Diagnosis

In possessing a gently twisted embolus, the male holotype of R. kirgizica sp. nov. resembles males of R. kopetdaghensis , R. mikhailovi and R. virgata . It can be distinguished from the former species in the presence of PMS (vs their absence in R. kopetdaghensis ) and from the two latter species in possessing a noticeably longer tibia and metatarsus I ( Fig. 280 View Figs 274–281 cf. Figs 282–283, 286–287 View Figs 282–289 ); the detailed structure of the embolus also looks different ( Figs 441–442 View Figs 439–447 cf. Figs 443–446 View Figs 439–447 , 454–458 View Figs 448–456 View Figs 457–465 ). The only known female (paratype) is distinguishable due to a specific conformation of the paired spermathecae, which are so small and thin, and so widely spaced from each other, that they can be reliably distinguished from the spermathecae in all other species of this group ( Fig. 537 View Figs 537–554 cf. Figs 334–536 View Figs 334–348 View Figs 349–363 View Figs 364–378 View Figs 379–388 View Figs 389–399 View Figs 400–408 View Figs 409–417 View Figs 418–428 View Figs 429–438 View Figs 439–447 View Figs 448–456 View Figs 457–465 View Figs 466–474 View Figs 475–486 View Figs 487–503 View Figs 504–521 View Figs 522–536 , 538–554 View Figs 537–554 ).

Etymology

The specific epithet is a toponym referring to the range of this species: Kyrgyzstan (also Kirgizia).

Ecology

The spiders were found under stones in sparse montane forest, dominated by Juniperus spp. (chiefly, by J. turkestanica Kom. and J. seravschanica ). The landscape and the natural biotope of the type locality is shown in Figs 717–718 View Figs 715–722 .

Distribution

Known only from the type locality. See Fig. 756 View Figs 751–760 .
