Turkmenistan: Balkan Province: 1♂ 1♀ (ZMMU), south-western Kopetdagh, Yoldere (= Eldere ) Valley , [38°31'N, 56°23'E], under garland thorn, 25.05.1982 (N.S. Ustinova) ; 1 juv. (ZMMU), Aydere Valley , [38°24'N, 56°45'E], 27.05.1980 (V.Y. Fet) . Iran: Razavi Khorasan Province: 1♂ (only palp) (ZMFUM), Torbat-e Jam, Ghader Abad , [35°16'N, 60°37'E], 05.2014 (B. Jannesar) .

Note.

Dunin and Fet (1985) stated that all type series (consisting of 16 males and 12 females) were deposited in ZISP. However, according to D.V. Logunov (personal communication), the material could not be located there. Three specimens were found in ZMMU, consisting of one male, one female without endogyne and a juvenile.
