Diagnostic characters. Antenna with 32 flagellomeres, 9 th –14 th flagellomeres cream white; frontal protuberance lamelliform, acute dorsally (Figs 4B, C); 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). 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); 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); 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, 4F) (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....... W. simulata Long, 2020
11a’. Frontal protuberance lamelliform, pointed apically (Figs 4B, C); propodeum with areola (11b); second submarginal cell of fore wing trapezium-shaped, broad (11 bb); vein r exiting from before middle of pterostigma; vein 3-SR 1.2 × r (11 bb); vein 1-M of hind wing 2.1 × as long as vein 1r-m (Fig. 4J).................................... W. robustifemur Long, sp. nov.
