A new family of eupodine Prostigmata, Eriorhynchidae fam.n. , is established to accommodate Eriorhynchus gen.n. , and five species from Australia: E.australicus (Womersley), E.hades sp.n. , E.ramosus sp.n. , E.walteri sp.n. and E.womersleyi sp.n. The new family is unique in the possession of 15–34 setae on the gnathosomatic base, a naso‐prodorsal process with 9–28 setae and a palp tibia with 6 or 7 setae. A key to the families of Eupodoidea is provided. A cladistic analysis of twenty‐seven eupodoid species from Australia and New Zealand is presented. Results indicate that the genus Eriorhynchus gen.n. (thus Eriorhynchidae) is monophyletic, and the Australian and New Zealand species of Halotydeus Berlese, Penthaleus C. L. Koch, Rhagidia Thorell and Stereotydeus Berlese form separate monophyletic goups, while the Penthaleidae are not monophyletic. The new family Eriorhynchidae is a sister group to a clade consisting of Penthaleus and Chromotydaeus quartus Qin & Halliday.
