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.

Female

BODY LENGTH. 5.4 mm.

HEAD. Head distinctly wider than long. Integument black, except part of mandibles dark reddish-brown. Face sparsely covered with long, greyish, erect hair ( Fig. 5B ). Clypeus slightly convex with dense (i = d) punctation, apically finer, basally coarser; surface between punctures sculptured and matt ( Fig. 5B ). Malar area medially narrow, almost linear. Antenna dorsally blackish-brown, ventrally yellowishbrown.

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 ).

WINGS. Brownish; wing venation and stigma brown.

METASOMA. Integument black, apical margins on first terga narrow, on other terga broadly black to translucent dark reddish-brown ( Fig. 5E ). Disc of T1–T2 without hair; following terga with very short but increasingly more and longer hair; apical tergal hair bands missing on all terga ( Fig. 5E ). Prepygidial and pygidial fimbriae relatively short, yellowish-brown. T1–T4 finely and densely (i = 0.5–1 d) punctate, between punctures superficially sculptured and slightly matt; T2–T4 with superficially reticulate but shiny apical tergal depression ( Fig. 5E ).
