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.

Named after the Avontuur Nature Reserve where this species was discovered.
