In a faunistic study، eviphidoid mites (Acari: Mesostigmata) in Nowshahr county (western Mazandaran province) during 2009-2010، a total of 23 species from superfamily Eviphidoidea belonging to eight genera and three families were collected and identified from different soil and manure habitats. Five species of Pachylaelaps insularis (Berlese)، Olopachys compositus (Koroleva)، Olopachys caucasicus (Koroleva)، Onchodellus cf alpinus (Willmann)، Gamasholaspis incisus Petrova and the genus Gamasholaspis Berlese were new records from Iran. Among collected families، Macrochelidae had the highest relative frequency (55. 77 percent)، and the families Pachylaelapidae and Parholaspididae with frequencies of 30. 21 and 14. 02 percents were in next ranks، respectively. No specimen of Eviphididae was collected in this study. The most frequent species of the first three families were Glyptholaspis americana (Berlese) (8. 52 percent)، Olopachys caucasicus (Koroleva) (9. 3 percent)، and Holaspina alstoni Evans (13. 25 percent).
