Diagnosis

The female of S. nitens Kuhlmann sp. nov. can be separated from all other species of this group by the combination of the following characters: clypeus almost flat ( Fig. 8B ); scutum sparsely and coarsely punctate ( Fig. 8C ); foretibia dominantly dark blackish-brown; stigma brown; apical margins of metasomal terga broadly yellowish-brown; metasomal terga between punctures smooth and shiny ( Fig. 8E ). The male is unknown.

Etymology

The name comes from the Latin ‘ nitens ’, meaning ‘glossy’, and referiing to the shiny appearance of the species.

Malar area medially narrow, almost linear. Antenna dorsally blackish-brown, ventrally yellowish-brown.

MESOSOMA. Integument black, tegula reddish-brown. Mesoscutal disc between punctures smooth and shiny; disc sparsely (i = 1.5–3 d) and coarsely punctate ( Fig. 8C ). Metanotum slightly shorter than basal area of propodeum, apically with indistinct narrow carinate depression ( Fig. 8D ). Propodeum basally only laterally broad and coarsely carinate ( Fig. 8D ). Mesoscutum, scutellum, metanotum, mesepisternum and propodeum sparsely covered with short, greyish, erect hair ( Fig. 8A ).
