The highly complicated structure of the trichobothrium in the whip scorpion Typopeltis crucifer (Uropygi, Arachnida) has been reconstructed from ultra‐thin serial sections. The spatial positions of two trichobothria on the first pair of legs, as well as their innervation by several dendrites point to an effective spatial localization of stimulus sources. Numerous cells are involved in the regeneration of the trichobothrium during moulting. They can be classified according to their position and function in forming the sensillum: there are 11 sensory cells, four inner envelope cells, about 21 trichogen cells and numerous outer envelope cells, including tormogen cells. The complicated cell pattern is compared to conditions in similar sensilla of other arthropods in terms of function and phylogeny.
