Karakumosa tashkumyr sp. nov.

Figs 142-155

Holotype: ISEA, 001.8406 ; male; KYRGYZSTAN, Dzhalalabad Area, N of Taşkomur (= Tash-Kumyr ) (c. 41°23’N, 72°14’E), clay hills; 14.-15.VI.1992; leg. A.A. Fedorov & A.A. Zyuzin.

Paratypes: ISEA; 7 males; collected together with the holotype . – ZMMU; 2 males; same data . – MMUE; 2 males; same data . – MHNG; 1 male; same data .

Etymology: The species epithet is a noun in apposition referring to the name of the type locality, Tash-Kumyr in Kyrgyzstan.

Diagnosis: In the presence of a low serrate flange at the foot of the median tooth of the MA, this species is most similar to K. shmatkoi sp. nov. ( Figs 107- 112 , 115-120, 123-125 , 128-135 ). The males of K. tashkumyr sp. nov. can be readily distinguished by the relative size of the inner plate of the MA, which in the ventral view is comparatively narrower and almost hidden beneath the outer plate in K. shmatkoi sp. nov. and wider and clearly visible in K. tashkumyr sp. nov. ( Fig. 148 cf. Fig. 118 and Fig. 119 ), and by the shape of the synembolus: both tips of the lamellae markedly bent downwards in K. tashkumyr sp. nov. vs. upper tip straight in K. shmatkoi sp. nov. ( Fig. 149 cf. Fig. 116 and Fig. 129 ). The female of K. tashkumyr sp. nov. is unknown.

Description: Male (paratype, ISEA). Measurements: Carapace 12.00 long, 8.60 wide. Eye sizes and interdistances: AME 0.55, ALE 0.40, PME 1.10, PLE 1.20, AME-AME 0.30, AME-ALE 0.20, PME-PME 1.00, PME-PLE 1.50. Width of anterior eye row 2.55, of second row 3.35, of third row 4.00. Clypeus height 0.43; chelicera length 5.50. Abdomen 10.50 long, 6.80 wide. Length of leg segments: I 11.50 + 5.10 + 11.00 + 12.40 + 5.20 (45.20); II 11.50 + 4.80 + 10.20 + 12.40 + 5.40 (44.30); III 11.00 + 4.40 + 8.80 + 12.50 + 5.50 (42.20); IV 13.00 + 4.70 + 10.10 + 15.40 + 6.00 (49.20). Leg formula: IV, I, II, III.

Colouration in alcohol ( Figs 142-143 ): Carapace brown, densely covered with yellowish white setae and with two wide brownish longitudinal bands. Sternum yelloworange-coloured, densely covered with white setae. Maxillae half brownish and half yellow-orange-coloured. Labium brownish yellow, with a yellow tip. Chelicerae dark brown, their frontal and lateral sides densely covered with white setae. Abdomen: dorsum densely covered with white setae, with an indistinct brownish cardiac mark; sides and venter yellow, 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; metatarsi and tarsi of all legs ventrally darker (brownish). Palps yellow-orange-coloured, densely covered with white setae.

Palp structure ( Figs 145-154 ): Acutely pointed synembolic lamellae bent downwards; median tooth developed as a large median claw with additional small teeth on its prolateral side and a prominent ventral flange looking like an additional tooth; proximal extension wide and hook-shaped; distance between proximal extension and median tooth wide, equal to two proximal extension widths; inner plate large, transverse-ovoid, its retrolateral shoulder bent ventrad; conductor triangular, obtuse at its tip.

Female. Unknown.

Distribution: Only known from the type locality, north of Taşkomur in Dzhalalabad Area of Kyrgyzstan ( Fig. 155 ).
