Chaetotaxy
Encyclopedia
Chaetotaxy is taxonomy
based on the position and size of bristles
on an insect or the arrangement itself. It is especially important in Diptera
in which group it was formalised by Ernst August Girschner
.
The chaetotaxy of a fly might include :- acrostichal, dorsocentral, humeral, mesopleural, sternopleural , notopleural , postalar, supraalar and scutellar bristles on the thorax ; dorsal, posterodorsal, anterodorsal, ventral, posteroventral and anteroventral bristles on the legs and ocellar, orbital, postvertical, vibrissal, outer vertical and inner vertical bristles on the head.
