(Figs 3–4)
Material examined. Holotype, female INDIA: Arunachal Pradesh, Yemsing, 28°7’39.72” N, 94°57’50.796” E, 1258 m.a.s.l., 28.iv.2022, sweep net, coll. A.P. Ranjith (AIMB). Paratype, 1 female with same data as holotype (AIMB).
Diagnosis. This species can be differentiated from other Oriental species by the following combination of characters: all coxae black (Fig. 3A), mediotergite 1 parallel sided, yellow basal half (Figs 4B, C), and mediotergite 2 faintly longitudinally striate medially (Fig. 4B). The new species looks morphologically closer to P. flava sp. nov., but it differs in the following characters; metasoma dorsally mostly dark brown, with only anterior half of mediotergite 1 and lateral areas on mediotergite 3 and 3 yellow (metasoma entirely yellow in P. flavus), and mediotergite 1 smooth on anterior half and mediotergite 2 mostly smooth (Mediotergite 1 and 2 entirely and strongly sculptured with longitudinal striae in P. flavus).
Description. Female, holotype

Head. Head 1.1, 2.0 × wider than long anteriorly and dorsally. Face punctate, setose with a short shallow sulcus antero-medially, 1.7 × wider than long (Fig. 3B). Clypeus punctate, setose with straight ventral margin (Fig. 3B). Eye setose (Fig. 3B). Malar space 1.0 × basal width of mandible. Glossa absent (Fig. 3B). Frons concave medially, sparsely setose (Fig. 3C). Vertex and occiput smooth, setose (Fig. 3C). OOL: POD: POL = 1.3: 1.0: 1.3. Dorsal length of eye 1.4 × as long as gena. First flagellomere as long as second. First and second flagellomeres 2.4, 2.6 × as long as wide respectively. Flagellomere 15 2.0 × as long as wide.
Mesosoma. Mesosoma 1.3 × as long as high. Mesoscutum punctate, setose (Fig. 3E). Middle lobe of mesoscutum distinctly elevated (Fig. 3E). Notauli absent (Fig. 3E). Scutellar lunules widely crenulated medially, narrowly crenulated laterally (Fig. 3E). Scutellum sparsely punctate, sparsely setose (Fig. 3E). Sides of scutellum smooth and polished (Fig. 3E). Lateral pronotum crenulate medio-posteriorly (Fig. 3D). Mesopleuron mostly smooth, punctate anteriorly, sparsely setose, heavily setose posteriorly (Fig. 3D). Metapleuron mostly smooth, rugose posteriorly, sparsely setose along posterior margin (Fig. 3D). Propodeum smooth medially, rugose-punctate medially, transversely striate postero-laterally without areola, with longitudinal rugae medio-posteriorly (Fig. 3F).
Wings. Fore wing 2.6 × as long as wide. Pterostigma 2.4 × as long as wide. Areolet absent (Fig. 4D). Vein r originating slightly after middle of pterostigma, 1.0 × as long as width of pterostigma (Fig. 4D). Vein 1CUa as long as 1CUb. Vein m-cu as long as (RS+M)b. Margin of hind wing vannal lobe setose.
Legs. Metafemur 2.8 × as long as wide. Metatibia 4.0 × as long as wide. Metabasitarsus 3.8 × as long as wide.
Metasoma. Metasoma 0.9 × as long as head and mesosoma combined. Mediotergite 1 parallel sided, smooth on anterior 2/3, coarsely longitudinally rugose-striate posterior 1/3, 1.5 × as long as its maximum width, sparsely setose posteriorly (Figs 4B, C). Mediotergite 2 transverse, rectangular, faintly longitudinally rugose-striate medio-posteriorly, 0.3 × as long as its maximum width (Fig. 4B). Second metasomal suture indistinct (Fig. 4B). Mediotergite 3 smooth, 0.3 × as long as its maximum width, sparsely setose (Fig. 4B). Ovipositor long distinctly decurved apically, 0.3 × as long as fore wing, ovipositor sheath 1.1 × as long as metatibia (Fig. 4A).
Colour. Body black except scape, pedicel, maxillary and labial palps, fore and mid legs except coxa and claw, metatrochanter, metafemur, anterior half of metatibia, metatibial spurs, metatarsomere, metasoma laterally, mediotergite 1 anterior 1/3, mediotergites 2–4 laterally yellow, flagellomeres, tegula, pterostigma, posterior half of hind tibia, ovipositor sheath brown.
Male. Unknown.
Host. Unknown.
Distribution. India (Arunachal Pradesh) (Fig. 7).
Etymology. The species is named after the incomplete sculpture of mediotergite 1.
