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.

Named after the Ouberg Pass southeast of Vanrhynsdorp.

Antenna dorsally blackish-brown, ventrally yellowish-brown.

MESOSOMA. Integument black, tegula dark reddish-brown. Mesoscutal disc between punctures reticulate and slightly matt; disc sparsely (i = 1.5–2.5 d) and coarsely punctate ( Fig. 9C ). Metanotum slightly shorter than basal area of propodeum, apically with distinct narrow carinate depression ( Fig. 9D ). Propodeum basally broadly and coarsely carinate ( Fig. 9D ). Mesoscutum, scutellum, metanotum, mesepisternum and propodeum sparsely covered with short, greyish, erect hair ( Fig. 9A ).

Disc of T1 without hair; following terga with very short but increasingly more and longer hair; apical tergal hair bands missing on all terga ( Fig. 9E ); prepygidial and pygidial fimbriae relatively short, blackish-brown. T1 finely and densely (i = d) punctate, between punctures smooth and shiny; T2– T4 slightly coarser punctate; T2 between punctures basally superficially reticulate but shiny, apically smooth; T3–T4 between punctures superficially reticulate and slightly matt; T2–T4 with polished to superficially sculptured, but shiny apical tergal depression ( Fig. 9E ).
