Eriophyoid (Trombidiformes: Eriophyoidea) mite fauna of Miandoab region in Iran with redescription of Aceria kiefferi (Nalepa)

During the study of the eriophyoid mite fauna of Miandoab region (West Azerbaijan province, Iran), specimens of two eriophyoid families, four subfamilies, four tribes, 11 genera and 19 species were collected and identified. Among them, three species including Aceria kiefferi (Nalepa), Phyllocoptes bilobospinosus Chetverikov and Diptacus gigantorhynchus (Nalepa) were recorded for the first time in Iran. The most abundant species was Acalitus phloeocoptes (Nalepa) and six other species including Aceria cf. tosichella Keifer, A. anthocoptes (Nalepa), Calepitrimerus baileyi Keifer, Aculus fockeui (Nalepa & Trouessart), Abacarus cf. hystrix (Nalepa) and Rhynophytoptus nemalobos Lotfollahi & de Lillo were abundant species in the surveyed region. The old species A. kiefferi is redescribed and illustrated herein, according to the current standard, due to the poor details of the previous old descriptions.
