( Fig. 7)

Material examined: Ararat Province: 1♂ 1 juv, Garni Gorge, Azat River , 40°06'32"N 44°43'57"E, 1240 m, 17.v.2021 . Yerevan: 2♂ 1♀, city, on walls, 12–16.v.2021 . Vayot Dzor Province: 2 juv., Gnishik River canyon, road to Noravank Monastery , 39°41'14"N 45°13'21"E, 1400 m, 10.v.2021 .

Comments: In the Caucasus, this species was previously known only from four localities in Azerbaijan, including one in Nakhchivan ( Otto 2020). The record from Armenia is northwesternmost in the entire range (from Armenia to Sichuan, China; WSC (2021)). We have provided figures of the male and female habitus that are lacking in the literature and in internet. Males have slightly variable abdominal pattern and may have distinct or indistinct leg annulations (cf. Figs 7A & 7B). The epigyne ( Fig. 7D) of this species differs drastically from all congeners occurring in the Middle East.
