Pretarsal claws

Uncinateuncinate:
hook-like
means having a hookhook:
(as in cheliceral hook) the distal hook-like tips of chelicerae in the Mesostigmata, as opposed to cheliceral teeth.
. Pad-likepad-like:
in Prostigmata, used to refer to empodia that do not have a distal hook (claw-like); when tenent hairs are present a 'pad-like' empodium may look more like a pincushion; in other Acari, usually a simple, pad-like empodium.
refers more to the absence of a hookhook:
(as in cheliceral hook) the distal hook-like tips of chelicerae in the Mesostigmata, as opposed to cheliceral teeth.

appearance, since a profusion of tenent hairs often obscures the empodial basebase:
the usually columnar basal part of the tritosternum; sometimes expanded and rectangular or otherwise modified; the most basal part of any structure.
. Spider mites that have empodiaempodium:
(pl. empodia) an unpaired structure arising between the tarsal claws, ranging from pad-like to claw-like and often bearing structures such as tenent hairs, dense setulae, or taking the form of a featherclaw (Eriophyoidea)..
with tenent hairs belong to the Subfamily Bryobiinae. The three tribes of Bryobiinae can be separated by the characteristics of the pretarsal claws and empodia:empodium:
(pl. empodia) an unpaired structure arising between the tarsal claws, ranging from pad-like to claw-like and often bearing structures such as tenent hairs, dense setulae, or taking the form of a featherclaw (Eriophyoidea)..
