Diagnosis

The female of S. oubergensis Kuhlmann sp. nov. can be separated from all other species of this group by the combination of the following characters: supraclypeal area and clypeus coarsely and densely punctate and shiny, only partly superficially sculptured and slightly matt (Fig. 9B); scutum coarsely but relatively densely punctate (Fig. 9C); basal area of propodeum medially about as long as metanotum (Fig. 9D); stigma brown; apical margins of metasomal terga black; terga densely and finely punctate (Fig. 9E). The male is unknown.
