Figs 21–22

Diagnosis

The female of S. papkuilsi sp. nov. can be separated from other species of this group by the combination of the following characters: head about as long as broad, supraclypeal area and clypeus densely and distinctly punctate, only partly superficially sculptured and matt (Fig. 21B), scutum densely but relatively finely punctate, metanotum apicaly with carinate depression (Fig. 21 C–F), stigma brown, apical margins of metasomal terga black, terga densely and coarsely punctate (Fig. 21 G–H). The male is characterized by an unmodified antenna, hind tibia apically broadened inside and pointed (Fig. 22E), relatively finely but densely punctate scutum and metasomal terga (Fig. 22C) and the form of S7 (Fig. 22D).

Etymology

Named after Farm Papkuilsfontein south of the town of Nieuwoudtville, where most of the specimens were collected.

Metanotum slightly shorter than basal area of propodeum, apically with narrow carinate depression (Fig. 21D, F). Propodeum basally shallowly but broadly carinate (Fig. 21D, F). Mesoscutum, scutellum, metanotum, mesepisternum and propodeum sparsely covered with short greyish to brownish, erect hair (Fig. 21A).
