Trichobothriatrichobothrium:
(pl. trichobothria) (= bothridial sensillum) an often elaborately modified seta set in a cup-like base; forms include filiform, ciliate, pectinate or variously thickened or clubbed (bat-like to globose or capitate).
are modified setae associated with a cup-like insertion call a bothridiumbothridium:
the cup-like base of a bothridial sensillum.
. They are thought to be sensitive to air-currents and act as movement sensors (i.e., telling the mite that something is moving near them and displacing air). Trichobothriatrichobothrium:

the anteriormost pair of prodorsal setae or an unpaired median seta (Nematalycoidea) in the Acariformes; when a naso is present, it often carries the rostral setae; various designations: ro, vi, v1. (ro = vi).
