Ant. IV with about 40 ordinary chaetae, 7–8 short and truncate chaetae in ventro-apical part and 6 distinct subcylindrical sensilla; dorsoexternal microsensillum and subapical organite present; apical vesicle trilobed (Figs 13, 14).

Styliform maxilla with two lamellae, one of them with tiny apical hook (as on Fig. 9). Labral formula: 4/2,3,4 (as on Fig. 5a). Labium without organites x and papillate chaetae L, with 11+11 ordinary chaetae (Fig. 15). Perilabial area with 4+4 subequal chaetae.

Dorsal chaetotaxy as in Fig. 12 with very short chaetae and with short sensory S-chaetae. Formula per half tergum as: 022/11111. Microsensilla ms on Tht. II and III present. Head with unpaired chaeta d 1 and without chaeta a 0. Tht. I with 3+3 chaetae. Tht. II and III with 10+10 chaetae (a 1, a 4, a 6, m 5, m 6, p 1, p 2, p 4, p 5 and p 6 chaetae present), S-chaeta = p 4 and m 6. Abdt. I–III with 8+8 chaetae (a 1, a 4, a 6, p 1, p 2, p 4, p 5 and p 6 present), S-chaeta = p 5. Abdt. IV with 9(10)+9 chaetae (a 1, a 3, a 5, a 6, [m 6±], p 1, p 2, p 4, p 5 and p 6 present), S-chaeta = p 5. Abdt. V with 5+5 chaetae (a 1, a 3, p 1, p 3, and p 4 chaetae present), S-chaeta s = p 3.

Ventral chaetotaxy on Abds. I–VI as in Fig. 19. Thoracic sterna without chaetae, VT with 3+3 chaetae. Abds. I without chaetae, Abds. II with 4+4 chaetae, Abds. III with 6+6 chaetae.

* 1—simple, 2s—slightly bilobed, 3—trilobed. ** Tht. II and III with 10+10 chaetae each.

Dens with six chaetae (Fig. 18). Mucro boat-shaped, with curved ventral edge and one broad lateral lamella. Manubrium with 12+12 chaetae. Tenaculum with 3+3 teeth. Each anal valve with two chaetae hr (Fig. 19).

Tibiotarsi of legs I, II and III with 18, 18 and 17 chaetae, respectively, chaetae M and B7 absent on tibiotarsus III (Fig. 17). Femora I, II and III with 13, 12 and 11 chaetae, trochanters I, II and III with 6, 6 and 6 chaetae, coxae I, II and III with 3, 6 and 7 chaetae, subcoxae 2 of legs I, II and III with 0, 2 and 2 chaetae, subcoxae 1 of legs I, II and III with 1, 2 and 2 chaetae, respectively. Claw with a strong tooth near middle of inner edge and without lateral teeth in basal part (Fig. 17). Empodial appendage absent.

Etymology. The name of the new species refers to the Kurdistan Province (Iran), the place where the type specimens were collected.

Discussion. The same type of chaetotaxy of head (present unpaired chaeta d 1 and absent a 0 chaeta), Tht. I (3+3 chaetae), Tht. II-III (10+10 chaetae each, a 2 chaeta absent), Abdt. I-III (8+8 chaetae each, m row chaetae absent), Abdt. IV (9+9(10) chaetae, [m 6±]), Abdt. V (5+5 chaetae, a 2 and p 2 chaetae absent) and furca (six chaetae), the absence of lateral teeth on claws indicate a close relationship between P. kurdistanicus sp. nov., P. vasylii Kaprus’ & Weiner, 2009 and P. laricis Arbea & Jordana, 1989 . These species differ distinctly in number of vesicles in PAO, shape of apical vesicle on Ant. IV, details of labium chaetotaxy, labral formula of chaetae, number of chaetae on VT and tibiotarsi of legs I-III (Table 1).
