A new species, Bak iranica n. sp. (Acariformes: Prostigmata: Cheyletidae) is described on the basis of adult males from Amol, Mazandaran province, northern Iran. The new species can be distinguished from other species by the following features: having one seta on each trochanter, tarsi I–IV with 9(+1°)–7(+1°)–7(+1°)–7(+1°); a palpal claw with two basal teeth and most of the dorsal body setae slightly lanceolate and barbed. Additionally, a key to world species (females and males) of the genus Bak Yunker is provided. This genus is recorded from Iran for the first time.
