Note.

This species was described on the basis of the holotype female with the male unknown.

Diagnosis.

This species is similar to Clubiona bakurovi (Mikhailov, 1990: f. 61-65), but can be distinguished by the hilt-like ventral branch of RTA, the tip of the embolus short and anti-clockwise, the EP wedge-shaped lacking a large tooth; the absence of epigynal grooves; the copulatory openings situated on the posterior edge of epigyne, and the septum thin.
