Cheyletidae

Dorsum of Cheletogenes ornatus, from Qing-Hai Fan.


Belongs within: Cheyletoidea.
Contains: Cheyletiini, Acaropsellini, Cheyletini, Cheyletiellidae.

The Cheyletidae are a group of predatory or vertebrate-associated mites that often bear large raptorial setae on the pedipalps. They have been divided between subfamilies Cheyletinae and Cheyletiellinae based on the presence or absence, respectively, of comb-like setae on the palpal tarsi and teeth on the palpal claw, but it seems likely that the 'Cheyletinae' are paraphyletic (Bochkov & Fain 2001).

Characters (from Baker 1949): Chelicerae short, stylet-like. Palpi large and pincer-like; tarsus short, located on posterior part of tibia rather than on tip, in most cases bearing comb-like and sickle-like setae; tibia with strong claw extending beyond tarsus. Dorsum of body with none, one, or more plates.
