Mesosoma 2.3 × longer than high; in lateral view, mesoscutum perpendicularly raised above pronotum; notauli wide, sparsely crenulate anteriorly, fused posteriorly with one median rugosity in areolate-rugose area of mesoscutum ( Fig. 2E View FIGURE 2 ); scutellar sulcus 0.8 × scutellum; propodeum with medio-basal carina and trace of round areola, largely rugose. Length of fore wing 3.3 × its maximum width; vein 3-SR 1.1 × as long as r; vein 2-M 2.2 × 3-SR; hind wing vein 1-M 0.7 × 1r-m; vein 2-SC+R vertical. Fore tarsus 1.3 × as long as fore tibia; hind femur comparatively robust, with ventral serrations and without stout tooth-shaped protuberance; length of hind femur (without tooth or serrations) 3.05 × as long as its maximum width; hind coxa mostly smooth laterally, with sparse fine punctures and rather dense setae; hind femur largely rugose-punctate laterally. First metasomal tergite 1.15 × longer than its apical width; dorsal carinae in basal 0.6 of tergite; first tergite areolate-rugulose medially ( Fig. 2H View FIGURE 2 ); median length of second tergite 0.6 × its apical width; second tergite 0.8 × as long as third tergite; second tergite foveate-reticulate medially; the remaining tergites shiny, smooth.
Notes. W. phiaoaca sp. nov. is similar to W. bifurcata Yan & van Achterberg , but can be distinguished by the following characters: 1) vein 1-M of hind wing 0.7 × 1r-m (vs 1.1 × in W. bifurcata ); 2) hind femur rugo-punctate laterally (vs sparsely punctate in W. bifurcata ), and 3) second metasomal tergite foveate-reticulate medially (vs rugo-punctate medially).
The new species is also similar to W. coffeana Long , but differs from the latter by the following characters: 1) frontal protuberance lamelliform, bifurcate, with distinctly ledge halfway and acute dorso-posteriorly (vs frontal protuberance lamelliform, with ledge halfway and blunt dorso-posteriorly); 2) first metasomal tergite subequal to its apical width (vs 1.1 × in W. coffeana ); 3) length of hind femur 3.05 × as long as its maximum width (vs 3.7 × in W. coffeana ); 4) outer side of hind coxa punctate, and of hind femur rugo-punctate (vs hind coxa nearly smooth and hind femur sparsely punctate). Wroughtonia phiaoaca sp. nov. runs out to couplet 4 in the key by Long et al. (2020) as follows:

Frontal protuberance lamelliform, bifurcate and acute dorso-posteriorly (4a); Hind femur slenderer, weakly concave apicoventrally, its length 3.7 × as long as maximum width, outer side of hind femur sparsely punctate, sparsely setose ventrally (4aa); second submarginal cell of fore wing narrowed apically (see Fig. 35 in Long et al. 2020); vein 2-M of fore wing 2.6 × 3-SR..................................................................................
