* SYNOPSIS OF THE DESCRIBED ASTIGMATA OF THE WORLD

------------

The Astigmata are one of the orders of mites. They belong to the Sarcoptiformes, which contain the "biting" Acariformes. Many species are parasites of vertebrates. Most notorious among these are the Psoroptidia, which contain such notable taxa as feather mites and Sarcoptes scabiei.

The Astigmata are of unclear relationships to those mites commonly united as Oribatida. The latter appear to be paraphyletic and in need of division into two orders, as some of them (e.g. certain Desmonomata) seem closer to Astigmata than to other Oribatida.
