Remarks — Storchia yazdaniani n. sp. resembles to S. robustus but can be separated by: (1) – ve is very long, (115 – 122µm), and which can reach the posterior end of prodorsal shield (vs 55 – 62 µm in S. robustus); (2) – Humeral setae c2 long, (95 – 104 µm), and more than 3 times the length of c1 (vs 32 – 37 µm and 1.4 times length of c 1 in S. robustus); (3) – dorsal hysterosomal setae c1 nearly 1/4 distance of c1 – c1 (vs 1/3 distance c1 – c 1 in S. robustus); (4) ratio 1a: 3a: 4a = 1: 1.8: 1 (vs 1: 3.2: 1); (5) – ratio ag1: ag2: ag3: ag4 = 1: 1.4: 2: 1.1 (vs 1.5: 1.6: 2.7: 1).
Etymology — This species is named in honour of Dr. Mohsen Yazdanian, Gorgan University of Agricultural Sciences and Natural Resources and the friend of the first author
Type material — Holotype and 4 paratype females of S. yazdaniani n. sp. were collected from soil and moss, 9 May 2010, in Gorgan (Golestan Province, Iran) by Shiela Shirnbeik Mohajer. The holotype and 1 paratype females were deposited in the Arachnida Collection of Plant Protection Research Institute (Pretoria, South Africa); 2 paratype females were deposited in the Acarological Collection of the Department of Plant Protection, Faculty of Agriculture, University of Maragheh (Iran) and 1 paratype female was deposited in Jalal Afshar museum (Karaj, Iran).
