The following changes in authorship and PriOrity of family-group names for heterostigmatic mites are made in accordance with the International Code of Zoological Nomenclature and in the interest of historical accuracy. 1) The name Tarsonemidae, with all of its coordinate categories (including tribe, subfamily, superfamily), should take CANESTRINI and FANZAGO, 1877, rather than KRAMER, 1877, as authors. 2) The name Podapolipidae should take EWING, 1922, rather than OUDEMANS, 1931, or VITZTHUM, 1931, as author. 3) The name Scutacaridae OUDEMANS, 1916, with all of its coordinate categories, has priority over Pygmephoridae CROSS, 1965, for whichever family-group taxon is recognized as a monophyletic lineage that comprises both of these sublineages.
