Diagnosis. Adult ( Figs 5, 6 ). Wingspan 32–34 mm. Subleuconycta palshkovi can be distinguished from S. calonesiota ( Figs 1–4 ) by the average smaller size; more greyish and lighter ground colour of fore- and hindwing; the presence of a brownish patch in the basal area; the smaller expanded dark line and brownish spot between the diffuse orbicular spot and reniform stigmata; the less angulate hindwing. It differs from S. sugii ( Figs 7, 8 ) by its smaller size; the greyish ground colour of the forewing; the thicker dark line and brownish spot between the diffuse orbicular spot and reniform stigmata without black outline. Male genitalia ( Figs 13–16 ). Subleuconycta palshkovi can be distinguished from S. calonesiota ( Figs 9–12 ) by the slightly wider valvae at the basal second fourth; the somewhat narrowing proximal part of the valvae; the finely curved, apically pointed saccular processus; from S. sugii ( Figs 17–20 ) by the basally narrower subdeltoidal shaped juxta; the slightly curved, medially broadening uncus; the somewhat straighter and narrower valvae; the basally wider valvae; the more terminal position of saccular processus. Subleuconycta palshkovi differs from S. calonesiota by its somewhat broader aedeagus; the somewhat broader and shorter coecum; the slightly larger basal and distal diverticulum of vesica; from S. sugii by the longer coecum; the smaller basal and well developed distal diverticulum of vesica. Male 8th abdominal segments ( Fig. 22 ). See the details under S. calonesiota . Female genitalia ( Fig. 26 ). Subleuconycta palshkovi differs from S. calonesiota ( Figs 24, 25 ) by its more triangular corpus bursae and slightly elongated appendix bursae; from S. sugii ( Figs 27, 28 ) by its triangular corpus bursae with the presence of signum and the long tube-like part of the corpus bursae.

Distribution. Russian Far East, Northeast China, Korean Peninsula and Japan.
