Diagnosis

The female of S. avontuurensis Kuhlmann sp. nov. can be separated from all other species of this group by the combination of the following characters: head distinctly broader than long; supraclypeal area and clypeus relatively sparsely and coarsely punctate, only partly superficially sculptured and slightly matt (Fig. 1B); scutum densely but relatively coarsely punctate (Fig. 1C); propodeum basally broadly and distinctly carinate (Fig. 1D); stigma brown; apical margins of metasomal terga broadly translucent dark reddish-brown; terga between punctures superficially sculptured and slightly matt (Fig. 1E). The male is unknown.
