Foretarsus 1.5 × as long as foretibia; hind femur only with ventral serrations; length of hind femur (without serrations) 3.7 × its maximum width; hind coxa sparsely punctate; hind femur largely rugose-punctate. First metasomal tergite about as long as its apical width; dorsal carinae in basal 0.4 of tergite; first tergite foveolate-reticulate; median length of second tergite 0.5 × its basal width, and as long as third tergite; second tergite punctatereticulate; third tergite smooth.

NOTES: W. sonla , sp. nov., runs to W. brevicarinata ( Yan and Chen, 2014) (couplet 14b) in the key by Yan et al. (2017), but differs as follows: (1) hind femur slenderer, length of hind femur 3.7 × as long as its maximum width (without serrations) (3.3 × in W. brevicarinata ); (2) vein r of forewing distinctly shorter vein 3-SR (vein r 1.3 × 3-SR × in W. brevicarinata ); and (3) antenna dark brown with segments 11–18 cream white (9–21 in W. brevicarinata ).
