After Mulyadi (2002, p.46) this species resembles C. aurivilli and C. americana.
The locality record given by C.B. Wilson (1950) in the Atlanic Ocean is considered very doubtful.
Uysal & al. (2002) report the presence of this species for the first time in the Eastern Mediterranean Sea (possible Lessepsian migration).
