An adult<unk>  is about 1.3–2 mm long (slightly smaller than the body louse and head louse), and can be distinguished from those other species by its almost round body. Another distinguishing feature is that the second and third pairs of legs of a<unk>  are much thicker than the front legs and have large claws.
