Pireneitega kovblyuki Zhang et Marusik, 2016: 101 , fig. 6 (♂).

Material examined: 2♂ 1♀ 3 juv. ( ZMMU): Tajikstan, Khatlon Area, Dangara Distr. , Sanglok Mt. Range near Shar-Shar Pass , 38°17'56"N, 69°13'36"E, 1700–2000 m, 29.04.2015 (S.L. Zonstein).

Diagnosis. Pireneitega kovblyuki is most similar to that of P. tyurai . Epigynes of both species have wide teeth, rebordered posterior part of fovea, short receptacles and very short median part of copulatory ducts. Both sexes of the two species well differ by size (carapace length 3.75 in P. kovblyuki vs. 2.15 in P. tyurai ) and abdominal pattern lacking in P. kovblyuki ( Figs 1–3 ), while P. tyurai has a well-developed series of chevrons in (fig. 4C in Zhang & Marusik 2016, Fig. 7 ). Females of related species can be separated by the shape of scape, which is triangular and well separated from foveal posterior part in P. tyurai (fig. 4A in Zhang & Marusik 2016), and longitudinal and fused with posterior part of fovea in P. kovbyuki ( Fig. 4 ). Pireneitega kovblyuki also has shorter epigynal teeth and receptacles, and longer fertilization ducts (cf. Figs 4–5 and fig. 4A–B in Zhang & Marusik 2016).

Description. Male. Described in Zhang & Marusik (2016).

Female. Total length 8.3. Carapace 3.75 long, 2.7 wide. Abdomen dorsally lacks distinct pattern ( Fig. 2 ), with 2 pairs of light spots and almost indistinct 3 light transversal stripes posteriorly; venter with lighter colouration and pair of wide dark bands around median light stripe ( Fig. 3 ). Leg length: I 9.8 (2.8, 3.4, 2.25, 1.35), II 8.6 (2.6, 2.9, 1.95, 1.15), III 7.93 (2.25, 2.6, 2.0, 1.08), IV 11.05 (3.05, 3.75, 3.0, 1.25).

Epigyne as in Figs 4–5 , septum (Se) fused with rebordered posterior part of fovea ( Rf) and appears like an inverted T; teeth short with rounded tip, about 2 times longer than wide; receptacles about 1.6 times longer than wide, separated by less than 2 times their width; fertilization ducts short and thin, spaced, middle part (Md) as long as receptacle width.

Note. Zhang & Marusik (2016) mentioned the lack of patellar apophysis (Pa) in the male of this species, although it is present ( Fig. 6 ), but strongly reduced in comparison to other species.
