Diagnosis

The female of S. bokkeveldensis Kuhlmann sp. nov. can be separated from all other species of this group by the combination of the following characters: supraclypeal area and clypeus superficially sculptured but shiny, sparsely and coarsely punctate ( Fig. 2B ); scutum relatively densely and coarsely punctate ( Fig. 2C ); propodeum only laterally with distinct but fine carination ( Fig. 2D ); stigma brown; apical margins of metasomal terga black; terga finely and densely punctate ( Fig. 2E ). The male is unknown.

Antenna dorsally blackish-brown, ventrally yellowish-brown.

MESOSOMA. Integument black, tegula dark reddish-brown. Mesoscutal disc between punctures superficially shagreened and slightly matt; disc relatively densely (i = 1–2 d) but relatively coarsely punctate ( Fig. 2C ). Metanotum about as long as basal area of propodeum, apically with distinct narrow carinate depression ( Fig. 2D ). Propodeum basally only laterally distinctly but relatively finely carinate ( Fig. 2D ). Mesoscutum, scutellum, metanotum, mesepisternum and propodeum sparsely covered with short, greyish, erect hair ( Fig. 2A ).

Prepygidial and pygidial fimbriae relatively short, brownish. T1–T4 densely (i = 0.5–1 d) and relatively coarsely punctate, T1–T2 between punctures smooth and shiny, T3–T4 between punctures superficially reticulate but shiny; T2–T4 with polished and shiny apical tergal depression ( Fig. 2E ).
