Ovigerous female of Ornithocheyletia hallae, from Macchioni (2003).

Belongs within: Cheyletiellidae.

The Ornithocheyletiini are a group of cheyletid mites specialised for parasitism on birds, characterised by enlarged tarsal claws with an apical knob on the dorsum of the tarsus almost completely covering the pretarsus and claws (Bochkov & Fain 2001).

Characters (from Bochkov & Fain 2001): Gnathosoma less than 30% of idiosomal length, without protrusions. Gnathosomal apex with short median protuberances. Palpal tarsi with 4-3 short nude setae. Palpal claws curved ventrolaterally, without teeth, not thickened. All setae of palpal tibia hair-like. Palpal femur with three setae, palpal genu with two setae not fused with femur, without protrusions or with small protrusions. Idiosoma ovate. Eyes absent. Shoulder-like projections of idiosoma absent. All idiosomal setae, excluding 15, not exceeding half of idiosomal length. Neotrichial setae absent. Length of all legs not exceeding idiosomal length. Legs IV normally developed. Tarsi thickened with knobs covering pretarsus. Guard seta of tarsus I hair-like, solenidion ω1 situated in apical half of tarsus I. Tibia I with solenidion. Tibia II without solenidion. Genu I with rod-like solenidion or globular. Seta v1 of tarsus I situated at same level as solenidion ω1 and guard seta. Pretarsus and well-developed claws present on all legs. Apical seta of tarsus I normally long. Tarsal setae p' and p" hair-like, but sometimes deeply dissected or feather-like. Coxae III with 2-1 setae. Trochanters III-IV with or without seta. Distance between coxae II and III less than half of the idiosomal width.
