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.
