The specific name is a patronym in honour of the collector of the type series and our friend and colleague Kirill Y. Eskov (Moscow), who made significant contributions to the study of Siberian spiders. Remark. The configuration of the conductor and the epigyne as well as the presence of three retromaginal teeth on the chelicerae set this species apart from the other species in the tesquorum group and its placement in this group is tentative. 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. Carapace dark brown with light brown median band, distinct in thoracic part, widening but more obscure in cephalic part behind PLEs, as well as light brown lateral bands, each broken into three short longitudinal spots.
