MALE and immature stages. Unknown.

Material examined. Holotype female and 3 female paratypes collected from Poa bulbosa L. ( Poaceae ), IRAN: Hamedan Province, Nahavand, (34°02ʹN. 48°22ʹE, 1830 m. a. s. l.), 15 March 2011, coll. A. Nazari.

Type deposition. Holotype female, 2 female paratypes—CALBS; 1 female paratype—QMA.

Etymology. This species is named for Alireza Nazari, who collected the type specimens of the species.

Remarks. This species is distinctive by having fine dorsal setae and coarse irregular dorsal striae. In this regard, it resembles A. curtipilis Baker and Tuttle, 1987 , and A. lacida Baker and Tuttle, 1972 . It differs from the former by having coarse transverse striae on the ventral shield (versus longitudinal striae) and a striate genital shield (versus smooth). The new species differs from A. lacida by having irregular dorsal striae (versus mostly uniform), setae f2 almost level with e3 (versus well behind e3), and well-defined prodorsal projections (versus weak projections).
