description: Segestria turkestanica Dunin, 1986
Figs 1 E–F, 2B, 3D, 4D, 5C–D, 7C, 8E, G–H, 9J–L, 10 C, F, J–K, O, 12B.
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).
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, 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; 2B and 2C; 3B and 3D). 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). 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 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, 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 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, 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.
