Etymology. This species is named for our lab mate, carabid specialist, and enthusiastic supporter of this study, Igor M. Sokolov.

Diagnosis. This species can be distinguished from the other species of the auripila speciesgroup by the following combination of characters: larger body, length 2.3 mm; antennomere 1 approximately 2 times longer than wide, with dull surface; gular region of male head depressed roundly and densely setose; frontal sulcus deep reaching vertexal fovea; shape of genitalia unique to species.

Description of Male. Length 2.3 mm. Body brown, antennae, legs, maxillary palpi, and elytra paler ( Fig. 37h ). Head: Round, widest across eyes ( Fig. 37h ). Gular region roundly depressed and densely setose. Antennomere 1 approximately 2 times longer than wide, with dull surface, 2–3 subquadrate, 4–5 longer than wide, 6–10 subquadrate. Frontal sulcus deep, reaching end of head from frontal rostrum. Anterior frontal fovea round and partially covered by frontal rostrum, posterior frontal fovea elongate. Eye small, approximately one-third length of temple. Thorax: Prosternum as long as wide, widest at midpoint. Elytra approximately triangular ( Fig. 37h ). Meso-and metathorax trapezoidal, as long as wide. Aedeagus: Median lobe weakly curved as S-shaped ( Fig. 38i ). Phallobase of median lobe symmetrical and rounded ( Fig. 38i ).
