Etymology

This species is named ‘ tanugatra ’, which means ‘slim’ in Sanskrit referring to the narrow metasoma. The name is treated as a noun in apposition.

Diagnosis

This species is closer to C. robustus , but differs from it in the following character states. In C. tanugatra , the horn on T1 is anteriorly smooth; the metasoma is narrow and at least 3.2× as long as wide; T1–T5 striate, the space between the costae is broad and smooth; T6 medially smooth and laterally reticulate. In C. robustus the horn on T1 is striate; the

metasoma is wide and at most 2× as long as wide; T1–T4 is costate, the space between the costae is narrow; T5–T6 is finely reticulate.
