Karakumosa gromovi sp. nov.

Figs 49-76

Holotype: ISEA; male; UZBEKISTAN, Surxondaryo Region , Baisun [= Boysun] Distr., c. 44 km SW of Denau [= Denov], SE foothills of Dzhetymkalyas Mt. Range (38°01’10.6”N, 67°28’06.3”E), c. 640 m. a.s.l.; 13.-14.V.1994; leg. A.V. Gromov.

Paratypes: ISEA; 1 female; collected together with the holotype . – ZMMU; 1 male, 1 female; same data . – MMUE; 1 male, 1 female; same data . – ISEA; 1 female; from the type locality; 14.V.1994; leg. A.V. Gromov & A.A. Zyuzin.

Etymology: This species is dedicated to our friend and colleague, Mr Alexander V. Gromov (Bingen-am-Rhein, Germany), who collected the type specimens.

Diagnosis: In the hook-shaped proximal extension of the MA, the male of K. gromovi sp. nov. is most similar to males of K. shmatkoi sp. nov. ( Figs 115-120 ) and K. tashkumyr sp. nov. ( Figs 145-154 ), but can be readily distinguished by the absence of a low serrate flange at the foot of the median tooth (present in K. tashkumyr sp. nov.; Figs 74-75 cf. Figs 107-112 and Figs 152-154 ). In the straight, subparallel lateral edges of the epigynal atrium, the female of K. gromovi sp. nov. is most similar to that of K. medica , from which it can be distinguished by the triangular posterior transverse plate of the median septum and by the wider and shorter spermathecae (anchor-shaped posterior transverse plate and wormshaped spermathecae in K. medica ; Figs 61-62 , 72-73 cf. Figs 85-86 ).

Length of leg segments: I 8.90 + 3.90 + 6.80 + 6.00 + 3.10 (28.70); II 8.90 + 3.80 + 6.10 + 6.00 + 3.00 (27.80); III 6.70 + 2.90 + 5.20 + 6.30 + 2.90 (24.00); IV 8.50 + 3.50 + 6.90 + 8.00 + 3.80 (30.70). Leg formula: IV, I, II, III.

Colouration in alcohol ( Figs 51-54 , 70-71 ): Carapace brown, densely covered with white setae and with a well-marked pattern of two wide yellowish brownish longitudinal paramedian bands. Sternum yellow, densely covered with white setae. Maxillae and labium brown, with yellow tips. Chelicerae dark brown, proximal half of frontal side and lateral sides densely covered with yellowish white setae. Abdomen: dorsum densely covered with white setae, with a brownish cardiac mark and a pattern consisting of brownish transverse stripes, patches and speckles; sides and venter yellow, densely covered with white setae. Book-lung covers yellow, densely covered with white setae. Spinnerets greyish yellow. All legs yellow brownish, densely covered with white setae. Palp yellow brownish, densely covered with white setae, with a tarsal claw.

Epigyne and vulva ( Figs 61-62 , 72-73 ): Epigynal atrium twice as long as wide, with straight subparallel lateral edges; posterior transverse plate markedly triangular, its posterior margin angular; spermathecae pear-shaped, their tips directed medio-anteriad, inclined towards each other.

Distribution: Only known from the type locality in southern Uzbekistan ( Fig. 76 ) where this species occurs together with another large burrowing wolf spider: Zyuzicosa baisunica Logunov, 2010 ; see Logunov (2010) for further information on the latter species.
