Holotype ♂ and allotype ♀ from RUSSIA, Yakutia, Lena River, Zhigansk Village (66°46'02''N 123°22'25''E), July 1989 (K.Y. Eskov) in ZMMU. - Paratypes. RUSSIA.

Eskov, IZAS, ISEA, ZMMU), 8♀; 40 km up from Kempendyai Village (62°02'N 118°37'E), July 1988 (K.Y. Eskov ISEA, NHRS, ZMMU), 10♀. Etymology. The specific name is a patronym in honour of the collector of the type series and our friend and colleague Kirill Y.

Diagnosis. Males can be distinguished from other congeners by an abruptly cut tip of embolus, long conductor with sclerotized distal part protruding obliquely forwards, and small terminal apophysis (Fig. 16). Females can be recognised by the wide transversal posterior part of septum (Fig. 19). Description. Male (holotype). Total length 4.9. Carapace 2.45 long, 1.85 wide. Prosoma.
