Diagnosis
Differs from the other two species of this group in having a distinctly developed dorsal abdominal pattern and an even longer apical segment of PLS. Males of R. redikorzevi can be distinguished from males of R. caudata and R. inopinata sp. nov. in possessing noticeably stouter though similarly long legs, closer spaced megaspines, a stouter palpal tibia and cymbium, as well as by details of the embolic keel and tip (see Figs 260 View Figs 256–264 , 351 View Figs 349–363 , 383–384 View Figs 379–388 , 466–468 View Figs 466–474 cf.

Variation
Carapace length in males (n=8) varies from 6.25 to 8.20. In some specimens, dorsal abdominal pattern may be noticeably darker and more contrasting than in the figured male and female.
Ecology
The species inhabits lowland semideserts, open low woodlands dominated by Pistacea vera L., and montane steppes ( Figs 623–626 View Figs 619–626 ); wandering males occur under rocks. According to the personal communication of R.E. Zlotin (Research Institute of Geography, Russian Academy of Sciences, Moscow), the specimens collected by him were captured when he investigated the abandoned burrows of xerophilic rodents (mostly, of gerbils, Meriones spp. ) and reptilians.
Distribution
South Turkmenistan: Badhyz Plateau, including its western mountainous border (Zulfagar Mts). Very likely, the species can also occur within the neighbouring territories of Iran and Afghanistan. See Figs 748–749 View Figs 747–750 .
Notes
Zonstein (2009) considered the only known conspecific female as an immature specimen (judging from its smaller size in comparison with the majority of collected males belonging to the same species). However, the dissection that followed the premature appreciation revealed that this relatively small female is nevertheless adult and possesses normally developed spermathecae.
