Paurotyndareus Darbemamieh & Kazmierski n. gen. (Acari: Iolinidae: Tydaeolinae) is described and illustrated. The new genus can be separated from Tyndareus and near genera by reduced chaetotaxy of legs and genital region.This genus is characterized by double tip eupathidium at the end of palp, femur I with five setae, genu III with one seta, three pairs of genital and two pairs of aggenital setae. Paurotyndareus persicus Darbemamieh and Kaźmierski n. sp. collected from soil in Kermanshah, Iran is described as the type-species. Key words: mite, Tydeoidea, Tydaeolinae, taxonomy, Paurotyndareus persicus, Kermanshah Introduction The superfamily Tydeoidea (Acari: Prostigmata) contains a group of cosmopolitan, soft-bodied, striated or reticulated mites that have been recorded as predators, phytophagous, mycophagous and scavengers (Gerson et al. 2003; Kaźmierski 1998). Little is known about the ecological interactions between these mites and their habitats, and few have been categorized as to a general lifestyle (Walter et al. 2009). The Tydeoidea was reorganized by André & Fain (2000) and now contains 4 families: Triophtydeidae André, 1980, Ereynetidae Oudemans, 1931, Tydeidae Kramer, 1877 and Iolinidae Pritchard, 1956. The family Iolinidae containing 36 genera and 131 species is a taxon with high diversity of different characters based on dorsal and leg chaetotaxy, epimeral formula and palpal chaetotaxy (Ripka et al. 2013; Sadeghi et al. 2012; Theron et al. 2012; Zhang et al. 2011). Livshitz and Kuznetzov (1972) described the genus Tyndareus. According to their description, the prodorsum is procurved, opisthosoma with 11 pairs of dorsal setae (without pseudo-anal setae) and four pairs of lyrifissures, six pairs of genital and four pairs of aggenital setae, epimeral formula: (3-1-4-3), legs chaetotaxy (tarsus-trochanter): I (10 or 12-5-4-5-1), II (8-2-4-4-1), III (7-2-2-3-1), IV (7-2-1 or 0-2-0); (it) is missing or not on tarsus I; eupathidia on tarsus I: ft'', (tc), (p);
