Figs 6–7 , 9

Diagnosis

Differs from other species of the genus by its darker coloration, legs with no fringe, longer chelicerae, and much wider and heavier embolus ( Fig. 6 E–F). Copulatory openings oriented antero-laterally, accessory glands situated posteriorly on spermathecae ( Fig. 7G ).

Etymology

This species is named for Dr. Dmitri Logunov, a distinctive Russian arachnologist (now at the University of Manchester), a friend of ours.
