Abstract A new species of the genus Storchia, S. elhamae sp. nov. is described and illustrated based on females collected from grass litters in Mahabad countryside, western Azerbaijan province, Iran. A key to all known species of the world is provided. Key words: Mite, predatory mites, tree, stored product, specimen
Introduction The genus Storchia is one of the smallest genera of the family Stigmaeidae. They live in soil, litter, moss, tree bark, house dust and stored products (Fan & Yan, 1997; Miranda et. al. 2002; Doğan & Ayyıldız, 2003; Noei et al. 2007; Palyvos et al. 2008; Safasadti & Khanjani, 2010). Up to present, nine species of the genus was reported, namely: S. robustus (Berlese, 1885); S. hendersonae Fan & Zhang, 2005; S. shanghaiensis (Liang & Hu, 1988); S. annae Fan & Li, 1993; S. cuneata Fan & Yan, 1997; S. pacifica (Summers, 1964); S. ardabiliensis Safasadati & Khanjani, 2010; S. yazdaniani Bagheri et al. 2011; S. mehrvari Bagheri et al. 2012. According to the references one third of all known species were recorded from Iran. In this paper the tenth species of the genus is presented.
Materials and methods Type materials of were collected from grass litter in Mahabad vicinity (36° 51′ 12′′ N, 45° 17′ 13′′ E, 1433 a.s.l.), west Azerbaijan province and were extracted by using a Berlese funnel. The collected mites were mounted directly in Hoyer’s medium on glass slides and then dried in an oven at 50°C for 10 days. The specimen was examined under an Olympus BX51 phase contrast microscope. Drawings were made with a camera Lucida. The terminology and setal notations used in the description of the new species follow that of Lindquist (1985). All measurements are given in micrometers (µm).

Discussion—Storchia elhamae sp. nov. resembles S. hendersonae Fan & Zhang (2005) in having the same leg chaetotaxy, however differs from that in: 1. prodorsal shield reticulated in the former opposed to smooth in the latter; 2. lengths of setae v1 16, v2 40, sc2 22, c1 14, d1 18, d2 20, e1 18, e2 21, f 17, h3 18, 3a 43 vs. v1 24, v2 56, sc2 37, c1 28, d1 26, d2 31, e1 26, e2 31, f 30, h3 25, 3a 68. The new species also resembles S. mehrvari Bagheri & Ghelealivand, 2012 in having the same prodorsal pattern and setal formulae of tibiae, and tarsi, however, it differs from the latter in: 1. Trochanter III with 1 seta instead of 2, 2. setae h1-2 on striated area versus on the smooth shield, 3. ventral seta 3a shorter than the later, 4. with 2 pairs of genital setae instead of 4 pairs. Etymology—This species is named in honor Mrs. Elham Jafarpour, wife of senior author. Material examined—Holotype female, 9 December, 2012 was collected from soil covered with grass, Mahabad vicinity, western Azerbaijan province (36° 51′ 12′′ N, 45° 17′ 13′′ E, 1433 a.s.l.), one paratype female as the same data of holotype. The holotype female is preserved as slide mounted specimen and deposited in the Collection of Acarology Laboratory, University of Bu-Ali Sina, Hamadan, Iran and one female paratype will be deposited in the mite Section of National Collection of Arachnida, Plant Protection Research Institute, Pretoria, South Africa.
