Adult female (n = 1) Gnathosoma – Epistome with three prongs relatively equal length; palp apotele two-tined; fixed cheliceral digit 16 long, with a few small teeth; movable cheliceral digit 19 long, with three teeth; corniculi horn-like; hypostomal setae smooth, h1 14, h2 3, h3 10, pc 13.

Idiosoma – 240 long, 120 wide, smooth.

Dorsal idiosoma ( Fig. 8 View Figures 8–9 ) – Podonotal and opisthonotal shields separate, both smooth. Podonotal shield with 21 pair setae (j1–6, z1–6, s1–6, r2, r4–5), a pair of distinguishable lyrifissures (id1), two pairs of gland pores (gd1 and gd2) and four scleronoduli between setae j5 and j6, setae r3 are located outside the shield. Opisthonotal shield with 19 pairs of setae (J1 –5, Z1 –5, S1 –5, R2 –5 ), three pairs of distinguishable lyrifissures (idm1, idl3 and idl4) and a pair of gland pores (gd8) and setae R1 absent. Measurements of setae: j1 4, j2 6, j3 10, j4 10, j5 9, j6 8, z1 broken, z2 6, z3 9, z4 9, z5 10, z6 9, s1 6, s2 8, s3 8, s4 8, s5 8, s6 7, r2 7, r3 9, r4 7, r5 8; J1 9, J2 10, J3 10, J4 7 slightly thickened, J5 7, Z1 9, Z2 11, Z3 12, Z4 8 slightly thickened, Z5 16, S1 7, S2 7, S3 10, S4 11, S5 14, R2 8, R3 8, R4 10, R5 12. All setae short and smooth .

Ventral idiosoma ( Fig. 9 View Figures 8–9 ) – All ventral shields smooth. Sternal shield 72 long and 44 wide, with four pairs of setae, st1 10, st2 10, st3 11, st4 10 and two pairs of distinguishablelyrifissures (iv1, iv3) between St3-St4. Genital shield 40 wide, with a pair of setae st5 10, iv5 located on soft cuticle. Ventrianal shield rounded-triangular, length 80 and width 78; with four pairs of preanal setae, Jv1 8, Jv2 10, Jv3 10, Zv2 7 in addition to para-anal15 and, post-anal 7; Zv1 10, Zv3 10, Jv4 12, a pair of lyrifissures (ivo) and a pair of partially fused metapodal plates located on the soft cuticle of each side; peritremes extending anteriorly to posterior level of coxa I.

Material examined – Rasht County, Bijar Boneh village (37° 18' 21.0" N, 49° 38' 49.0" E), 1 May 2019, from greenhouse soil, one female GoogleMaps .

Remarks – Comparing the examined specimens with Barilo's (1989) description, idiosoma (240 vs. 220) long, (120 vs. 105) wide, J4 (8 vs. 6–7), Z3 (12 vs. 11.5), Z5 (16 vs. 17).
