Leg suckers have a short pedicel without segments.
Females have suckers on legs 1, 2 and 4.The fourth legs are long, those of the male are short. Chorioptes mites, which are surface-inhabiting parasites found principally on the feet of domesticated animals, produce chorioptic mange, a common cause of dermatitis in cattle, sheep, goats, and occasionally horses in most parts of the world.
Males have suckers on legs 1, 2, 3 and 4, a pair of lobes of square ended shape at the back of the body, and a pair of copulatory suckers. The potential economic significance of them lies in the irritation they cause and the lesions they produce. As the mites feed on epidermal debris the infection rarely results in serious damage to the skin.
Currently, five species belonging to the genus Chorioptes are recognized, but only Chorioptes bovis and Chorioptes texanus are associated with domesticated ungulates.
