Members of superfamily Raphignathoidea are important biological control agents of spider mites, eriophyid mites and scale insects in agriculture and forestry. They were found in various ecosystems: foliage, branches, trunks, moss and lichen, litter, soil, animal nests, stored products and even in house dust (Fan & Zhang, 2005). Superfamily Tetranychoidea are obligatory phytophagus mites assigned to five recognized families. Most of species that are of major economic importance are contained in two families, Tetranychidae or spider mites and Tenuipalpidae or false spider mites (Krantz & Walter, 2009). During 2014, fauna of the superfamilies Raphignathoidea and Tetranychoidea in Ramsar town were studied. In this order, samples were collected and directly mounted in Hoyer’s medium. In total 16 species, belonging to 9 genera and 6 families were identified. Among them, 7 species belonging to families Cryptognathidae, Raphignathidae and Stimaeidae (superfamily Raphignathoidea) and 9 species belonging to families Tenuipalpidae, Tetranychidae and Tuckerellidae (superfamily Tetranychoidea). Favognathus guilanicus,Panonychus citriandEustigmaeus segnishad high population on sweet orange trees and lichen respectively. Identified species are listed as follow: Stigmaeidae: Eustigmaeus:E. seemani Khanjani et al., 2013; E. segnis(Koch, 1836);E. nasrinae Khanjani & Ueckermann, 2002; Cryptognathidae: Favognathus: F. esfahaniensis Khanjani et al., 2014; F. guilanicusKhanjani et al., 2014; Raphignathidae: Raphignathus:R. zhaoi Hu et al., 1995; R. hecmataniensisKhanjani & Ueckermann, 2002; Tenuipalpidae: Brevipalpus: B. lewisiMcGregor, 1949; B. obovatusDonnadieu, 1875; B. olearius Sayed, 1950; Cenopalpus: C. ruber Wainstein, 1960; C. meyerae Khosrowshahi, 1991; Tetranychidae: Panonychus citri(MaGregor, 1916); Oligonychussp.; Tetranychus urticaeKoch, 1836; Tuckerellidae: Tuckerella japonicaEhara, 1975.
