Figs 1–3, 10–11, 16, 19–21, 28–30, 37–38, 43–45, 52–55, 60–62, 66, 71–72
Type material. KYRGYZSTAN: Osh Region: holotype ♂ (ISEA, 001.9171), Alay Mountain Range, Tengizbai Mountain Pass, 13 km NNW of Daroot-Korgon Village, 39°40.307’N, 72°10.309’E, scree, 3800–4200 m, 12– 13.VII.2024, A.A. Fomichev; paratypes 1♀ (ISEA, 001.9172), 1♀ (ISEA, 001.9173), together with the holotype.
Etymology. The specific name is derived from Alay Mt. Range, adjective.
Diagnosis. The male of P. alaica sp. nov. differs from all congeners except P. kudratbekovi in having the tip of cymbium bent dorsally (cf. Figs 2, 11, 16 and 5, 8, 13, 15, 17–18). The male of the new species can be distinguished from that of P. kudratbekovi by a Г-shaped tegular apophysis (TA) with ventrally-directed prolateral process (PP) in ventral view (vs. irregularly shaped TA with clearly prolateral-directed PP; cf. Fig. 44 and Fomichev et al. 2024: fig. 22). The female of P. alaica sp. nov. differs from those of P. kudratbekovi and P. transalaica sp. nov. by triangular fovea (Fo) (vs. trapezoidal; cf. Figs 53–55 and 57–59, Fomichev et al. 2024: figs 33–35) and by parallel heads of receptacles (RH) (vs. converging; cf. Figs 60–61 and 63–64, Fomichev et al. 2024: figs 36–37). For a more detailed list of differences between P. alaica sp. nov. and other Pamirosa species, see Table 11.
Description. Male. Total length 7.35. Carapace: 3.9 long, 3.0 wide. Opisthosoma: 3.45 long, 2.25 wide. General appearance as in Fig. 1. Coloration. Carapace dark brown. Eye field almost black. Clypeus, chelicerae, labium and sternum dark brown. Endites and coxae yellow brown. Palps brown, distal part of cymbium yellow. Legs brown, without annulations. Opisthosoma gray, with dark, brick-red colored cardiac mark. Spinnerets gray. Eye sizes and interdistances: AME 0.11, ALE 0.13, PME 0.37, PLE 0.31, AME–AME 0.14, AME–ALE 0.14, PME–PME 0.36, PLE–PLE 1.04. Width of anterior eye row 0.79, 2 nd row 1.01, 3 rd row 1.40. Clypeus height at AME 0.17. For legs measurements see Table 1. For legs spination see Table 2.
Male palp as shown in Figs 2–3, 10–11, 16, 19–21, 28–30, 37–38, 43–45. Femur 2.3 times longer than tibia, with 3 dorsal and 2 prolateral spines. Patella 1.2 times longer than tibia, with 1 prolateral spine. Tibia 2.5 times shorter than cymbium, with 2 prolateral spines. Cymbium length/width ratio 1.6. Tip of cymbium flattened, bent dorsally. Subtegulum (St) square in retrolateral view. Tegulum (Te) circular, length/width ratio 0.9. Retrolateral ridge (RR) straight. Conductor (Cn) triangular in ventral view. Prolateral outgrowth of tegulum (PO) with converging lateral edges. Tegular apophysis (TA) extends 1/4 beyond conductor. Prolateral process of tegular apophysis (PP) ventrally-directed, spine-like in prolateral view. Retrolateral process of tegular apophysis (RP) semicircular. Proximal part of embolus (PE) almost circular, smoothly rounded. Basoembolic apophysis (BA) with more developed posterior lobe (PL). Terminal apophysis (Tr) with clow-like tip. Dorsal process of embolic division (DP) trapezoidal in dorsal view. Distal part of embolus (DE) tightly twisted, making two loops.
Female. Total length 8.25. Carapace: 4.2 long, 3.0 wide. Opisthosoma: 4.45 long, 3.0 wide. General appearance as in Fig. 52. Coloration as in male. Eye sizes and interdistances: AME 0.10, ALE 0.14, PME 0.36, PLE 0.30, AME–AME 0.16, AME–ALE 0.17, PME–PME 0.40, PLE–PLE 1.10. Width of anterior eye row 0.86, 2 nd row 1.03, 3 rd row 1.43. Clypeus height at AME 0.19. For legs measurements see Table 3. For legs spination see Table 4.
Epigyne ant internal genitalia as shown in Figs 53–55, 60–62. Fovea (Fo) triangular, 3 times wider than long. Copulatory ducts (CD) touching each other, form approximately 2 turns around fertilization ducts (FD). Posterior part of receptacles (Re) screw-shaped. Heads of receptacles (RH) rode-shaped, parallel.
Distribution. Known only from the type locality (Figs 71–72).
