Relatively small
Red tail tip separated by black from pale hairs on T1 and T2 (at least mediobasally) in combination with some admixture of black hairs on the anterior scutum is distinctive. Males have a distinctive patch of dense hairs on basal segments of their flagellum (only visible from certain angles) and this is useful for separating them from frigidus. Also, in mixtus males the red tail tip is separated from yellow basal tergal segments. In mixtus the apicolateral corners of T2 are often black whereas in frigidus all of T2 is yellow.
