The cheyletid mites collected from Guilan province in Northern Iran were investigated.
A total of 16 species were determined. Of these, Eucheyletia flabellifera (Michael, 1878)
is a new record for the Iranian cheyletid mite fauna. Herein, we provide an expanded
description, including illustrations of the adult female of this species based on the Iranian
material. A tabulated checklist for cheyletid mites recorded from Iran is also provided.
