MESOSOMA. Integument black. Mesoscutal disc between punctures densely reticulate, matt; disc sparsely (i = 3–5 d) and shallowly punctate (Fig. 11 E–F). Metanotum slightly shorter than basal area of propodeum, apically with narrow carinate depression (Fig. 11F). Propodeum broadly but finely carinate (Fig. 11F). Mesoscutum, scutellum, metanotum, mesepisternum and propodeum sparsely covered with short, greyish, erect hair (Fig. 11A).
