Abstract
|
The superfamily Tydeoidea consists of four families: Triophtydeidae (syn.: Edbakerellinae of Andre, 2004), Ereynetidae, Tydeidae and Iolinidae. The mite superfamily Tydeoidea is worldwide in distribution, occurring from Antarctica to the tropics, from the seashore to alpine meadows, from the coldest areas to dry or hot deserts such as the Namib and the Chihuahuan. The Tydeidae as traditionally known includes free-living predators of rust mites, spider mites and others. Some of them are recorded as plant and fungus feeders, scavengers and some of them are prey of other group of predatory mites (e.g. the Phytoseiidae). During 2015, fauna of the superfamily Tydeoidea in Champir Village, Isfahan Province were collected and identified. The collected mites were directly mounted in a droplet of Hoyer’s medium, then covered with a coverslip, rolled under the microscope until an adequate position was found, and then dried prior to further study. In this study in total 13 species, belonging to 5 genera and 3 families were identified. Among them, 5 species belong to the family Iolinidae, 7 species belong to family Tydeidae and 1 species belongs to family Triophtydeidae. Identified species are listed as follow: Iolinidae: Neopronematus: N. sepasgosariani Sadeghi, Laniecka and Kazmierski, 2012; N. lundqvisti Sadeghi, Laniecka & Kazmierski, 2012; N. kamalii Darbemamieh & Hajiqanbar, 2015; Pronematus: P. ubiquitus (McGregor, 1932) McGregor, 1932; P. indiana Gupta & Paul, 1985; Tydeidae: Lorryia: L. obstinata Livshitz, 1973; L. vianensis Khanjani & Ueckermann, 2003; L. benensis Baker 1968; L. formosa Cooreman, 1958; Tydeus: T. caryae Khanjani & Ueckermann, 2003; T. caudatus Dugés, 1834; T. kochi Oudemans, 1928; Triophtydeidae: Triophtydeus immanis Kuznetzov, 1972. Lorryia vianensis was the dominant tydeoid mite species in this region, and Tydeus caryae was the subdominant one. Tydeus caryae, Tydeus caudatus and Tydeus kochi had clearly visible high population on walnut leaves which
