Phytoseiidae family mites are found in different natural ecosystems e.g. medicinal plants. They have beneficial role in reduction population of Two Spotted Spider Mites (TSSM). Up to species diversity they are not studied. In order to this survey mites associated with areal part of plants including: Betony, Strawberry, Chickory, Astragalus, Mint, Falcaria, Greater plantain, Yarrow, Raspberry, Common sage, Tamarikis, Salsify and Alfalfa, in some parts of Hamedan, Kurdistan and Ardabil provinces, in 2009–2011, were collected (shaking method and Berlese funnel). All specimens were directly mounted on permanent microscopic slides using Hoyer’s medium. And also the specimens were identified and examined under an Olympus BX51 microscope. In this study, the 11 species belonging 6 genera in this family are the following: Amblyseius obtusus (Koch, 1839), Proprioseiopsis messor (Wainstein, 1960), Neoseiulus barkeri Hughes, 1948, Neoseiulus bicaudus (Wainstein, 1962), Neoseiulus marginatus (Wainstein, 1961), Neoseiulus sugonjaevi (Wainstein & Abbasova, 1974), Neoseiulus tauricus (Livshitz & Kuznetsov, 1972), Neoseiulus zwoelferi (Dosse, 1957), Paragigagnathus insuetus (Livshitz & Kuznetsov, 1972), Phytoseius plumifer (Canestrini & Fanzago, 1876), Typhlodromus (Anthoseius) tamaricis Kolodochka, 1982.
