ABSTRACT: A new species, Myxobolus zhaltsanovae sp. n. is described from the gills of gibel carp Carassius auratus gibelio during a survey of myxozoans from the watershed of Lake Baikal based on morphological and molecular characterizations. Plasmodia of M. zhaltsanovae sp. n. develop extravascularly and measure 500–1000 μm long; 25–100 μm wide. The myxospore is circular to oval and has polar capsules that are unequal and suspherical, measuring 13.23 ± 0.09 (11.3–14.8) µm in length, 10.19 ± 0.07 (9.1–11.4) µm in width, 6.49 ± 0.12 (5.4–7.2) µm in thickness. Measurements of polar capsules are: length 5.62 ± 0.06 (4.7–6.7), width 3.44 ± 0.04 (2.4–4.4) µm and length 3.42 ± 0.05 (2.5–4.1), width 1.9 4± 0.04 (1.3–3.3) µm. Phylogenetic analysis with the 18S rDNA gene shows Myxobolus zhaltsanovae n. sp. as a sister species of the subclade formed by M. musseliusae, M. tsangwuensis, and M. basilamellaris, that infect common carp Cyprinus carpio.
