Abstract

Members of family Tenuipalpidae are phytophagous and some of their damages on the plant hosts are economically important. They feed directly from the epidermal cell and sub epidermal tissue, like mesodermalcells of the stems, leaves and fruits (Beard et al., 2012). This family comprises over 1,100 species in 38 genera. BrevipalpusDonnadieu, 1875 and CenopalpusPritchard and Baker, 1958 are two of the largest genera of Tenuipalpidae. GenusCenopalpus is more biogeographically restricted than Brevipalpus, being absent from the Nearctic and Neotropical regions, where the diversity of Brevipalpus is greatest (Mesa et al., 2009). To date, 7 species of Brevipalpusand 18 species of Cenopalpushave been recorded from Iran. During 2013-2014, a research was conducted on genera Brevipalpusand Cenopalpusin north and west of Iran. In this concern leaves of trees and grass clumps which were infested by false spider mites were collected and taken to the laboratory. Mites were removed from plant leaves with a No. 0 paint brush under a stereomicroscope (Wild M8) and directly mounted in Hoyer’s medium. In total, 13 species were identified, namely:BrevipalpusDonnadieu, 1875: B. lewisiMcGregor, 1949; B. obovatusDonnadieu, 1875; B. oleariusSayed, 1950 and B. phoenicis(Geijkes, 1939); Cenopalpus Pritchard and Baker, 1958: C. ruber Wainstein, 1960; C. meyerae Khosrowshahi, 1991; C. rubusi Khanjani et al., 2012;C. prunusiKhanjani et al., 2012;C. khosrowshahi Khanjani et al., 2012; C. bakeri Duzgunes, 1967; C. crataegi Dosse, 1971; C. iraniDosse, 1971; C. lanceolatisetae Attiah, 1956. Among them Cenopalpus irani and Cenopalpus bakeri were found abundantly and almost with wide distribution in these areas.
