摘要：
A new Myxobolus species, Myxobolus nekrasovi n. sp., was found in the gill arch of the gibel carp Carassius auratus gibelio during investigation of fish myxosporean fauna of ponds of Lake Baikal basin. The parasites were studied on the basis of spore morphology, as well as with histological and molecular methods. Mature spores of M. nekrasovi n. sp. are ellipsoidal in frontal view and lemon-shaped in lateral view, measuring 13.84 +/- 0.4 (12.2-15) mu m in length, 9.73 +/- 0.2 (8.5-10.7) mu m in width, 6,75 +/- 0.1 (6.0-7.6) mu m in thickness. Polar capsules are unequal and pyriform, measuring: length 6.31 +/- 0.1 (5.4-7.4), width 3.49 +/- 0.04 (3.12-4) mu m and length 2.88 +/- 0.1 (2.1-3.5), width 1.4 +/- 0.03 (1-1.6) mu m. Phylogenetic analysis with the SSU rDNA gene shows Myxobolus nekrasovae n. sp. as a sister species of the subclade formed by Thellohanellus sinensis, Myxobolus acutus, M. zhaltsanovae that infect gibel carp Carassius auratus gibelio.
