Head (Figs 15,16), in frontal view, 1.02× as broad as high with polygonal reticulate sculpture, eye height 5.5 × as long as malar space, malar space 0.20× oral fossa. mandible with two long teeth and two small blunt teeth dorsally ( Figure 17 ). Antennal toruli situated slightly above the lower eye margins. Antenna ( Figure 18 ) with scape 5.6× as long as broad, 2.83× as long as pedicel, pedicel 1.71× as long as broad, shorter than F1, flagellum with 3 anelli, funicle–3 segmented, F1 longer than all funicle segments individually, F2 subequal to F3, all funicle with mps, clava 2 – segmented, 2.75× as long as broad (including spicula), clava shorter than preceding two funicle segments combined, claval segment with mps.

Mesosoma ( Figure 21 ): Mesosoma 1.37× as long as broad, pronotum narrow, mesoscutum distinctly shorter than scutellum with 2 pair of setae, notauli complete, scutellum distinctly longer than broad with 1 pair of setae posteriorly, mesoscutum and scutellum with a longitudinal median groove ( Figure 21 ), and with polygonal reticulate sculpture ( Figure 22 ), metanotum with dorsellum sub-triangular and sides of the metanotum medially with irregularly curved vertical carinulae ( Figure 23 ), propodeum ( Figure 23 ) with large irregular carinulae anteriorly, and with a median carina, lateral plicae complete enclosing spiracles. Fore wing ( Figure 19 ) 2.48× as long as broad, marginal vein + parastigma 1.28× as long as submarginal vein, 5.14 × as long as stigmal vein, post marginal vein 0.42× stigmal vein. Hind wing ( Figure 20 ) 5.29 × as long as broad.

Metasoma ( Figure 24 ): Petiole 3.4× as broad as long, gaster distinctly longer than mesosoma, 1.36× as long as mesosoma, ovipositor almost as long as gaster, slightly exerted beyond apex of gaster and 1.90× as long as hind tibia.

Relative measurements (Holotype): Head height: width 35:36, eye height, 22, malar space, 4. Oral fossa, 19.5. Antennal segments length: width – scape, 17: 3, pedicel, 6: 3.5, F1, 6.5: 4, F2, 6: 3, F3, 5: 3, C1, 5: 4, C2, 4: 3, spicula, 1.5, mesosoma length: width 44: 32. Fore wing length: width 102: 41, submarginal vein length, 28, parastigmal vein length, 3, marginal vein length, 33, stigmal vein length, 7, postmarginal vein length, 3. Hind wing length: width, 90: 17, hind tibia length, 32. Petiole length: width, 3: 10, gaster length, 60, ovipositor length, 61.

Male: Unknown.

Material examined: Holotype: Female (on slide under four cover slips, slide No. ENT.482), INDIA: Karnataka: Halavarthy , 11. xii. 2020, Coll. A. Rameshkumar ( ZDAMU, registration No. HYM.CH.866).

Host: Unknown.

Distribution: India: Karnataka.

Etymology: The species name is derived from the locality ‘Halavarthy’, Koppal, Karnataka from where the holotype is collected.

Comments: The new species P. halavarthyensis sp. nov. apparently looks similar to P. haziqi . sp. nov. but differs in following characters: head, in frontal view, 1.02× as broad as high, eye height 5.5× as long as malar space, mandible with two long teeth, and two small blunt teeth dorsally, sides of metanotum medially with a row of irregularly curved vertical carinulae, propodeum with a median carina, ovipositor 1.90× as long as hind tibia. In P. haziqi : head in frontal view, 1.31× as broad as high, eye height 4.4× as long as malar space, mandible with two long teeth, and several small teeth dorsally, sides of metanotum smooth, propodeum without a median carina, ovipositor 1.97× as long as hind tibia.
