Figs 7–9, 14–15, 18, 25–27, 34–36, 41–42, 49–51, 56–59, 63–65, 68–72

Type material. KYRGYZSTAN: Osh Region: holotype ♂ (ISEA, 001.9557), Trans-Alay Mountain Range, 2 km ESE of Bardobo border outpost, 39°29.894’N, 73°17.455’E, large boulder scree with snow, 4100 m, 17.VII.2024, A.A. Fomichev; paratypes: 2♂ (ISEA, 001.9558), 1♀ (ISEA, 001.9559), 3♂ (ZMMU) together with the holotype .

Etymology. The specific name is derived from Trans-Alay Mt. Range, adjective.

Diagnosis. The male of P. transalaica sp. nov. differs from those of all congeners, except P. archalturica sp. nov. by unmodified tip of cymbium (cf. Figs 8, 15, 18 and 2, 11, 16, Fomichev et al. 2024: figs 5, 7, 9). The male of the new species can be distinguished from that of P. archalturica sp. nov. by a semicircular retrolateral process of tegular apophysis (RP) (vs. hook-shaped; cf. Figs 50 and 47) and by distal part of embolus (DE) lacking a cone-shaped process, with its apical part making two complete loops (vs. DE with cone-shaped process and shortened and hooked tip of embolus; cf. Figs 40 and 42). The female of P. transalaica sp. nov. differs from that of P. alaica sp. nov. by a trapezoidal fovea (Fo) (vs. triangular; cf. Figs 57–59 and 53–55) and by converging heads of receptacles (RH) (vs. parallel; cf. Figs 63–64 and 60–61). The female of the new species can be distinguished from that of P. kudratbekovi by circular posterior part of the receptacles (Re) (vs. screw-shaped; cf. Figs 63–65 and Fomichev et al. 2024: figs 36–38). For a more detailed list of differences between P. transalaica sp. nov. and other Pamirosa species see Table 11.

Clypeus height at AME 0.14. For legs measurements see Table 7. For legs spination see Table 8.

Male palp as shown in Figs 8–9, 14–15, 18, 25–27, 34–36, 41–42, 49–51. Femur 2.7 times longer than tibia, with 3 dorsal and 2 prolateral spines. Patella 1.3 times longer than tibia, with 1 prolateral spine. Tibia 3 times shorter than cymbium, with 2 dorsal spines. Cymbium length/width ratio 1.5. Tip of cymbium wide and thick, unmodified. Subtegulum (St) ovoid in retrolateral view. Tegulum circular, length/width ratio 0.8. Retrolateral ridge (RR) slightly curved retrolaterad. Conductor (Cn) oval in ventral view. Prolateral outgrowth of tegulum (PO) with parallel lateral edges. Tegular apophysis (TA) extends 1/4 beyond conductor. Prolateral process of tegular apophysis (PP) almost rectangular in prolateral view. Retrolateral process of tegular apophysis (RP) semicircular. Proximal part of embolus (PE) almost circular, with slightly indented retro-posterior margin. 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 11.0. Carapace: 4.5 long, 3.6 wide. Opisthosoma: 6.25 long, 4.05 wide. General appearance as in Fig. 56. Coloration as in male, but cardiac mark less contrasting. Eye sizes and interdistances: AME 0.10, ALE 0.19, PME 0.43, PLE 0.36, AME–AME 0.17, AME–ALE 0.13, PME–PME 0.39, PLE–PLE 1.21. Width of anterior eye row 0.93, 2 nd row 1.09, 3 rd row 1.53. Clypeus height at AME 0.20. For legs measurements see Table 9. For legs spination see Table 10.

Epigyne and internal genitalia as shown in Figs 57–59, 63–65. Fovea (Fo) trapezoidal, 3 times wider than long. Copulatory ducts (CD) not touching each other, form approximately 2 turns around fertilization ducts (FD). Posterior part of receptacles (Re) circular. Heads of receptacles (RH) kidney-shaped, converging.

Distribution. Known only from the type locality (Figs 71–72).
