Abstract The mesoparasitic copepod Cardiodectes bellottii is described from specimens recovered from the myctophid fish, Benthosema glaciale in the Mediterranean Sea. Another parasitic copepod, found on the same host species, Cardiodectes meduseaus, exhibits identical external morphology, is conspecific with C. bellottii and is considered as a junior synonym.
