Male: Unknown

Remarks. Cyta kurdistanicus sp. nov. is similar to C. latirostris ( Hermann, 1804) [re-described by Atyeo (1960)] in having broken striae on the dorsum, an unpaired seta (ms) between coxa IV, only tibia IV with a trichobothrium, palp genu with four setae, ovipositor with 20 setae but it differs by having: 1) telofemur IV with three setae in the new species but 4–6 setae in C. latirostris , 2) trochanter I with one seta instead of two; 3) coxa IV with three setae instead of two; 3) aggenital seta ag 2 long and extending past base of setae next behind (ag 3) in C. kurdistanicus opposed to shorter in C. latirostris ; 4) tarsi I–IV with 28t – 26t – 22t – 23t opposed to (21–24t)–(19–20t)–(16–19t)–(12–15t).

Etymology. This species is named after locality, Kurdistan province, which where collected type materials of this species.

Type material. The holotype and four paratype females were collected from soil covered with grass and litter under wild almond, Amygdalus lycioides Spach ( Rosaceae ), along Sirvan river, Palangan village, Kurdistan Province, Iran, (35 °03.7'N, 46 ° 35.97 'E, a.s.l. 864 m), 14.IV. 2013, by Amir Hossein Eghbalian. The holotype and three paratype females are deposited in the Collection of the Acarology Laboratory, University of Bu–Ali Sina, Hamedan, Iran. One paratype female will be deposited in the National Collection of Arachnida, Plant Protection Research Institute, Pretoria, South Africa.
