Diagnosis
The new species shares with Raveniola afghana sp. nov., R. alajensis sp. nov. and R. hirta sp. nov. the presence of the modified long hairs on the female tibia and metatarsus IV. Females of R. karategensis sp. nov. can be distinguished from those of R. afghana and R. hirta by having a fuzzily ornamented (vs uniformly coloured) abdomen (see Fig. 44 View Figs 36–44 cf. Figs 37, 42 View Figs 36–44 ), and from females of R. alajensis in possessing a less pronounced abdominal pattern and the distinctly configured spermathecae with wider bases, broadly spaced stalks and clearly wider inner branches ( Figs 44 View Figs 36–44 , 510–512 View Figs 504–521 cf. Figs 38 View Figs 36–44 , 491–493 View Figs 487–503 ).
Etymology
The specific epithet is a toponym referring to the range of this species, confined to the historical area Karategin (also Karategen), an eastern province of the Bukhara Emirate in the 19 th century, which included the Karategin Mts and Peter I Mts.

SPERMATHECAE. Each of paired spermathecae U-shaped with a relatively low and wide base carrying two more or less broadly spaced and unevenly shaped branches: a longer and wider trapezoidal inner branch and a more slender, shorter and club-like outer one ( Fig. 510 View Figs 504–521 ).
SPINNERETS. See Fig. 576 View Figs 575–583 . PMS: length 0.89, diameter 0.36. PLS: length of basal, medial and apical segments 1.55, 0.73, 0.42; total length 2.70; apical segment triangular.

Unknown.
Variation
Carapace length in paratype females (n=7) varies from 6.71 to 7.88. All the examined females are habitually very similar to each other. Variations in the structure of the eye group, tibia and metatarsus IV, and the spermathecae as shown in Figs 177 View Figs 172–183 , 317 View Figs 310–318 , 511–512 View Figs 504–521 .
Ecology
The spiders were found in the midland zone at an altitude of 1900–2000 m a.s.l. inhabiting open woodland dominated by Juniperus seravschanica . Females of Raveniola karategensis sp. nov. live in open burrows of 30–40 cm depth, provided with a weakly silk-lined entrance rim, walls and living chamber ( Figs 659–666 View Figs 659–666 , 675, 678–679 View Figs 675–682 ).
Distribution
