(Figs. 1–7)
Diagnosis. Dorsal shield distinctly reticulated with a strip of reticular pattern between setae j6 and J2; with 9 pairs of small pores on dorsal shield; dorsal setae smooth except Z5 and J5 pectinate; setae Z3 absent; setae ST 3 set on platelets; peritremes extending to level of, or just passing, the bases of setae z2; calyx of spermatheca saccular with a c-shaped atrium; fixed cheliceral digit with 2 subapical teeth.
FEMALE. Two specimens measured: (Means followed by the respective ranges: bold figures, holotype; not bold, paratype)
Dorsum. Dorsal shield 363 (360– 365) long and 202 (200– 203) wide at j6 level; not strongly sclerotized, entirely reticulated with a strip of different reticulation between setae j6 and J2; 19 pairs of dorsal setae, 9 pairs of small pores on dorsal shield; all dorsal setae smooth except pectinate Z5 and J5; lengths j1 18 (17– 18), j3 27 (26– 28), j4 18 (16– 20), j5 17 (15– 19), j6 26 (24– 27), J2 26 (24– 28), J5 18 (17– 19), z2 28 (28 –28), z3 28 (27– 29), z4 30 (29– 30), z5 19 (18– 20), z6 25 (23– 26), Z4 35 (34 –35), Z5 49 (48– 49), s4 30 (29– 30), s6 33 (32– 33), S2 38 (37– 38), S4 40 (38– 41), S5 46 (46 –46); setae r3 25 (24– 26) and R1 25 (23– 26) on lateral integument.
Peritreme. Extending to level of, or just passing the bases of, setae z2 (Fig. 1).
Venter. Sternal shield smooth (paratype female with a vague v-shape pattern anteriomedially, Fig. 6), 37 (35– 39) long and 62 (61 –62) wide at level setae ST2, with 2 pairs of setae and 2 pairs of pores, setae ST3 located off shield on small platelets, setae ST4 and a pair of pores on metasternal shields, ST1 25 (24– 25), ST2 26 (25– 26), ST3 25 (24– 25), ST4 25 (24– 25); genital shield smooth, width 63 (62– 64) at widest level; setae ST5 21 (20– 22); paragenital pores located on integument between setae ST5 and ZV1; 4 narrow integumental platelets located between genital and ventrianal shield; 2 pairs of metapodal shields, primary platelet narrow, elongate and slightly curved, 49 (48– 50) long and 3 (2– 3) wide, and accessory platelet 14 (13– 14) long; ventrianal shield sole-shape, with a few striae at waist, length 127 (125– 128), width at level of setae ZV2 38 (31– 45), width at level of waist 29 (28– 30) and width at level of paranal setae 52 (49 –54); with 2 pairs of preanal setae (JV2 and JV3 absent) JV1 18 (17– 18), ZV2 17 (16– 18); 4 pairs of setae surrounding ventrianal shield on integument, ZV1 (22), ZV3 14 (13– 15), JV4 16 (15– 17), JV5 29 (28 –30) (Fig. 2).
Spermatheca. Calyx saccular 17 (16– 17) long with a c-shaped atrium (Fig. 3).
Chelicera. Fixed digit 22 (21– 22) long with 2 subapical teeth; movable digit 24 (24 –24) long with 1 tooth (Fig. 4)
Legs. Macrosetae on basitarsus IV 30 (29– 30) long; genua and tibiae I-II-III-IV with 10-8-7-7 and 10 -7-7-6 setae, respectively.
MALE. Unknown.
Locality and type material. Holotype female, pistachio tree, Borkhar (Isfahan Province), Iran, 7.iv.2003; Paratype female, apple tree, Naein (Isfahan Province), Iran, 12.viii.2003, collected by M. Jalaeian. Both specimens deposited in RMNH.
Remarks. With respect to the shape of the spermatheca, P. amacroporus is close to P. triporus (Chant & Yoshida- Shaul). However, the latter species has three pairs of large pores on the dorsal shield while those pores are absent in the new species. The new species also resembles P. p o ro s u s Kolodochka. In P. p o ro s u s, the spermatheca has a long neck, the peritremes extend to the level of setae j1 or between j1 and j3, and setae Z4 are pectinate while in P. amacroporus the spermatheca has no neck, the peritremes extend to the level of setae z2 or between z2 and j3, and setae Z4 are smooth.
Etymology. The epithet amacroporus refers to the absence of large pores on the dorsal shield as opposed to triporus (P. triporus), which has three pairs of large pores.
