Description. Body length 2.7–3.5 mm. Body (Fig. 1 B) relatively robust and elongate in dorsal aspect. Head black; antennae, pronotum and elytra brown to dark brown, elytra paler than pronotum; abdominal tergites dark brown to black, posterior margin of each tergite paler; legs yellowish brown. Head surface glossy, with fine punctation, distance between punctures 2–3 times longer than their diameter; head about as long as wide, widest at middle; eyes about 1.2 times longer than tempora; antennomeres 4–7 slightly elongate, 8–10 about as long as wide, 11 about as long as preceding two combined (Fig. 3 A); labrum broadly emarginate in anterior margin; a-sensillum long, pointed at apex; prementum with medial pseudopores absent and lateral pseudopores present. Pronotum slightly transverse, approximately 1.2 times as wide as long, widest at apical 2/5; midline pubescence directed anteriorly; punctation finer than on head, distance between punctures 1.5–3 times longer than their diameter; metanotal scutum with one long setae and about 3–4 short setae on each side of midline; mesoventral process elongate and distinctly pointed at apex, longer than metaventral process; length ratio of mesoventral process, isthmus and metaventral process 7:4:2 (Fig. 3 B). Elytron approximately 1.7 times as long as wide, postero-lateral margin very weakly sinuate; flabellum composed of about 16 setae. Abdominal tergites glossy, with fine punctation, distance between punctures 1–2 times longer than their diameter; male tergite VIII (Fig. 3 C) with 4 macrosetae on each side of midline, posterior margin subtruncate; male sternite VIII with 8 macrosetae on each side of midline, microsetae of postero-medial region distinctly denser than other regions, posterior margin truncate; posterior margin of female tergite VIII emarginate; posterior margin of female sternite VIII (Fig. 3 D) weakly emarginate, conspicuous marginal setae present. Aedeagus as in Figs. 3 E–G.
Material examined. KOREA: Chungnam prov.: 24 ex., Gongju-si, Banpo-myeon, Mt. Gyeryongsan, Donghaksa, 12 vi 1999, US Hwang; Gangwon prov.: 6 ex., Hoengseong-gun, Cheongil-myeon, Mt. Balgyosan, 5 vii 1998, HJ Lim, KL You.
Distribution. Korea and Russia (East Siberia) (Smetana 2004).
Remarks. This species is similar to P. palustris, but can be distinguished by the characters provided in the key and the shape and structure of aedeagus.
