Etymology.
The species is named after our colleague Sergei L. Esyunin from Perm University (Russia), noun.

Males of the new species differ from all congeners by the large embolic spine directed prolaterally. Females of Gnaphosa esyunini sp. n. substantially differ from other species by the very wide fovea and the shape and angle of the lateral pockets.
