( Figures 5D , 6G )

Material studied

Holotype female, collected from underneath Alhagi camelorum Fisch., Razan (Hamadan) , Iran, 27 August 1998, M. Khanjani.; 1 paratype female, Medicago sativa L, Shabestar (East Azerbaijan), Iran, 30 June 2006. P. Lotfollahi; 1 paratype female, soil, Najafābād (Esfahan), Iran, 30 March 2002, M. Jalaeian; 1 paratype female, Medicago sativa L (Alfalfa), Sonqor (Kermānshāh), Iran, 12 September 2003, M. Khanjani.

Diagnosis

This species very strongly resembles P. glebulentus Den Heyer, 1979 by also possessing a dorsal shield with transverse lobes. It differs, however, in the following aspects: ventral hypognathal ornamention of papillae and striae; genua I 3 asl (on one leg and 2 asl on the other leg),(1 asl,1 sts), 4 sts: genua II 2 asl, 5 sts; tarsus I 4 asl (on left leg) {3asl (on right leg)}, 1 famulus pit,1 dtsl, 2 tsl, 22 sts.

Female ( Figures 5D , 6G ) (n = 4)

Dimensions and description. Idiosoma: length 323 (319–327); width 204 (193–212); hypognathum: length 144 (139–154); width 117(92–142); length palp 96 (93–98); chelicera 139 (131–146); legs I 206 (193–212); II 179(166–193); III 201(193–216); IV 223 (212–235); sensillae vi, 119(115–123), sce 107(100–112).

Dorsum ( Figure 5 D–F). As in P. glebulentus , entire idiosomal shield provided with nearly transverse lobes ( Figure 5D ). Shield carries coarse setose sensillum pairs vi and sce ( Figures 5E, F ) as well as setae pairs ve, sci, c1, c2, d1, e1. Lyrifissures about halfway between setae e1 and f2. Setae ve, sci, e1 and h1 of about equal length; other setae somewhat shorter. Integumental striae lobed.

Venter ( Figure 5G ). Coxae II carry on their posteromedian edges a pair of propodogastral setae while coxae IV bear a pair of paracoxal setae on their median edges. Integumental striae consist of long broken lobes.

Gnathosoma ( Figure 6 A–C). Very well sclerotized. Length ratio gnathosomal coxal region: hypostome 1 or less.

Hypognathum ( Figure 6A ). Ventral hypognathal coxal region posteriad to hg4 with striae; laterad and anteriad, to latter setae, with papillae. Long setae hg3, nearly reaching hg2, placed posteriad off edge of palpal attachment.

Palp ( Figure 6B ). Resembles that of P. franciscae Den Heyer,1981 . Proximal part of medial surface papillate.

Chelicerae ( Figure 6C ). Typical for genus. Proximal part of dorsal surface papillate.

Legs ( Figure 6 D–G). Leg chaetotaxy: coxae I–IV 3 sts, 1 peg – 2 sts (+ 1 ppgs) – 3 sts – 2 sts (+ 1 pcs); trochanters I–IV 1–1–2–1 sts; basifemora I–V 4–6–3–2 sts; telofemora I–IV 5sts –5sts –3sts, 1 ms –2 sts, 1 ms; genua I–V 3 or 2 asl, (1 asl,1 sts), 4 sts–2 asl, 5 sts –1 asl, 5 sts –1 asl, 5 sts; tibiae I–IV 1 asl, 5 sts–1bsl, 5sts –1 bsl, 5 sts – 4 sts, 1 long T; tarsi I–IV 4 asl (on left leg) and / or 3asl (on right), 1 famulus pit, 1 dtsl, 2 tsl, 22 sts–1 bsl, 1 dtsl, 1 tsl, 19 sts–1 tsl, 17 sts –17 sts.

Male. Unknown.

Etymology

This species is named after the town Razan, where this species was collected.
