Etymology
This species is named after Dame Agatha Christie, the internationally recognised queen of detective fiction. The name is treated as a noun in the genitive case.
Diagnosis
This species resembles C. valluvari sp. nov. and C. sarvatra, but differs from them in having OOL longer than POL, OOL> 4.3× MOD and a triangular interantennal process with a wide base; while in the latter two species POL is longer than OOL, OOL <3.3× MOD and the interantennal process is rectangular and elongate.
