Etymology. This species is named for the collector of the holotype and staphylinid specialist, Alexey Y. Solodovnikov.

Diagnosis. This species can be distinguished from the other species of the socia species-group by the following combination of characters: body larger, length 2.4–2.6 mm; male antennomeres 8–10 enlarged with tubercles; eye prominent, one-third length of temple; male hind wings well-developed, female hind wings reduced to small pads; shape of genitalia unique to species.

Description. Length 2.4–2.6 mm. Body brown, antennae, elytra, legs, and maxillary palpi paler ( Fig. 47b ). Head: Male head round, widest across eyes ( Fig. 47b ). Ventral surface of head weakly convex. Antennomere 1 approximately 1.5 times longer than wide, 2–3 subquadrate, 4–5 longer than wide, 6–7 subquadrate, 8–10 transverse, male 8–10 enlarged with tubercles. Frontal sulcus deep, reaching posterior end of eye. Anterior frontal fovea oval, partially covered by frontal rostrum, posterior frontal fovea oval. Eye prominent, approximately one-third length of temple. Thorax: Prosternum as long as wide, widest at midpoint. Male elytra rectangular ( Fig. 47b ), female elytra subquadrate. Male hind wings well-developed, female hind wings reduced to small pads. Meso- and metathorax trapezoidal, longer than wide. Abdomen: Tergite IV with pair of transverse patches of microtrichia reaching middle. Aedeagus: Median lobe divided vertically, minor lobe broader and wave-shaped apically ( Fig. 47g ). Phallobase of median lobe symmetrical and rounded ( Fig. 47g ). Parameres symmetrical with setae apcially ( Fig. 47g ).

Distribution. Nelson ( Fig. 48 : triangles).

Habitat. Specimens of this species were collected using flight intercept or pitfall traps.
