Cheyletiella
Cheyletiella is a genus of mites that live on the skin surface of dogs, cats, rabbits, and humans.
The adult mites are about 0.385 millimeters long, have eight legs with combs instead of claws, and have palpi that end in prominent hooks. They do not burrow into the skin, but live in the keratin level. Their entire 21-day life cycle is on one host. They cannot survive off the host for more than 10 days.
