(Female): a – Leg I, b – Leg II, c – Leg III, d – Leg IV. Venter — ( Figure 1b ) Endopodal shields absent; setae 1a and 3a near coxae I and III respectively, setae 4a on membrane posterior to coxae IV; venter striated except for coxae; aggenital area with two pairs of aggenital setae ( ag1 – ag2 ); genital area with four pairs of setae ( g1 – g4 ); anal shield with three pairs of anal setae ( ps1 – ps3 ). Measurements of setae: 1a 33 (30), 3a 26 (27), 4a 22 (25), ag1 17 (20), ag2 18 (19), g1 16(16), g2 15 (16), g3 15 (15), g4 15 (15), ps1 15 (15), ps2 15 (17) and ps3 14 (16). Gnathosoma — Subcapitulum ( Figure 1c ) ventrally with two pairs of subcapitular setae ( m and n ), equal in length, m = n = 30, and 2 pairs of adoral setae ( or1 and or2 ) which are slightly serrated; distances between n - n 36, m - m 19, n - m 12. Dorsal stylophore with striae. Palpi ( Figure 1d ) five segmented; palptarsus with four setae, four eupathidia and one solenidion (ω); palptibia with three setae and one small claw; palpgenu and palpfemur each with two setae; palptrochanter without setae. Legs — ( Figure 2 ) length of legs I-IV (from base of coxae to tip of tarsal claw): 275(251) – 235(205) – 243(225) – 319(255). Chaetotaxy of leg segments as follows: coxae (excluding 1a , 3a and 4a ) 2-2-2-1, trochanters 1-1-2-1, femora 6-5-3- 3, genua 5+1κ-5+1κ-4-4, tibiae 5+1’-5+1’-5+1’ρ- 4+1’ρ, tarsi 19+1ω+1ωρ-16+1ω-13+1ωρ-13. Male and immature stages — Unknown. Etymology — The species is named in honor of Prof. Alireza Saboori (Professor of Entomology, University of Tehran , Iran ), for his great efforts to develop of Acarology in Iran . Type material — Holotype and 1 paratype female of Raphignathus saboorii n. sp. were collected from soil in apple orchards, 20 August 2009 , Maragheh, East Azerbaijan province , Iran , by Hamed Ghorbani. The holotype and paratype females will be deposited in the Arachnida Collection of Plant Protection Research Institute, Pretoria, South Africa . Remarks — The new species is very closely related to R. sceptrum Chaudhri, Akbar and Rasool ( Chaudhri et al. 1979 ) by having: 4 pairs of genital setae, 2 pairs of setae on interscutal membrane, 2 pairs of setae on palpfemur and simple dorsal setae but can be distinguished from the later as follows: 1. R. sceptrum has one pair of small shields behind the anteromedian propodosomal shield which are absent in new species. 2. setae f 1 in new species well behind the anterior margin of opisthosomal shield but in R. sceptrum f1 situated on anterior margin of opisthosomal shield. 3. tarsi I and IV with 21 and 13 setae in new species vs 19 and 12 in R. sceptrum, respectively. Raphignathus saboorii also resembles R. gracilis by having 2 pairs of interscutal setae, 2 setae on palpfemur, simple dorsal setae and absence of small shields on interscutal membrane but, can be separated by following features: 1. genital shields with 4 pairs of setae in R. saboorii vs . 3 pairs in R. gracilis 2. tarsus II with 17 setae vs . 16 in R. gracilis. 3. coxisternal III-IV is absent in new species but present in R. gracilis .
