Ratio of height of clypeus: intertentorial distance: tentorio-ocular distance = 1.0: 1.3: 1.0. Length of malar space 1.4 × basal width of mandible. Length of eye 2.3 × as long as temple in dorsal view. Frons longitudinally striate medially, faintly rugose laterally ( Fig. 1C View FIGURE 1 ). Vertex and occiput faintly rugose, setose ( Fig. 1C View FIGURE 1 ). Ratio of POL: OD: OOL= 1.3: 1.0: 3.3.

Mesosoma. Mesosoma 1.5 × as long as high. Mesosoma dorso-ventrally flattened. Pronotum crenulate laterally ( Fig. 1D View FIGURE 1 ). Propleural lobe present ( Fig. 1D View FIGURE 1 ). Mesoscutum faintly rugose, setose ( Fig. 1E View FIGURE 1 ). Notauli impressed only anteriorly ( Fig. 1E View FIGURE 1 ). Scutellar sulcus more or less straight, crenulated divided by 6 crenulae ( Fig. 1E View FIGURE 1 ). Scutellum smooth, sparsely setose ( Fig. 1E View FIGURE 1 ). Lateral sides of scutellum distinctly crenulate ( Fig. 1E View FIGURE 1 ). Metanotum smooth medially, crenulated postero-laterally, more or less smooth antero-laterally ( Figs 1E, F View FIGURE 1 ). Mesopleuron smooth ( Fig. 1D View FIGURE 1 ). Precoxal sulcus long, smooth sometimes weakly crenulate ( Fig. 1D View FIGURE 1 ). Sternaulus impressed, faintly crenulated ( Fig. 1D View FIGURE 1 ). Metapleuron smooth medially with distinct medial pit ( Figs1D View FIGURE 1 , 2A View FIGURE 2 ).Propodeum with distinctly marginated smooth areas ( Fig. 1F View FIGURE 1 ). Propodeum slightly curved in lateral view, not differentiated into anterior and posterior part ( Fig. 1D View FIGURE 1 ). Transverse carina absent medially ( Fig. 1F View FIGURE 1 ). Posterior side of propodeum with distinct transverse carina ( Fig. 1F View FIGURE 1 ). Propodeal areola hexagonal, smooth, 1.4 × as long as maximum width ( Fig. 1F View FIGURE 1 ).

Wings. Fore wing ( Fig. 2C View FIGURE 2 ): Fore wing infuscated below pterostigma and near vein cu-a ( Fig. 2C View FIGURE 2 ). Pterostigma 2.6 × as long as wide. Vein 1-R1 as long as pterostigma. Vein m-cu 0.3 × as long as vein 1-M. Vein M+CU distinctly curved. Vein cu-a slightly postfurcal. Vein r absent. Vein r-m absent. Hind wing ( Fig. 2D View FIGURE 2 ): ratio of veins M+CU: 1-M: 1r-m = 3.1: 1.3: 1.0.

Legs. Hind femur, tibia and basitarsus 3.0, 3.7 and 2.5 × as long as maximum width, respectively.

Metasoma. Metasoma 0.5 × as long as head and mesosoma combined. First tergite rugose anterior half, longitudinally striate posterior half, 1.4 × as wide as long, setose ( Fig. 2B View FIGURE 2 ). Second tergite indistinctly longitudinally striate 2.3 × as wide as long, setose ( Fig. 2B View FIGURE 2 ). Metasomal tergites 3–6 smooth, setose ( Fig. 2B View FIGURE 2 ). First and second metasomal suture present, crenulate ( Fig. 2B View FIGURE 2 ). Ovipositor sheath exerted, setose apically ( Figs 2A, B View FIGURE 2 ).

Color. Body yellow except eye grey, ocellar triangle, pterostigma, tarsal claw brown.

Male. Unknown.

Biology. Unknown.

Distribution. India (Kerala).

Etymology. The species is named after the yellow colored body.

Comparative diagnosis. The new species, P. flavus is similar to the new species P. striatus in having antenna with 22 antennomeres. Apart from the differences mentioned in the key, P. flavus differs from the latter by having the following morphological structures; frons with more than one longitudinal carinae medially (only one midlongitudinal carina in P. striatus sp. nov.), third metasomal tergite smooth (sculptured basally in P. striatus sp. nov.), and third and fourth antennomeres 2.7, 1.5 × as long as wide respectively (2.3, 2.2 × as long as wide in P. striatus sp. nov.).
