Certain confusions are possible with Paracalanus parvus and Paracalanus quasimodo, hence the locality records to confirm in the Atlantic Ocean.
For Bradford (1978, p.137) there is some doubt that New Zealand specimens and those considered by Bowman (1971) are conspecific. Nevertheless this name is retained pendig closer examination of P. indicus on a world-wide scale.
