Abstract

Faunistic study of cryptostigmatic mites (Acari: Oribatida) in Rasht township was conducted during 2008-2009. Mites were extracted using Berlese funnel from soil samples and cleared in lactophenol. Cleared mites were mounted (in Hoyer’s medium) on microscopic slides. In total, 15 species, 15 genera and 13 families of oribatid mites (Acari: Oribatida) were collected and identified. Among the identified specimens, 12 species, 11 genera and 8 families are for the first time records from Guilan province while one species, two genera (with unknown species) and two families are the first record from Iran.
