First record of the eriophyid mite, Aculus dimidiatus (Hall) (Acari: Eriophyidae) on eastern cottonwood (Populus deltoides) (Salicaceae) in Iran

In 2008, in a field survey on mites associated with poplar trees in Razavi Khorasan province (NE.Iran), specimens of an eriophyid were collected. The specimens were sent to Dr Xia-Yue Hong for identification. As result, the eriophyid Aculus dimidiatus (Hall) is recorded from Iran for the first time. The eriophyid reported here was found vagrant on under surface of leaves of eastern cottonwood (Populus deltoides) (Salicaceae). Samples of this mite are held in the author's collection at the Ferdowsi University of Mashhad, Iran and in Dr Hong's collection at Nanjing University, China.
