Diagnosis of males: Length 3.02-3.29 mm. Antennomeres 9 with projection at apex, antennomeres 10 with projection at base. Metaventral processes long, apically expanded, with additional pair of small triangular projections. Protrochanters with small ventral spine, profemora with large, blunt ventral spine, protibiae with small, blunt projection at apex; mesotrochanters with acute ventral spine, mesotibiae with small spine at apex.

Pronotum (Fig. 5B) longer than wide, PL 0.59-0.68 mm, PW 0.61-0.62 mm, angularly expanded at anterolateral margins, strongly constricted at apical third. Elytra wider than long, EL 0.76-0.82 mm, EW 1.06-1.25 mm. Metaventral processes (Fig. 5C) long, apically broadened, with pair of small triangular projection in addition to long processes. Protrochanters with small ventral spine, profemora with large, blunt ventral spine (Fig. 5D), protibiae (Fig. 5E) with blunt projection at apex; mesotrochanters (Fig. 5F) with acute ventral spine; mesotibiae (Fig. 5G) with small spine at apex; metatrochanters and metafemora (Fig. 5H) simple. Abdomen broad at base and narrowing apically, AL 1.02-1.11 mm, AW 1.09-1.40 mm. Sternite IX semimembranous, shape as in Fig. 5I. Length of aedeagus (Figs 5 J-L) 0.59 mm; median lobe strongly asymmetric, bifid at apex; parameres short and apically broadened; endophallus composed of two sclerites.

Female. Each eye composed of about 30 facets; antennae simple. Measurements: BL 3.02-3.03 mm, HL 0.65- 0.68 mm, HW 0.59-0.61 mm, PL 0.62-0.65 mm, PW 0.61-0.62 mm, EL 0.71-0.73 mm, EW 1.12-1.16 mm, AL 0.99-1.02 mm, AW 1.26-1.31 mm.

Distribution: Nepal, Koshi.

Comparative notes: The new species belongs to the P. bagmatius species-group, and can be readily separated from all congeners of the group based on the angulate pronotal lateral margins, the broad male protibiae, and the unique forms of the male antennal clubs and the aedeagus.

Etymology: The specific epithet refers to the bi-lobed apex of the aedeagal median lobe of the new species.
