Chorioptes bovis Gnavemide (Chorioptic/"chewing" mange mite)
Order: Acarina: Mites and ticks | Suborder: Sarcoptiformes: Mange mites.
Specific morphology: In the female a large mite egg (ca 0.1 mm) can be seen centrally. Suckers on leg pairs 1, 2 and 4.		Specific morphology: Male with suckers on all pairs of legs. Copulatory suckers and truncated tubercles posteriorly.
Hosts: Cattle, sheep, equines.
Location: The mite lives on the surface of the skin and consumes epidermis scraps.
Causes tail scab in cattle on tail root and perineum, ‘foot mange’ in sheep and also in horses, i.e. on pasterns (C. equi). Host-specific varieties morphologically indistinguishable!
General morphology of Chorioptes: Non-burrowing, mange mites resembling Psoroptes (e.g. long legs), except that the oval body is shorter (length: 0.4-0.6 mm) and the mouthparts rounded (chewing type). Sucker-bearing pairs of legs with large cup-shaped suckers on short unjointed pedicels.
