Synopsis of myxosporean species (Cnidaria: Myxozoa) parasitizing fishes from Vietnam

This paper provides an updated checklist of species-level identified myxosporeans from marine and freshwater fishes in Vietnam. The list includes 51 nominal species (38 marine and 13 freshwater) belonging to 9 genera: Myxobolus Butschli, 1882 (26 species); Kudoa Meglitsch, 1947 (6 species); Henneguya Thelohan, 1892 (6 species); Thelohanellus Kudo, 1933 (5 species); Unicapsula Davis, 1924 (2 species); Ceratomyxa Thelohan, 1892 (2 species), Zschokkella Auerbach, 1909 (2 species); Auerbachia Meglitsch, 1960 (1 species), and Meglitschia Kovaleva, 1988 (1 species). For each parasite species, information on myxospore morphology, line drawings, fish hosts, infection sites, and collection locality in Vietnam are reported. Where available, we also provide GenBank accession numbers for nucleotide sequence data. In addition, taxonomic status of several species was discussed and Myxobolus eszterbaueri nom. nov. is proposed as a junior homonym for Myxobolus hakyi Baska, Voronin, Eszterbauer, Muller, Marton & Molnar 2009, which is preoccupied.

Automated summary

This paper presents an updated checklist of species-level identified myxosporeans from both marine and freshwater fishes in Vietnam. The checklist includes a total of 51 nominal species, belonging to 9 different genera. For each parasite species, detailed information on morphology, host fishes, infection sites, and collection locality in Vietnam is provided. In addition, the taxonomic status of certain species is discussed and a new junior homonym is proposed.
