(Figs 1–2)
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). Paratypes, three females with same data as holotype (AIMB).
Diagnosis. This new species can be differentiated from other Oriental species by the presence of bilobate glossa (Fig. 1B) and smooth, and posteriorly strongly narrowing first metasomal tergite (Fig. 2B). 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), 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).
Description. Female, holotype
Body length 3.1 mm, fore wing 3.0 mm.
Head. Head 1.2, 2.0 × wider than long anteriorly and dorsally. Face punctate, setose without short sulcus antero-medially, 1.5 × wider than long (Fig. 1B). Clypeus punctate, setose with straight ventral margin (Fig. 1B). Eye setose (Fig. 1B). Malar space 1.1 × basal width of mandible. Glossa distinct, bilobate (Fig. 1B). Frons concave medially, sparsely setose (Fig. 1C). Vertex and occiput smooth, setose (Fig. 1C). 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. Flagellomere 15 1.4 × as long as wide.
Mesosoma. Mesosoma 1.3 × as long as high. Mesoscutum punctate, setose (Fig. 1E). Middle lobe of mesoscutum moderately elevated (Fig. 1E). Notauli absent (Fig. 1E). Scutellar lunules narrowly crenulate (Fig. 1E). Scutellum sparsely punctate, moderately setose (Fig. 1E). Sides of scutellum smooth and polished (Fig. 1E). Lateral pronotum crenulate medio-posteriorly (Fig. 1D). Mesopleuron mostly smooth punctate anteriorly, sparsely setose anteriorly, heavily setose posteriorly (Fig. 1D). Metapleuron smooth, glabrous, sparsely setose along margins (Fig. 1D). Propodeum medially punctate and bulged, with longitudinal rugae medio-posteriorly, rest smooth without areola (Fig. 1F).
Wings. Fore wing 2.5 × as long as wide. Pterostigma 2.5 × as long as wide. Areolet absent (Fig. 2C). Vein r originating slightly after middle of pterostigma, 1.2 × as long as width of pterostigma (Fig. 2C). Vein 1CUa 1.1 × as long as 1CUb. Vein m-cu 1.2 × as long as (RS+M)b. Margin of hind wing vannal lobe setose.
Legs. Metafemur 3.2 × as long as wide. Metatibia 4.2 × as long as its maximum width. Metabasitarsus 4.4 × as long as wide.
Metasoma. Metasoma as long as head and mesosoma combined (Fig. 1A). Mediotergite 1 narrowing posteriorly, smooth, 1.9 × as long as its maximum width (Fig. 2B). Mediotergite 2 transverse, broadly triangular, smooth, 0.2 × as long as its maximum width (Fig. 2B). Second metasomal suture indistinct (Fig. 2B). Mediotergite 3 smooth, 0.3 × as long as its maximum width (Fig. 2B). Ovipositor long, distinctly decurved apically, 0.4 × as long as fore wing, ovipositor sheath 1.3 × as long as metatibia (Fig. 2A).
Colour. Body black except scape dorsally and ventrally, pedicel, maxillary and labial palps, glossa, fore and mid legs except coxa, metatrochanter, metafemur basally and apically, metatibia basal half, metatibial spurs, metatarsomeres, metasoma laterally, mediotergite 1, mediotergite 2 except medio-posteriorly, mediotergites 3–7 posteriorly, ovipositor yellow, tegula, metatibia apical half, mediotergites 2 medio-posteriorly, ovipositor sheath brown.
Male. Unknown.
Host. Unknown.
Distribution. India (Arunachal Pradesh) (Fig. 7).
Etymology. The species is named after the mediotergite 1 strongly narrowing posteriorly.
