Modern conceptions concerning the macrophylogeny of acariform mites (Chelicerata,Acariformes)

Modern conceptions concerning the macrophylogeny of acariform mites assumed during the last thirty years are summarized. Arguments supporting the hypothesis assuming the monophyly of mite taxa of higher taxonomic ranks (above the superfamily level) are discussed. The main unsolved problems of the phylogeny of the order Acariformes are mentioned. A new provisional classification of the order Acariformes for the taxa ranking from the suborder to the superfamily is proposed.
