Turanobius hissaricus sp. n.

( Figures 7 , 16, 17 , 21 )

Type material. Holotype ♂ ( ZMMU), TAJIKISTAN: Region of Republican Subordination : Hissar Mts., Romit State Nature Reserve, 1.5 km W of Soni Vill., 38.833333°N, 69.433333°E, 1750 m, 5 July 2019 (S.L. Zonstein).

Etymology. The specific epithet refers to the type locality of the new species in the Hissar mountain range.

Diagnosis. The male of the new species differs from those of the congeners by the arms of radix wide and sharply pointed, with the mesal one longer than the prolateral one (vs arms thin, or blunt, or equal in size, or mesal one shorter; see Figures 9 , 15, 17, 19 ).

Description. Male. Habitus as in Figure 7 . Total length 2.88. Carapace 1.05 long, 1.30 wide. AME 0.10, ALE 0.11, PME 0.11, PLE 0.07. Carapace, sternum, chelicerae, labium and maxillae light yellowish beige; carapace with faint dark markings medially. Legs coloured like carapace, with distinct dark greyish annulations. Abdomen dorsally mottled with white guanine spots and dark brown median pattern and scattered patches and stripes, ventrally light beige with black markings posterolaterally. ALS and PLS dark greyish dorsally and pale beige ventrally, PMS uniformly pale beige. Measurements of legs: I: 4.46 (1.25, 0.43, 0.97, 0.98, 0.83), II: 4.63 (1.26, 0.46, 0.98, 1.09, 0.84), III: 4.90 (1.30, 0.43, 1.08, 1.22, 0.87), IV: 4.90 (1.39, 0.34, 1.16, 1.19, 0.82).

Palp as in Figures 16, 17 , 21 ; radix with broad wide finger-like arms of almost same length; prolateral loop of spermophor ca. 1.67 times longer than wide.

Female. Unknown.

Distribution. Known only from the type locality in Romit State Nature Reserve, western Tajikistan ( Figures 35, 36 ).
