Metasoma. (L: W=37.0:25.6); T1 longitudinally foveate, smooth laterally and posteriorly; T2 with basal foveae, followed by longitudinal striae extending 0.7 × length of tergite; remaining tergites smooth; posterior margin of T2 slightly convex; T1 with three lateral setae and one sublateral seta; T2 5.1 × length of T1.

Male. Not known.

Etymology.

This species is named ‘Pallava’, after an early South Indian dynasty that ruled between the 4th and 9th centuries CE. The name is treated as a noun in apposition.
