( Figs 1–2 View FIGURE 1 View FIGURE 2 )
Material examined. Holotype, female INDIA: Arunachal Pradesh, Pasighat , 28°3’54.36” N, 95°10’17.4” E, 217 m. a.s.l., 5–20.x.2022, Malaise trap, coll. A.P. Ranjith ( AIMB) GoogleMaps . Paratypes, three females with same data as holotype ( AIMB) GoogleMaps .
Diagnosis. This new species can be differentiated from other Oriental species by the presence of bilobate glossa ( Fig. 1B View FIGURE 1 ) and smooth, and posteriorly strongly narrowing first metasomal tergite ( Fig. 2B View FIGURE 2 ). The new species is close to P. grandicula in having fore wing vein r distinctly longer than 2RS and not forming an angle ( Fig. 2C View FIGURE 2 ), but it differs from P. grandicula in having metatarsus paler than metatibia (darker than metatibia in P. grandicula ), gena finely punctate (rugose-punctate in P. grandicula ), flagellomere 15 1.4 × as long as wide (2.0 × in P. grandicula ), mediotergite 3 1.6 × as long as 2 (2.2 × in P. grandicula ) and propodeum punctate medially (smooth in P. grandicula ).

Glossa distinct, bilobate ( Fig. 1B View FIGURE 1 ). Frons concave medially, sparsely setose ( Fig. 1C View FIGURE 1 ). Vertex and occiput smooth, setose ( Fig. 1C View FIGURE 1 ). OOL: POD: POL = 1.4: 1.0: 1.7. Dorsal length of eye 1.5 × as long as gena. First flagellomere 1.2 × as long as second. First and second flagellomeres 2.4, 2.0 × as long as wide respectively.

Mesopleuron mostly smooth punctate anteriorly, sparsely setose anteriorly, heavily setose posteriorly ( Fig. 1D View FIGURE 1 ). Metapleuron smooth, glabrous, sparsely setose along margins ( Fig. 1D View FIGURE 1 ). Propodeum medially punctate and bulged, with longitudinal rugae medio-posteriorly, rest smooth without areola ( Fig. 1F View FIGURE 1 ).
Wings. Fore wing 2.5 × as long as wide. Pterostigma 2.5 × as long as wide. Areolet absent ( Fig. 2C View FIGURE 2 ). Vein r originating slightly after middle of pterostigma, 1.2 × as long as width of pterostigma ( Fig. 2C View FIGURE 2 ). Vein 1CUa 1.1 × as long as 1CUb. Vein m-cu 1.2 × as long as (RS+M)b.

Metasoma. Metasoma as long as head and mesosoma combined ( Fig. 1A View FIGURE 1 ). Mediotergite 1 narrowing posteriorly, smooth, 1.9 × as long as its maximum width ( Fig. 2B View FIGURE 2 ). Mediotergite 2 transverse, broadly triangular, smooth, 0.2 × as long as its maximum width ( Fig. 2B View FIGURE 2 ). Second metasomal suture indistinct ( Fig. 2B View FIGURE 2 ). Mediotergite 3 smooth, 0.3 × as long as its maximum width ( Fig. 2B View FIGURE 2 ). Ovipositor long, distinctly decurved apically, 0.4 × as long as fore wing, ovipositor sheath 1.3 × as long as metatibia ( Fig. 2A View FIGURE 2 ).

Male. Unknown.
Host. Unknown.
Distribution. India (Arunachal Pradesh) ( Fig. 7 View FIGURE 7 ).
