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.......
