The maritae identified as I Derogenes varicus i were found in 10 fish species from the White Sea and 3 fish species from the Barents Sea (Table 1). 24 Køie M. (1990. b) A new cystophorous cercaria in Lunatia pallida (Broderip & Sowerby) (Naticidae): possibly the cercaria of Hemiurus levinseni Odhner, 1905 (Digenea, Hemiuridae). Experimental data on DV2 cercariae are ambiguous: Køie (1990b) succeeded in infecting 3 copepod species by cystophorous cercariae from I E. pallida i , but those copepods did not survive for more than several weeks.
