Erection of Ceratonova n. gen. (Myxosporea: Ceratomyxidae) to Encompass Freshwater Species C. gasterostea n. sp. from Threespine Stickleback (Gasterosteus aculeatus) and C. shasta n. comb. from Salmonid Fishes

Myxospores are arcuate, 22.4 +/-\ud 2.6 μm thick, 5.2 +/- 0.4 μm long, posterior angle 45 +/- 24°, with 2 sub-spherical polar\ud capsules, diameter 2.3 +/- 0.2 μm, which lie adjacent to the suture. Its ribosomal small subunit\ud sequence was most similar to an intestinal parasite of salmonid fishes, Ceratomyxa shasta (97%,\ud 1,671/1,692 nt), and distinct from all other Ceratomyxa species (
