Chaetotaxy

Chaetotaxy is the arrangement of bristles (macrochaetae) on an insect or mite, or taxonomy based on their position and size. For example, it is important in Diptera, in which group it was formalised by Ernst August Girschner. The term chaetotaxy was later proposed by Carl Robert Osten-Sacken.
