( Figures 5, 6 View Figures 1–7 , 14, 15 View Figures 14–19 , 20 View Figures 20–22 , 29–34 View Figures 23–34 )
Type material. Holotype ♂ ( ZMMU), TAJIKISTAN: Khatlon Region: env. of Khuruson , 38.179056°N, 68.661694°E, clay cliff, 724 m, 3 May 2015 (Y.M. Marusik) GoogleMaps . Paratypes: 8♂ 1♀ ( ZMMU), same data as for the holotype; 1♂ ( MMUE), TAJIKISTAN: Khatlon Region: deep clay canyon on road from Pyandzh Town to Pyandzh Karatau Mt GoogleMaps . ridge, 37.298611°N, 69.159194°E, 430 m, 4 May 2015 (Y.M. Marusik).
Etymology. The specific epithet is a combination of the Greek terms lepto - (meaning ‘thin’) and - onychus (meaning ‘clawed’), referring to the shape of the extension of terminal apophysis of the male palp.
Diagnosis. The male of this species differs from the congeners by having thin and sharply pointed radical arms which are equal in length (see Figures 9 View Figures 8–13 , 15, 17, 19 View Figures 14–19 ). The female of T. leptonychus sp. n. can be distinguished from that of T. tadzhikus by the length/width ratio of the area formed between the insemination ducts (ca. 5, vs 3; see Figures 29, 23 View Figures 23–34 ).
Description. Male (holotype). Habitus as in Figure 5 View Figures 1–7 . Total length 2.37. Carapace 0.95 long, 1.03 wide. AME 0.08, ALE 0.10, PME 0.11, PLE 0.06. Carapace, sternum, chelicerae, labium and maxillae light yellowish beige; carapace with dark markings medially; sternum with dark greyish marginal bands. Legs coloured as carapace, with distinct dark greyish annulations. Abdomen dorsally mottled with white guanine spots and dark brown median pattern and scattered patches, ventrally light beige with black markings medially and posteriorly. ALS and PLS dark greyish dorsally and pale beige ventrally, PMS uniformly pale beige. Measurements of legs: I: 3.49 (0.95, 0.34, 0.74, 0.78, 0.68), II: 3.49 (0.96, 0.35, 0.77, 0.79, 0.62), III: 3.60 (0.99, 0.37, 0.83, 0.86, 0.55), IV: 3.99 (1.08, 0.39, 0.89, 0.98, 0.65).
Palp as in Figures 14, 15 View Figures 14–19 , 20 View Figures 20–22 ; prolateral loop (Pl) short, ca. 1.5 times longer than wide; radical arms thin finger-like, several times longer than wide, subequal in length.
Female. Habitus as in Figure 6 View Figures 1–7 . Total length 2.15. Carapace 0.85 long, 0.90 wide. AME 0.10, ALE 0.11, PME 0.08, PLE 0.06. Colouration as in male, dark markings more prominent. Measurements of legs: I: 3.02 (0.84, 0.38, 0.61, 0.67, 0.52), II: 3.23 (0.96, 0.33, 0.66, 0.66, 0.62), III: 3.18 (0.91, 0.33, 0.70, 0.74, 0.50), IV: 3.57 (1.06, 0.33, 0.77, 0.85, 0.56).
Epigyne as in Figures 29–34 View Figures 23–34 ; epigynal plate ca. 1.25 times wider than long; anterior half with roundly curved transversal wrinkles; insemination ducts visible through integument, long, parallel; length/width ratio of rectangular area formed between insemination ducts ca. 5; ‘scape’ in macerated epigyne ( Figures 30–34 View Figures 23–34 ) somewhat T-shaped; sac parts of receptacles large, rounded, and contiguous ( Figures 32, 33 View Figures 23–34 ).
Distribution. Known only from the listed localities in Khatlon Region, south-western Tajikistan ( Figures 35, 36 View Figures 35–36 ).
