Karakumosa repetek sp. nov.

Figs 76 , 89-102

Holotype: ISEA, 001.4309 ; male; TURKMENISTAN, Repetek (c. 38°35’N, 63°11’E), on light near a house; 7.VIII.1972; leg. G.T. Kuznetsov.

Paratypes: ISEA, 001.4310 ; 2 males; from the type locality; 31.VIII.1972; leg. G.T. Kuznetsov . – ISEA, 001.4213; 1 female; from the type locality; 21.VII.1985; leg. V.Ya. Fet .

Etymology: The species epithet is a noun in apposition referring to the name of the type locality, the Repetek Reserve in Turkmenistan.

Diagnosis: The male of K. repetek sp. nov. is most similar to that of K. badkhyzica sp. nov. ( Figs 40-42, 46-48 ), but differs in having a longer and wider, spade-like proximal extension of the MA ( Fig. 98 ) and a bifurcated median tooth (spatula-like proximal extension and finger-like median tooth in K. badkhyzica sp. nov.; Fig. 42 cf. Fig. 100 ). In the slightly sigmoid lateral edges of the epigynal atrium, the female of K. repetek sp. nov. is most similar to that of K. zyuzini sp. nov., from which it differs in the shape of the posterior transverse plate (dumbbell-shaped vs. with straight posterior margin; Fig. 96 cf. Fig. 179 ) and in the curved vs. straight spermathecae ( Fig. 95 cf. Fig. 182 ).

Eye sizes and interdistances: AME 0.50, ALE 0.38, PME 1.10, PLE 0.90, AME-AME 0.13, AME-ALE 0.10, PME-PME 0.85, PME-PLE 1.05. Width of anterior eye row 1.90, of second row 2.70, of third row 3.35. Clypeus height 0.33; chelicera length 4.00. Abdomen 9.20 long, 5.30 wide. Length of leg segments: I 9.80 + 4.20 + 9.10 (distal segments missing); II 9.70 + 3.80 + 9.00 + 11.70 + 5.00 (39.20); III 9.70 (distal segments missing); IV 11.40 + 4.20 (distal segments missing).

Colouration in alcohol ( Figs 89-90 ): Specimen damaged and shabby. Carapace yellow brownish, densely covered with white setae. Sternum yellow, densely covered with white setae. Maxillae and labium yellow, with white tips. Chelicerae yellowish brownish, their frontal and lateral sides densely covered with white setae. Abdomen: dorsum densely covered with white setae, with a poorly marked cardiac mark; sides and venter densely covered with white setae. Book-lung covers yellow, densely covered with white setae. Spinnerets yellow brownish. All legs yellow brownish, densely covered with white setae. Palp yellow, densely covered with white setae.

Palp structure ( Figs 93-94, 97-102 ; mirrored image of right palp): Acutely pointed synembolic lamellae convergent to each other or bent proximad; median tooth bifurcated at its tip; proximal extension wide and long, spade-like; inner plate transverse and relatively narrow, with an extended, obtuse retrolateral-proximal shoulder; conductor triangular, pointed at its tip.

Female (paratype). Measurements: Carapace 9.20 long, 7.20 wide. Eye sizes and interdistances: AME 0.53, ALE 0.35, PME 1.03, PLE 1.05, AME-AME 0.28, AME-ALE 0.10, PME-PME 1.15, PME-PLE 1.15. Width of anterior eye row 2.10, of second row 2.80, of third row 3.35. Clypeus height 0.40; chelicera length 5.25. Abdomen 11.00 long, 7.30 wide. Length of leg segments: I-II absent; III 7.20 + 3.50 + 4.80 + 6.50 + 4.00 (26.00); IV absent.

Colouration in alcohol ( Figs 91-92 ): Damaged specimen with only one legs remaining. Carapace brownish yellow, densely covered with white setae; its dorsal side with a brownish colour pattern consisting of two wide longitudinal paramedian bands. Sternum yellow, densely covered with white setae. Maxillae and labium yellow-brown, with yellow tips. Chelicerae brown, their frontal and lateral sides densely covered with white setae. Abdomen: dorsum densely covered with white setae, with a yellowish brown cardiac mark and a brownish colour pattern consisting of transverse stripes; sides and venter densely covered with white setae. Booklung covers yellow, densely covered with white setae. Spinnerets yellow brownish. All legs brownish yellow, densely covered with white setae. Palps lost.

Epigyne and vulva ( Figs 95-96 ): Epigynal atrium twice as long as wide, narrower at its proximal end and with slightly sigmoid lateral edges; posterior transverse plate dumbbell-shaped; spermathecae curved like a “C”, bent mediad and tips directed anteriad.

Distribution: Only known from the type locality, the Repetek Reserve in Turkmenistan ( Fig. 76 ).
