During field surveys of eriophyoid species associated with rosaceous plants in Zagros forests of Iran, three new species were discovered and described including Eriophyes cotosarica sp. nov. from Cotoneaster hissaricus Pojark., Eriophyes cratameyeris sp. nov. from Crataegus meyeri Pojark. and Eriophyes pyrusyriaca sp. nov. from Pyrus syriaca Boiss. All species cause galls on their host plant’s leaves. In addition, a list of Eriophyes species found on Rosaceous plants in Iran and a supplementary description of Eriophyes pyri (Pagenstecher, 1857) are provided.
