Colour. Body brownish including antenna, eye, pterostigma, and ovipositor sheath.

Distribution. India ( Himachal Pradesh).

Etymology. The species epithet is derived from the collection locality.

Comments. The new species differs from P. harishi Ranjith & van Achterberg, 2020 ( Ranjith et al. 2020) in the following set of characters: antenna with 20 antennomeres, length of first flagellomere subequal to second flagellomere; length of first, second and penultimate flagellomeres 7.0, 7.0 and 2.2 × as long as wide respectively ( vs 18 antennomeres; 1.1 ×; 3.0, 2.6 and 1.6 × as long as wide, respectively in P. harishi ); length of eye 2.4 × as long as temple in dorsal view ( vs 1.5 ×); intertentorial distance 4.3 × as long as tentorio-ocular distance ( vs 3.25 ×); length of hind femur, tibia, basitarsus 3.6, 9.7 and 6.7 × as long as wide, respectively ( vs 2.6, 10.25 and 6.5 ×); length of first tergite 4.6 × its apical width ( vs 1.5 ×); length of second tergite 0.9 × its apical width ( vs 0.5 ×); length of ovipositor sheath 0.8 × first tergite ( vs 1.4 ×).

The new species also differs from P. songyangensis ( He, 2000) mainly by having fewer antennal antennomeres (20 vs 24 in P. songyangensis ) and largely smooth propodeum ( vs medio-posteriorly propodeum longitudinally rugulose). The new species differs from P. pallidus Austin & Wharton, 1992 in having the pterostigma 3.0 × as long as wide ( vs 2.0 × as long as wide in P. pallidus ) and hypopygium 1.8 × as long as first tergite ( vs 2.4–2.5 × as long as first tergite).
