Subcapitulum 425 (462–500) long, width at base 225 (200–250); base of subcapitulum with broken and transverse striae, hypostome smooth; palp five–segmented, palp tibiotarsus with 14 setae [DES and VES 203 (215) and 173 (200) respectively]; genu with four setae; telofemur with one seta; basifemur with seven setae; trochanter lacking setae; measurements of palp segments: trochanter 15 (13), basifemur 290 (355), telofemur 45 (55), genu 55 (53), tibiotarsus 305 (310). Subcapitulum with six pairs of setae (vh1–6), distal pair (vh6) 75(88) more than twice length of proximal pair (vh1) 33 (35); two pairs of short adoral setae near tip of hypostome, avs 28 (30) and ad 19 (21). Cheliceral length 443 (425–433), width 95 (100–105), with 21 smooth setae (ch1–21), distal setae [ch1] 98 (75) and proximal setae [ch21] 38 (50), and; movable digit longer than fixed digit, movable chelae with two teeth and fixed digit smooth; distal seta (ch1) long extending to base of chela (Fig. 12).
Venter (Fig. 13). Aggenital region with three pairs of setae (ag1–3), each genital plate with ten pairs of setae (g1–10) (Fig. 13); anal region with three pairs of smooth setae (ps1–3): ps1 65, ps2 63 and ps3 broken.

Remarks. Neomolgus iraniensis Eghbalian, Khanjani, Safaralizadeh and Ueckermann sp. nov. is closely related to N. pygmaeus Shiba (1969) in having four setae on the papal genu, coxa I with five setae and telofemora II-IV with 7–6–6 setae but differs from the latter in having: 1) Dorsal setae smooth in N. iraniensis opposed to plumose in N. pygmaeus; 2) each chelicera with 21 setae in new species while eight setae in N. pygmaeus; 3) papal basifemur with seven setae in the former while four setae in the latter; 4) palp tibiotarsus with 14 setae in the new species opposed to nine setae in the latter; 5) each genital plate with ten setae vs eight setae; 6) Coxae II-IV with 3– 4–2 vs 4–3–3.
Neomolgus iraniensis Eghbalian, Khanjani, Safaralizadeh and Ueckermann sp. nov. is closely related to N. longipalpus Kuznetsov (1984) in having 7–6–6 setae on telofemora II-IV and coxa III-IV with 4–2 setae but differs from the latter in having: 1) each chelicera with 21 setae in the new species instead of 16 (17) setae in N. longipalpus; 2) palp basifemur with seven setae versus 19 setae; 3) palp genu with four setae versus ten setae; 4) palp tibiotarsus with 14 setae versus 27 setae; 5) coxa I-II with 5–3 setae versus 6–4 setae; 6) basifemura I-IV with 11–10–10–6 setae versus 22–17–15–8 setae; 7) telofemur I with seven setae instead of eight setae.
Etymology. The specific epithet is derived from Iran, due to the country where the new species was collected.
Type material. The holotype and two paratype females were collected from soil and litter under wild almond trees, Amygdalus scoparia L. (Rosaceae), "Sirvan river bank", located in Palangan village, Kamyaran, Kermanshah Province, Iran, (35° 03.7' N, 46° 35.97' E, a.s.l. 864 m), 14 IV 2013, by Amir Hossein Eghbalian. The holotype and one paratype females (EHBN 15014 and EPBH 15015, respectively) are deposited in the Mites Collection of the Acarology Laboratory, University of Bu–Ali Sina, Hamedan, Iran, and one paratype female slide will be deposited in the National Collection of Arachnida, Plant Protection Research Institute, Pretoria, South Africa.
