Trichobothria are hair sensilla on the integument of various terrestrial arthropods. They are characterized by a cup-shaped cuticular structure (Latin bothrium, cup) out of which a hair (Greek ϑϱίξ, τριχόç, hair) protrudes into the air. This hair is either long and thin (therefore in insects the sensillum is usually referred to as thread-hair) or it has the shape of a racket or a club. In spiders trichobothria have been known for a century. In 1883 Dahl observed that they were deflected by the sound of a violin and therefore called them Hörhaare (hairs of hearing). The racket-shaped trichobothria were described by Simon in 1892. The respective literature on spider trichobothria has been reviewed by Chrysanthus (1953), Schuh (1975), Krafft and Leborgne (1979) and Barth (1982).
