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 .
