Diagnosis.

Wilkinsonellus can be differentiated from other Microgastrinae genera by the combination of the following characters: body coloration largely yellowish (Figs 1A, L; 3A; 4A); propodeum with a median carina, spiracles surrounded by carinae (Figs 1F, 3G, 4H); propleuron with a posterior flange (Figs 1D, 3F, 4B); scutellum sculptured medio-posteriorly and often with subapical carina (Figs 1M–N, 3G, 4H); lunulae of scutellum wide (Figs 1E–F, 3G, 4G–H) (Long and Achterberg 2011), fore wing with second submarginal cell (“areolet”) open distally, thus vein r-m absent (Fig. 3J); vein 1-1A strongly curved, laying very close to posterior margin of the fore wing (Fig. 3J) (Long and Achterberg 2003); tergite I with petiole 4–5 times as long as its apical width, more or less constricted medially and deeply grooved almost to apex (Figs 1H, Q–R; 3H; 4H–I) (Zeng et al. 2011); median longitudinal area of metasomal tergite II slightly raised, usually poorly delimited (Figs 1G–H, Q–R; 3H, L; 4I), tergite II as long as tergite III, both smooth (Figs 2G–H, Q–R; 3H, L; 4I) (Whitfield 1997); hind coxa enlarged (Figs 1A, I, L, Q; 3A, H, L,) rarely short except in Wilkinsonellus flavicrus (Long and Achterberg 2011); ovipositor sheaths short (Figs 1A, G, J, 4A, J) (Whitfield 1997).
