Figs 30-48 , 76

Lycosa alticeps (Kroneberg, 1875) . – Ovtsharenko & Fet, 1980: 443. – Mikhailov & Fet, 1994: 508 (misidentification of specimens from Badkhyz).

Holotype: ISEA; male; TURKMENISTAN, Mary Velayat, c. 73 km NW of Serhetabat (= Kushka), Badkhyz (= Badhyz ) Reserve (c. 35°52’N, 61°40’E), cordon Kyzyl-Dzhar , clay slope ; 10.-14.IV.1993; leg. A.A. Zyuzin.

Paratypes: ISEA; 3 females; collected together with the holotype . – ZMMU; 1 male, 1 female; same data . – MMUE; 1 male, 1 female; same data .

Etymology: The species epithet is latinized adjective derived from the name of the type locality, the Badkhyz (= Badhyz) Reserve in Turkmenistan.

Diagnosis: The male of K. badkhyzica sp. nov. is most similar to that of K. repetek sp. nov. ( Figs 94, 98, 102 ), but differs in having a smaller and narrower proximal extension of the MA (wide, spade-shaped in K. repetek sp. nov.; Figs 40, 46 cf. Fig. 98 ) and an undivided, finger-shaped median tooth (bifurcated in K. repetek sp. nov.; Figs 30-31 , 42 cf. Figs 97, 100 ). The female of this species is similar to that of K. medica ( Figs 85-86 ), but can be readily distinguished by a shorter epigynal atrium ( Fig. 44 ) and by the shape of the spermathecae: anteriorly markedly swollen in K. badkhyzica sp. nov. ( Fig. 43 ), worm-shaped, anteriorly not swollen in K. medica ( Fig. 86 ).

Colouration in alcohol ( Figs 37-38 ): Carapace brownish, with a wide median longitudinal yellowish white band of setae along entire length of carapace and with two wide lateral brown longitudinal bands of setae; carapace sides with wide marginal bands of white setae. Sternum light brown, densely covered with white setae. Maxillae and labium brownish, with yellow tips. Chelicerae brown, proximal half of frontal side densely covered with white setae. Abdomen: dorsum densely covered with white setae, with a long, wide, yellow-brown cardiac mark; sides and venter densely covered with white setae. Booklung covers yellow, covered with white setae. Spinnerets brown. All legs yellow, densely covered with white setae; Mt I and Tr I brown, also densely covered with white setae. Palp yellow, with the brownish cymbium, densely covered with white setae.

Palp structure ( Figs 30-31 , 39-42, 45-48 ): Acutely pointed synembolic lamellae diverging from each other; median tooth finger-shaped, in some specimens with a basal tooth; proximal extension narrow, spatula-like; inner plate large, with an extended retrolateral shoulder; conductor triangular, pointed at its tip.

Female (paratype, MMUE). Measurements: Carapace 8.70 long, 6.50 wide. Eye sizes and interdistances: AME 0.45, ALE 0.38, PME 0.88, PLE 0.95, AME-AME 0.25, AME-ALE 0.15, PME-PME 0.93, PME-PLE 1.20. Width of anterior eye row 1.93, of second row 2.68, of third row 3.30. Clypeus height 0.30; chelicera length 4.35. Abdomen 8.76 long, 6.40 wide. Length of leg segments: I 6.60 + 3.20 + 4.90 + 4.50 + 2.80 (22.00); II 6.50 + 3.20 + 4.30 + 4.30 + 2.70 (21.00); III 5.30 + 2.50 + 3.60 + 5.10 + 2.80 (19.30); IV 7.50 + 3.00 + 5.30 + 6.70 + 3.50 (26.00). Leg formula: IV, I, II, III.

Colouration in alcohol ( Figs 32-35 ): Carapace yellowbrown, densely covered with white setae and with two paramedian longitudinal bands of brown setae. Sternum brownish yellow, densely covered with white setae. Maxillae and labium brown, with yellow tips. Chelicerae dark brown, proximal half of frontal side densely covered with yellowish white setae. Abdomen: dorsum densely covered with white setae, with a large, wide, brownish cardiac mark and with a brownish pattern of transverse lines; sides and venter, including book-lung covers, densely covered with white setae. Spinnerets brownish. All legs and palps yellow, densely covered with white setae; tarsi of all legs darker (brownish). Palps with a claw at their tips.

Epigyne and vulva ( Figs 43-44 ): Epigynal atrium twice as long as wide, with lateral edges slightly biconvex; posterior transverse plate short, anchor-shaped; spermathecae tube-shaped, directed antero-mediad, inclined towards each other, distinctly swollen in anterior portion.

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

Habitat: This species occurs in sparse pistache woodland, with an undergrowth dominated by bulbous bluegrass ( Poa bulbosa ) and sedge ( Carex pachystylis ) ( Ovtsharenko & Fet, 1980: sub Lycosa alticeps ).
