The fauna of Onychiurinae were investigated in different parts of Kermanshah province during 2013–2014. Specimens were collected from both leaf litter and surface layer of the soil in Oak forest (Quercus infectoria), Elm trees and grasslands). Totally four species from three genera were found. All of them are new for Kermanshah province and Protaphorura levantina (Christiansen, 1956) and Vibronychiurus archivari (Christiansen, 1956) were not previously recorded in Iran; it is also the first time that the genus of Vibronychiurus Pomorski, 1998, is collected and reported for the country.
