Moon, Youn & Soh (2014) state that this species shares the generic characteristics of Parvocalanus (see Andronov 1970; Hiromi 1987; Boxshall and Halsey 2004) and that the differences are not relevant enough to put this Arabian taxon in Paracalanus. The authors propose: Parvocalanus arabiensis (Kesarkar & Anil, 2010), comb. n. supported by a Key to the genera of Paracalanidae (emended from Boxshall and Halsey, 2004).
