Description: A somewhat dark brownish species, resembling S. acutus dorsally but with a brown rather than a yellow face. The vertex is bluntly angled, about 1.5 times as long as the width between the eyes. The crown is brown mottled with yellow and with white longitudinal lines. The pronotum is dark brown (darker than the crown) with five pale longitudinal lines and heavily irrorate overall; the scutellum is paler, more orange in color. The wings are brown, with dark wing venation and many white areolar and small black dots. The male subgenital plates are somewhat elongate and triangular, with convexly rounded bases and tips that diverge from one another. The female pregenital sternite has a rounded posterior margin. Adults are 4.0 mm long. (DeLong 1948), (Hepner 1947)
