MALE. Unknown.

Remarks. Anoplocheylus marivaniensis sp. nov. closely resembles A. tauricus Livshitz and Mitrofanov, 1973 in having setae sc1 (sensillae) simple, five pairs of simple setae on the prodorsal shield, d3 and f1 the longest hysterosomal setae, and lengths of anal setae (ps1 and ps2) subequal, but it differs from the latter by: (1) coxal field I with four setae in the new species instead of three setae in A. tauricus , (2) basifemora I with eight setae vs. six in A. tauricus , (3) one pair of extra setae between setae f2 and h1 with one pair of extra setae opposed to absent in latter. The new species also is similar to A. aegypticus Baker & Atyeo, 1964 but can be readily distinguished from latter by: (1) lengths of pseudanal setae subequal [ps1 (28-33) and ps2 (34-37)] in the new species instead of ps1 (28–35) shorter than ps2 (41–54) in A. aegypticus , (2) basifemora I with eight setae instead of six setae in A. aegypticus , (3) one pair of extra setae between setae f2 and h1 opposed to absent in A. aegypticus .

Etymology. This species is named after the type locality, the city of Marivan.

Type materials. Holotype females and two paratype female from soil & rotten leaves of oak trees, Quercus brantii Lindl. , and four paratype females from soil under Crataegus pontica L ( Rosaceae ), Marivan vicinity, Kurdistan province, (35° 26' N, 46° 13' E, 1320 m a.s.l.), 13 Apr. 2013; coll. Fatemeh Amini. The type materials are slide mounted specimens. The holotype female and five paratype females are deposited in the Acari collection of the Department of Plant Protection, Faculty of Agriculture, University of Bu– Ali Sina, Hamedan, Iran and one paratype female will be deposited in the Arachnida Collection of ARC–Plant Protection Research Institute, Pretoria, South Africa.

Remarks. The new species is unique in the genus Anoplocheylus by having prodorsal sensillae (sc1) plumose in shape, but it does resemble A. paraclavatus Van Dis and Ueckermann, 1991 in having five pairs of setae on prodorsal shield, but differs from the latter by: 1) setae sc1 plumose in new species but claviform in A. paraclavatus ; 2) telofemora I with six setae instead of five setae in A. paraclavatus ; 3) tarsi I–IV with 18(ω) –7(ω) –9–9 setae in A. qorvehiensis but 19(ω)-7(ω)-7- 7 in A. paraclavatus .

Etymology. This species is named after the type locality Qorveh.

Type materials. Holotype female and one paratype female from Qorveh vicinity, Kurdistan province, soil under Astragalus sp. bushes, (47° 47' 06.33'' N, 35° 09' 03.62'' E, 1472 m a.s.l.), 20 March 2013; coll. Fatemeh Amini. The type material are slide mounted specimens. The holotype female deposited in the Acari collection of the Department of Plant Protection, Faculty of Agriculture, University of Bu-Ali Sina, Hamedan, Iran and one paratype female will be deposited in the Arachnida Collection of ARC–Plant Protection Research Institute, Pretoria, South Africa.
