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 ).

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.).
