(Female): a – Leg I, b – Leg II, c – Leg III, d – Leg IV. Gnathosoma ( Figs. 1 b-c) — Chelicerae with proximal components completely fused in midline, forming bullet-shaped stylophore; peritremes confined to dorsal surface of stylophore, with 24–26 chambers on each side (Fig. 3). Palpi five segmented, palp tarsus distally with four eupatidia + one solenidion 5 (4 – 5) long + three setae, palp tibia with three setae and one small claw 6 (5 – 6); palpgenu and palpfemur each with one seta ( Fig. 2 ). Subcapitular setae m 35 (34 – 36), n 13 (13 – 15) long, adoral setae or1 10 (9 – 10), or2 11 (9 – 10); m–m 30 (28 – 35), n–n 12 (12 – 14) and m–n 18 (18 – 20), or1– or1 20 (19 – 20), or2–or2 18 (20 – 21), or1–or2 8 (7 – 9) ( Fig.2 ). Venter ( Fig. 1d ) — Ventral surface striated and three pairs of simple setae present, 1a located on coxae I but 3a and 4a located on integument, genital valves without seta, and aggental region with three pairs of setae ( ag1–3 ), one pair of cupules ( ih ) located lateral to setae ag2 (Fig. 4). Length of ventral setae as follows: la 28 (30 – 31), 1b 25 (23 – 26), 1c 27 (24 – 26); 2c 19 (18 – 20), 3a 28 (28 – 29), 3b 20(17 – 21), 4a 22 (20 – 21), 4b 21 (20 – 22), ag1 22 (21 – 24), ag2 16 (17 – 18), ag3 14 (13 – 15).

Legs ( Figs. 2 ) — Leg measurements are from coxa to pretarsus; leg I 280 (270 – 285); leg II 212 (210 – 215); leg III 220 (212 – 226), leg IV 253 (245 – 250); Setal formulae of leg segments as follows: coxae 3-1-2-1; trochanters 1-1-1-1; femora 2-2- 2-2; genua 5+1 κ -5-2-2; tibiae 5+1 ’ +1 ’ρ -5-4-4; tarsi 15+1 ω -11+1 ω - 9 - 9 (Figs. 5-8). Outer solenidion of tibia I ( ’ρ ) 11 (10 – 11) twice as long as inner solenidion ( ’ ) 5 (4 – 5); solenidion on tarsus I 10 (10 – 11), solenidion on tarsus II 10 (10 – 10). Differential diagnosis — Caligonella saboorii n. sp. resembles C. haddadi and C. humilis by having the same leg setal formulae but differs from C. haddadi by three main characters: (1) the length of dorsal setae in new species (17 – 26) longer than those C. haddadi (14 – 17); (2) the outer solenidion of tibia I two times as long as inner solenidion in C. saboorii n. sp. instead of three times longer than inner solenidion in C. haddadi ; (3) the outer solenidion on tibia I (10 – 11), solenidion on tarsus I (10 – 11) and solenidion on tarsi II (10 – 10) are equal in length in new species whereas outer solenidion on tibia I (15 – 16), longer than solenidion on tarsus I (11 – 12) and solenidion on tarsus II (10 – 10) in C. haddadi . The new species shares with C. humilis the identical setal formulae of legs and one pair of pseudanal setae but can readily be distinguished from the latter by: (1) the length of dorsal setae in new species (17 – 26) longer than those C. humilis (13); (2) the outer solenidion on tibia I and solenidion on tarsus I are equal in length versus outer solenidion on tibia I shorter than solenidion on tarsus I in C. humilis ; (3) The solenidion on tarsus I and solenidion on tarsus II are equal in length in the new species whereas two times longer than on tarsus II in C. humilis . Type materials — The holotype female and three paratype females were collected from soil and litter under Walnut tree, Juglans regia L. ( Juglandaceae ) in Khorramabad vicinity Lorestan province ( 33°56’N , 48°39’E , a.s.l. 1703 m ), 8 July, 2012, by Mohammad Ahmad Hoseini. The holotype female and two paratype females are deposited in the Collection of the Acarology Laboratory, University of Bu- Ali Sina , Hamedan , Iran . One paratype female, will be deposited in the mite Section of National Collection of Arachnida, Plant Protection Research Institute, Pretoria, South Africa . Etymology — This species is named in honor of Prof. Alireza Saboori, Department of Plant Protection, College of Agriculture, Tehran University, Karaj, Iran .
