ABSTRACT
During a survey of the parasite fauna of the euryhaline notothenioid fish Eleginops maclovinus (Cuvier) caught in brackish
water creeks in the Falkland Islands, small white cysts were observed in the mesenteries and on the surfaces of the visceral
organs and heart. On dissection these proved to be plasmodia of a species of the myxosporean genus Henneguya. This is the first
record of a member of this genus from a marine or euryhaline fish in the south-west Atlantic. A comparison of the spore of our
species with other species in the genus convinced us that our species is new. This paper describes it as Henneguya shackletoni
sp. nov. after the Shackleton Fund which funded the study.
