In addition, 4 ♂ and 1 ♀ from Japan ( ZIN) were examined .

COMPARATIVE DIAGNOSIS. Body length 8.0–9.7 mm. Dorsum black, with a golden shine ( Figs 1, 2 ). Basal antennomere reddish brown, other antennomeres dark brown to black, much darker than basal antennomere. Body pubescence yellow; setae on elytral disc very dense, noticeably deflected backward and usually relatively shorter than those in P. fumatus . Pronotum relatively narrower ( PW / PL 1.27–1.33, mean 1.30). Fourth pro-, meso- and metatarsomeres in both sexes more shallowly emarginated apically, with apical angles not forming long lobes (as in Figs 2–6 ). Male genitalia ( Figs 13–17, 23–25, 29, 30 ): median lobe of aedeagus sharply bent at middle ( Fig. 14 ) and with a very large narrow sclerotized process in internal sac ( Figs 29, 30 ); ventrobasal lobe of everted endophallus large, bent caudally ( Fig. 24 ), with large spines; the right laterobasal lobe larger than the left lobe, covered with spines ( Fig. 25 ); gonopore shifted to the left, its sclerite asymmetrical – the left part with a long appendage ( Figs 23–25 ).

DISTRIBUTION. The species has been described from Japan (Honshu: “Marshes, Ogura Lake; Uyeno and Honjo, in Tokio ”) ( Bates, 1883). It is also known from the northeastern part of China (Heilongjiang, Jilin, Liaoning, Beijing, and Hebei) and the Russian Far East (Häckel & Kirschenhofer, 2014; Makarov & Sundukov, 2022). Based on the examined material, in the Russian Far East it is distributed throughout the Primorsky krai, reaching the very south of the Khabarovsky krai (Bikin District).

ECOLOGY. In Russia, the species occurs in meadows, banks of rivers and lakes, and edges of nemoral forests (Lafer, 1983).
