(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.
