The amount of black on the wings can vary among individuals, and males are darker than females. This species has a dark, reddish underside of the abdomen and thorax. The face is black with a pale midline. The head is somewhat rounded and lacks the sharpness that other members of this genus have. This is a small species, smaller than other members of this genus, being 3.5-4.5 mm. (UDEL)

While S. brunneus is a fairly distinctive species, it could be confused with a couple other Stenocranus. It is most likely to be confused with S. acutus, which has similar coloration. However, the key differentiating factor is the shape of the head. In S. acutus, the head is very pointed, forming a sharp angle when viewed from the side; however, in S. brunneus the head is more rounded and lacks the sharpness. Additionally, S. acutus has a longer, narrower body shape than brunneus. The other similar species is S. lautus, which typically is not as dark as S. brunneus, with a different wing pattern. The two species are also noticeable different in size, with lautus typically around 5.0 mm in length and brunneus less than 5.0 mm, listed as 3.5-4.5 mm. |
