Type locality: Nepal, Sindhupalchok District, Melamchi, Thare Pati, 3300 m alt.

Diagnosis of males: Length 3.10-3.13 mm. Antennomeres 9 with large disc-shaped process at apex, antennomeres 10 with small projection at base. Metaventral processes broad, forked at apex. Profemora with triangular ventral spine, protibiae with distinct spine at apex; mesotrochanters with slender ventral spine, mesotibiae with small projection at apex; metacoxae with short ventral projection. Median lobe of aedeagus broad and asymmetric at apex; parameres short.

Description: Male ( Fig. 16A View Fig 16 ). Body reddish brown, BL 3.10-3.13 mm. Head longer than wide, HL 0.61- 0.62 mm, HW 0.53-0.56 mm; each eye composed of about 43 facets. Antennomeres ( Fig. 17A View Fig 17 ) 9-11 forming distinct club, antennomeres 9 with large disc-shaped process at apex, antennomeres 10 with small projection at base. Pronotum ( Fig. 17B View Fig 17 ) slightly longer than wide, PL 0.61-0.62 mm, PW 0.58-0.59 mm, angularly expanded at anterolateral margins, strongly constricted at apical third. Elytra wider than long, EL 0.88- 0.94 mm, EW 1.12-1.19 mm. Metaventral processes ( Fig. 17C View Fig 17 ) broad, apically forked, anterior branch shorter than posterior branch. Profemora ( Fig. 17D View Fig 17 ) with triangular ventral spine, protibiae ( Fig. 17E View Fig 17 ) with distinct spine at apex; mesotrochanters ( Fig. 17F View Fig 17 ) with acute ventral spine; mesotibiae ( Fig. 17G View Fig 17 ) with small tubercle at apex; metacoxa ( Fig. 17H View Fig 17 ) with short ventral projection. Abdomen broad at base and narrowing apically, AL 0.96-0.99 mm, AW 1.12-1.14 mm. Sternite IX semi-membranous, shape as in Fig. 17I View Fig 17 . Length of aedeagus ( Figs 17 View Fig 17 J-L) 0.65 mm; median lobe broad and asymmetric; parameres short, almost symmetric; endophallus composed of one long and one short sclerites.

Female. Each eye composed of about 35 facets; antennae simple. Measurements: BL 3.06-3.12 mm, HL 0.65- 0.67 mm, HW 0.56-0.59 mm, PL 0.61-0.62 mm, PW 0.58-0.61 mm, EL 0.79-0.81 mm, EW 1.20-1.25 mm, AL 0.97-1.06 mm, AW 1.29-1.32 mm.

Distribution: Nepal: Bagmati.

Comparative notes: The new species belongs to the P. bagmatius species-group, and can be readily separated from all other members of the group based on the relatively long elytra and forked metaventral processes of the male, as well as the unique form of the aedeagus.

Etymology: The specific epithet refers to the large discshaped process of the male antennomeres 9 of the new species.
