Diagnosis

The female of S. nigerrimus sp. nov. can be separated from other species of this group by the combination of the following characters: supraclypeal area and clypeus densely and distinctly punctate, mostly smooth and shiny ( Fig. 18 C–D), scutum densely and coarsely punctate ( Fig. 18 E–F), stigma brown, apical margins of metasomal terga black, terga finely and densely punctate ( Fig. 18B ). The male is unknown.
