| description |
A dark reddish-brown species with a noticeably long, pointed head; the vertex is about two times as long as the width between the eyes. The crown is mottled brown to reddish-brown with some light markings, in particular a pale midline with a thin pale diagonal stripe on either side. The pronotum and scutellum are both brown with dark markings. The face is dark, typically a dark reddish-brown that is somewhat concolorous with the crown. The wings are brown to reddish-brown, with dark irrorations and white areolar spots scattered throughout. The male subgenital plates are elongate and almost as long as the pygofers; they are triangular. The female pregenital sternite has short lateral margins and a posterior margin that is straight on either side of a blunt apex. Adult males are around 4.2 mm long, while females are around 4.8 mm. (DeLong 1948), (Hepner 1947)

| comments |
NOTE: Many US species of Scaphytopius are very similar externally to one another and are variable in coloration. Triangularis resembles several species that occur in our area, including rubellus, magdalensis and, as of now, a male specimen is needed to determine an individual is conclusively triangularis. |
