Diagnosis

The female of S. keiskiensis 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 sculptured and matt, densely and distinctly punctate (Fig. 5B); scutum densely and relatively coarsely punctate (Fig. 5C); propodeum indistinctly and shallowly carinate (Fig. 5D); stigma brown; apical margins of metasomal terga black or only slightly translucent dark reddish-brown; terga between punctures superficially sculptured and slightly matt (Fig. 5E). The male is unknown.

Etymology

Named after the Keiski Mts south of Calvinia where this species was first collected.

Antenna dorsally blackish-brown, ventrally yellowish-brown.

MESOSOMA. Integument black. Mesoscutal disc between punctures reticulate and matt; disc densely (i = 0.5–1 d) and relatively finely punctate (Fig. 5C). Metanotum slightly shorter than basal area of propodeum, apically with narrow carinate depression (Fig. 5D). Propodeum basally distinct but very finely carinate (Fig. 5D). Mesoscutum, scutellum, metanotum, mesepisternum and propodeum sparsely covered with short, greyish, erect hair (Fig. 5A).
