Material examined. KYRGYZSTAN: Jalal-Abad Region: holotype ♂ ( ZMMU) Western Tian Shan Mountains, Chatkal Mt. Range, Sary-Chelek Reserve , near Arkit , 1500 m, Juglans regia forest, 05.05.1983 ( S. Zonstein) . Paratypes 1♀ 2juv. ( ZMMU) Kirghizsky Mt. Range, Malinovoye Canyon , 20 km S of Frunze [now Bishkek], 1500 m, 27.07.1983 ( S.V. Ovtchinnikov) . KAZAKHSTAN: Almaty Region: 1♀ ( ZMMU) Trans-Ili Alatau Mt. Range, Bol’shoye Almaatinskoye Lake , 43°05’N, 76°59’E, 3000 m, 3– 10.07.1995 (YM & O.A. Karacheva) GoogleMaps .

Diagnosis. The species is most similar to S. shtoppelae sp. n. and S. nekhaevae sp. n. but can be distinguished from these by the club-shaped dorsal lobe of the anterior “receptacle” (vs. cylindrical dorsal lobe with narrowed tip in both related species) (cf. Figs 8E View FIGURE 8 , G–H and 8B, D; 8C, F). It differs from S. shtoppelae sp. n. by the presence of speckles on the abdomen (cf. Figs 1E and 1C View FIGURE 1 ; 2B and 2C View FIGURE 2 ; 3B and 3D View FIGURE 3 ). Male of S. turkestanica can be distinguished from S. shtoppelae sp. n. by less pronounced paddle on the tip of embolus (cf. Figs 7C and 7D View FIGURE 7 ). Moreover, S. turkestanica can be separated from S. nekhaevae sp. n. by much less pronounced pillar-shaped glands on walls of the ventral lobe of the anterior “receptacle” (cf. Figs 8H and 8 View FIGURE 8 I–J). Female of S. turkestanica differs well from other East Palaearctic species by a globular (club-like) head of the dorsal lobe of “receptacle” ( Figs 8E View FIGURE 8 , G–H).

Description. Described by Dunin (1986). Here we present only habitus figures, description of copulatory organs and spination of leg I.

Male palp ( Figs 5 View FIGURE 5 C–D, 7C): femur equal in length to patella+tibia; cymbium slightly longer than femur; bulb 1.25 times longer than femur, oblong-conical, with distinctly S-shaped bent terminal part of embolus, tip membranous.

Endogyne ( Figs 8E View FIGURE 8 , G–H, 9J–L, 10 C, F, J–K, O): dorsal lobe of the anterior “receptacle” club-shaped, pillarshaped glands absent; stalk very long; ventral lobe trapezoidal.

In addition, in the original description described the spination incorrectly, specifically the ventral spines of the Ti I were recorded as unpaired. However, the spination of the Ti I of the holotype shows paired spines (p1-0-1-1, r1-1-0-1, v2-2-2-2).

Distribution. The species is known from the Chatkal, Baubashata, Fergana, Kungei-Alatoo and Kyrgyz Ranges in Kyrgyzstan and from the Trans-Ili Alatau Mt. Range in Kazakhstan ( Dunin 1986; new data). Segestria turkestanica was also recorded for “south-eastern regions” of Kazakhstan ( Logunov & Gromov 2012) based on unpublished record of A.V. Gromov ( Almaty, Kazakhstan), but the whereabouts of the reference material are not known.

Biology. This species lives in decidous and coniferous forests in the middle mountain belt ( Dunin 1986).

Comments. The present record of the species from the Trans-Ili Alatau Mt. Range represents the first record for Kazakhstan and is the northern-most record in the range of the species.
