Figs 44–45, 61

Diagnosis

The species can be easily distinguished from any congeners by having the elongated, straight tibial apophysis of male palp, which is longer than the tibia (Fig. 44B), whereas shorter than tibia or curved in congeners (Metzner 2023).

Etymology

The specific name is the patronym in honor of Dr Dmitri V. Logunov, who contributed significantly to the taxonomy of the genus Stertinius; noun (name) in genitive case.
