Type locality: Nepal, Lamjung District , Manaslu Mountain, Bara Pokhari, 3800 -4100 m alt.

Diagnosis of males: Length 3.15 mm. Antennomere 9 with projection at apex, antennomeres 10 with distinct projection at base. Metaventral processes broad, and apically forked. Protrochanters with acute ventral spine, profemora with blunt ventral spine, protibiae with distinct projection at apex; mesotrochanters with long acute ventral spine, mesotibiae with two distinct projections at apex; metacoxae with large blunt ventral projection. Median lobe of aedeagus broad apically; parameres moderately elongate and apically broadened.

Description: Male ( Fig. 10B View Fig 10 ). Body reddish brown, BL 3.15 mm. Head longer than wide, HL 0.67 mm, HW 0.62 mm; each eye composed of about 45 facets; with well-developed ocular canthus. Antennomeres ( Fig. 12A View Fig 12 ) 9-11 forming distinct club, antennomeres 9 with projection at apex, antennomeres 10 with distinct projection at base. Pronotum ( Fig. 12B View Fig 12 ) as long as wide, PL 0.65 mm, PW 0.65 mm, angularly expanded at anterolateral margins, strongly constricted at apical third. Elytra wider than long, EL 0.96 mm, EW 1.34 mm. Metaventral processes ( Fig. 12C View Fig 12 ) broad, apically forked, anterior branch smaller than posterior branch. Protrochanters with acute ventral spine, profemora with large, blunt ventral spine ( Fig. 12D View Fig 12 ), protibiae ( Fig. 12E View Fig 12 ) with distinct projection at apex; mesotrochanters ( Fig. 12F View Fig 12 ) with long, sharp ventral spine; mesotibiae ( Fig. 12G View Fig 12 ) with two distinct projections at apex; metacoxae ( Fig. 12H View Fig 12 ) with large blunt ventral projection. Abdomen broad at base and narrowing apically, AL 0.87 mm, AW 1.31 mm. Sternite IX semi-membranous, shape as in Fig. 12I View Fig 12 . Length of aedeagus ( Figs 12 View Fig 12 J-L) 0.69 mm; median lobe broad and asymmetric (basal capsule collapsed in holotype); parameres narrowed at base and broadened apically; endophallus composed of one long and one short sclerites.

Female. Unknown.

Distribution: Nepal, Gandaki.

Comparative notes: The new species is a member of the P. bagmatius species-group, and can be readily recognized based on the unique forms of the male antennal clubs, the distinct large ventral projection of the metacoxae, and the broad apex of the median lobe of the aedeagus.

Etymology: The specific epithet refers to the large blunt projection of the metacoxa of the new species.
