Abstract Two morphologically novel Kudoa species are characterized from brain tissue of fish, Kudoa chaetodoni n. sp. from Chaetodon unimaculatus (Chaetodontidae) and Kudoa lethrini n. sp. from Gymnocranius audleyi and Lethrinus harak (Lethrinidae). Additionally we characterized a 5-spore valve (SV) Kudoa species from the brain of Sillago ciliata (Sillaginidae). Intriguingly, its 18S rDNA sequence was identical to that of the 7 SV Kudoa yasunagai extracted from the brain of a paralichthyid halibut in Japan. These 2 species may either prove to be con-specific, even though morphology and distribution differ, or demonstrate the limit of specific resolution in the small subunit rDNA gene region. Small subunit rDNA sequences from these new species were used in molecular phylogenetic analyses of kudoids to examine congruence of phylogeny with tissue tropism, geographical distribution, and host specificity. There was significant correlation between tissue tropism in the form of well-supported brain and heart-infecting clades. Host specificity and geographical distribution showed some correlations with genotype.
