vertical. Fore tarsus 1.4 × as long as fore tibia; hind femur robust, with ventral serrations and without tooth-shaped protuberance ( Fig. 4K View FIGURE 4 ); length of hind femur (without tooth or serrations) 3.2 × as long as its maximum width; hind coxa smooth laterally, with sparse fine punctures and short sparse setae. First metasomal tergite slightly widened apically, 1.2 × longer than its apical width; dorsal carinae in basal 0.5 of tergite; first tergite areolate-rugulose medially; median length of second tergite 0.4 × its apical width ( Fig. 4H View FIGURE 4 ); second tergite largely punctate, 0.8 × as long as third tergite; first tergite areolate-rugulose; second tergite punctate-reticulate medially, smooth laterally and apically; the remaining tergites shiny, smooth.
Notes. W. robustifemur sp. nov. is similar to W. simulata Long, 2020 , but differs from the latter by the following characters: 1) in lateral view, mesoscutum vertically elevated above pronotum ( Figs 3 View FIGURE 3 , 4F View FIGURE 4 ) (mesoscutum roundly elevated above pronotum in W. simulata ); 2) dorsal carinae of first tergite in basal 0.5 of the tergite (vs 0.8 of the tergite); and 3) propodeum yellow entirely (vs propodeum black in W. simulata ).
W. robustifemur sp. nov. runs out to couplet 11a of the key by Long et al. (2020) as follows:
11a. Frontal protuberance lamelliform, not pointed apically; propodeum areolate-rugose, without areola (11a); second submarginal cell of fore wing trapezium-shaped, narrow (11 aa); vein r of fore wing exiting from middle of pterostigma; vein 3-SR 0.9 × r (11 aa) (see Fig. 102 in Long et al. 2020); vein 1-M of hind wing 0.4 × as long as vein 1r-m.......
