Mites of the genus Anomaloppia Subías (Acari: Oppiidae) from Alborz province, northern Iran, with one new species and a key to the known species

In the course of a faunistic survey on oribatidmites in Alborz province, northern Iran, four species belonging to the genus Anomaloppia were collected: A. iranica, A. mazandaranica, A. differens and a hitherto unknown species which is named as A. alborzi sp. n. The new species is characterized by the rostral setae which are situated close to each other and by long sensilli, with a fusiform head and four long barbs and by smooth notogastral setae. Anomaloppia differens is recorded for the first time from Iran and a supplementary description is provided for this species on the basis of Iranian materials. An identification key to the species of Anomaloppia is given.
