Metasoma. (L: W=32.0:19.5); T1 with longitudinal foveae, laterally and posteriorly smooth; T2 anteromedially smooth, followed by basal foveae, from which several longitudinal striae extend 0.8 × length of tergite; posterior margin of T2 slightly convex; T1 with two lateral setae; T2 4.4 × the length of T1.

Male. Not known.

Etymology.

This species is named after the Cholas, a major dynasty, that ruled for well over a millennium in South India. The name is treated as a noun in apposition.
