Diagnosis
The female of S. pygmaeus sp. nov. can be separated from other species of this group by the combination of the following characters: supraclypeal area and clypeus sparsely but distinctly punctate, mostly finely sculptured and slightly matt (Fig. 25B), scutum reticulate, sparsely and shallowly punctate, basal area of propodeum basally indistinctly carinate (Fig. 25 C–D), stigma brown, apical margins of metasomal terga black, terga impunctate (Fig. 25E). The male is unknown.
Etymology
Named for the small body size of the species.
