Type material.

Holotype ♂ (ZMMU): Tajikstan, environs of Dushanbe, Hissar Mt. Range, 48th km of Varzob Hwy, S exposed slope with Juglans litter & under stones, 38°55'31"N, 68°48'18"E, 1530 m, 7.05.2015 (Y.M. Marusik, M. Saidov). Paratypes: 1♂1♀ (IZCAS), same data as holotype.


The species is named after Sergei Zonstein (University of Tel-Aviv, Israel) a partner of the junior author in the expedition to Tajikistan; noun (name) in genitive case.


The male can be distinguished from all other Pireneitega species except Pireneitega involuta ( Wang et al., 1990) by having a broad conductor and thick patellar apophysis. From Pireneitega involuta it is distinguished by the blunt tip of the patellar apophysis (vs a tapering tip in Pireneitega involuta ) (Fig. 1; Wang et al. 1990: figs 13-15). The female can be distinguished from all other Pireneitega species except Pireneitega fedotovi by having a nearly trapezoidal atrium, long copulatory ducts, and short receptacles. From Pireneitega fedotovi it can be distinguished by its short epigynal teeth, about 0.5 times as long as length of the atrium (vs long epigynal teeth in Pireneitega fedotovi , about as long as the length of the atrium) (Fig. 2; Charitonov 1946: fig. 4).


Male (holotype): Total length 8.90. Carapace 4.40 long, 3.50 wide. Abdomen 4.50 long, 2.80 wide. Eye sizes and interdistances: AME 0.15, ALE 0.20, PME 0.15, PLE 0.20; AME-AME 0.07, AME-ALE 0.06, PME-PME 0.15, PME-PLE 0.18. Leg measurements: I: 12.95 (3.50, 4.30, 3.15, 2.00); II: 12.25 (3.25, 4.00, 3.00, 2.00); III: 10.40 (3.15, 3.00, 3.25, 1.00); IV: 16.00 (4.50, 5.00, 4.25, 2.25). Carapace greenish, the radial grooves indistinct, with black lateral margins. Abdomen blackish, with yellow herringbone pattern.

Spination in male

Palp as in Fig. 1: patellar apophysis long, more than half length of tibia; tibia short, about 1/4 length of tarsus; VTA subequal to the tibial length, without pointed tip, extending beyond the tibia; RTA short, about 1/6 length of VTA; cymbial furrow long, more than half length of cymbium; conductor broad and with two spiraling loops; median apophysis broad and nearly triangular; embolus with broad base originating proximally on base of tegulum.

Female (paratype): Total length 10.0. Carapace 4.75 long, 3.65 wide. Abdomen 5.25 long, 3.45 wide. Eye sizes and interdistances: AME 0.20, ALE 0.25, PME 0.21, PLE 0.26; AME-AME 0.08, AME-ALE 0.05, PME-PME 0.17, PME-PLE 0.20. Leg measurements: I: 12.50 (3.75, 4.25, 2.75, 1.75); II: 11.75 (3.50, 4.00, 2.75, 1.50); III: 10.60 (3.00, 3.50, 2.60, 1.50); IV: 15.00 (4.25, 4.75, 4.00, 2.00). Carapace yellow. Abdomen black, with yellow spots and herringbone pattern.

Epigyne as in Fig. 2 A–B: epigynal teeth narrow and relatively short (shorter than width of atrium); septum short with weakly sclerotized tip, about 0.3 times as long as wide; atrium with well delimited posterior margin, about 1.3 times longer than wide, about 4 times longer than septum, subequal to width of septum; copulatory opening hidden by anterior margin of atrium; receptacles long, about 2 times longer than wide, separated by 2.5 times their diameters; copulatory ducts with 3 parts, the basal part running from receptacle posteriorly (Bd), median part running anteriorly (Md), and terminal part (Td) running posteriorly and leading to copulatory opening; median part as wide as terminal and 2 times longer than basal part; median part 1.5 times longer than receptacle; median parts touching each other; hoods indistinct.
