Introduction Taxonomic History (provided by Barry Bolton, 2013) Identification. This species can really only be confused with one other species, S. pergandei, S. angulata differs by having the anterior and lateral margins of the clypeus meeting in angular corners (see full face photo above), rather than rounded curves (as in S. pergandei); the second tooth on the mandible is longer than the basal tooth, whereas, in S. pergandei, the basal tooth is longer than the second or third tooth; the postpetiolar disc lacks posteriorly curved spatulate hairs (present in S. pergandei); and the mesonotal dorsum has a pair of erect simple hairs (lacking in S. pergandei).
