Two new myxozoan species are described from the musculature of fish caught around the Falkland Islands. Kudoa ramsayi sp. n. was found in three of 23 specimens of the marine nototheniid fish Patagonotothen ramsayi (Regan). Its spores differ in size and shape from those of Kudoa alliaria Shulman et Kovaleva, previously reported from the same host. Myxobolus bartoni sp. n. was found in one of six specimens of the diadromous fish Galaxias maculatus (Jenyns). Although four species of the genus Myxobolus have been reported from fish of the genus Galaxias elsewhere, this is the first report of a Myxobolus from G. maculatus in the Falkland Islands. It differs from the other four species in spore morphometrics and internal structure. In addition, we propose the name Myxobolus olidus nom. nov. to replace M. galaxii Langdon, 1990, which is preoccupied by M. galaxii Szidat, 1953.
