In Parasitiformes and most Acariformes the legs are inserted more or less contiguously and the coxae or coxal fieldscoxal fields:
the venter of acariform mites where the coxae have fused to the body wall covering the sternal region.
are approximateapproximate:
close together, near, adjacent
. However, in several acariform lineages coxae II are separated from coxae III either by expanded coxal epimeraepimere:
(pl. epimera) (also epimeron) in oribatid mites, a sclerotized coxal field; in Astigmata, anterior coxal apodeme.
II and III or by a 'stretching' of the middle of the bodybody:
the idiosoma of mites.
. The latter are typically elongate mites.
