Knemidocoptes pilae.

The genus is also spelt Cnemidocoptes. Main body features are similar to Sarcoptes, but the dorsal surface has only faint and irregular scales, no spines and the anus is dorsal. The species cause mange of the legs, base of the beak, vent area, and back of parakeets and canaries, respectively; the burrowing activity of the female is principally responsible for the dermatitis produced.
