( Figures 1 ?10)

Diagnosis. Dorsal shield with 28 pairs of pilose setae, z1 short, pilose and not reaching base of j2; ventral shields with pilose setae except smooth para-anal setae.

Material examined. Holotype: Female, Karaj, Shahrestanak, O. Joharchi coll., 18 September 2009, 35˚56’ N, 51˚22’ E, alt. 2330 m, in soil. Two paratype females, Taleghan, Kalaank village, M. Keshavarz Jamshidian coll., 26 May 2013, 36 05´N, 50°29´E, alt. 1377 m, in soil.

Description. Female.

Dorsal idiosoma ( Figure 1 ). Dorsal shield oblong, length 913?965, width 495?557, surface punctate-reticulate over whole surface, shield bears 28 pairs of pilose setae and 22 pairs of pores (including 15 pairs lyrifissures and seven pairs of gland pores), seta z1 short and not reaching base of j2. Measurements of setae: j1 42–50, z 1 17–20, z5 25, z6 27, j5 37, j 6 30–37, J 2 27–32, J 5 21–22, Z5 35–37. Distance between setae z1 and j2 about 27.

Ventral idiosoma ( Figure 2 ). Tritosternum typical for family, with pilose paired laciniae and a base that is longer than wide. Sternal shield ( Figure 7 ) length 173–178, width 181–198, ornamented with polygonal patterns and punctations, bearing pilose st1–st3 and iv 1–2. Metasternal platelets oval, free, each bearing a pilose seta st4 and an anterior pore iv3. Length of epigynal shield 205?210, width 131–156, surface of the shield with lines bordered by fine punctation ( Figure 8 ), iv 4 in soft cuticle. Three pairs of small sclerites present between epigynal and ventrianal shields. Ventri-anal shield ( Figure 9 ) length 262–317 and width 223?262 (at widest point, L/W=1.2), longer than wide and ornate with lines and fine punctation, with three pairs of pilose pre-anal setae (27–30), a pair of smooth para-anal setae and a pilose post-anal seta. Cribrum well developed, anterolateral extensions of cribrum reaching bases of anal setae. Metapodal platelets small.

Gnathosoma ( Figures 3–4, 6 , 10 ). Hypostomal setae smooth. Deutosternal groove ( Figure 4 ) with five transverse rows of denticles. Salivary styli conspicuous and flanked by corniculi. Epistome ( Figure 3 ) triramous; with a median bifid process, spiculate medially and fused lateral process bifurcated. Chelicerae ( Figure 6 , 10 ) robust, movable digit 89–99, with two larger proximal teeth and a minute sub distal tooth, middle segment 205– 210, fixed digit with three teeth, pilus dentilis and terminal hook, with a serrated dorsal seta. Arthrodial brushes pilose, longer brush more than half length of movable digit ( Figure 6 ). Chaetotaxy of palp trochanter, femur and genu 2–5–6. Palp apotele with 3 subequal teeth.

Legs. Leg length (except ambulacrum): leg I, 693?718, leg II, 608–643, leg III, 557?569, leg IV, 852?911; tarsus II as in Figure 5 . Genu IV with six pilose setae.

Sacculus foemineus . Obscure in available whole-mount specimens.

Etymology. This new species is named in honour of Prof. Alireza Saboori (Department of Plant Protection, University of Tehran, Karaj, Iran).
