| description |
A very distinctive member of this genus, with intense grayish-white and dark brown coloration. The crown is whitish with a thin, dark-brown marginal line, a transverse orange band between the eyes with a darker diamond shape in the middle, sometimes extending towards the pronotum. The eyes are dark brown to blackish, the face is brown to blackish (this varies among individuals) with one to three darker brown lines below the crown; the areas below the eyes on the side of the head are blackish. The pronotum is dark brown with a medial whitish-gray cruciate pattern; the posterior margin can be pale. The scutellum posterior half is yellowish-white with black marks on the lateral margins; the anterior half has a dark brown trapezoid-like shape in the middle and an orange-brown square on either side. The wings have a grayish-white base color with brown to blackish venation. There is a blackish diagonal band at the base of each wing and a broad dark-brown to black transverse vertical bar about 2/3 of the length of the wings; this wing pattern is distinctive and characteristic of this species. The wing tips have a smoky orange tint to them. The female pregenital sternite is anteriorly yellow and posteriorly brownish-black. The male subgenital plates are trapezoid-like in shape with blunt, rounded apices. Adult males are 4.9-5.3 mm long, females are 5.3-5.9 mm. (Barnett 1976)

| comments |
This species could maybe be confused with some individuals of S. opalinus, as both species have a similar gray coloration on the wings. Note however that opalinus lacks the characteristic dark wing bands found on S. obtusus; obtusus is also much darker on the face and underside. |
