Abstract In the current study, Myxobolus episquamalis Egusa, Maeno & Sorimachi, 1990 (Myxozoa: Bivalvulida) is reported from the Lebranche mullet Mugil liza Valenciennes, 1836 in the estuarine region of the Maricá Lagoon, State of the Rio de Janeiro, southeastern Brazil. To date, this myxozoan species was reported in mullets from Asia, Africa, Europe, and Oceania. The characteristics of M. episquamalis previously reported are similar to the findings of the present study. DNA sequences of the nuclear small subunit ribosomal DNA (SSU rDNA) had 99.7–100% similarity with the sequences of M. episquamalis from North Africa and Asia. Therefore, strong morphological and molecular similarities ensure the identification of M. episquamalis in the current study. Finally, this finding records a new host and locality, revealing the worldwide distribution of this myxozoan species. Keywords Morphology . Sequencing . Myxozoa . Myxobolus episquamalis .

Introduction The Lebranche mullet Mugil liza Valenciennes, 1836 (syn. M. platanus Günther, 1880) is a catadromous pelagic fish from tropical and subtropical waters, mainly from estuarine coastal regions. It is distributed from the USA to Argentina,

occurring in saltwater, freshwater, and brackish water (Froese and Pauly 2019). Myxozoans are common parasites of marine and freshwater fish, rarely of amphibians and reptiles, and exceptionally of birds and mammals, representing an important pathogenic group with a worldwide distribution (Lom and Dyková 2006). Among myxozoans, the genus Myxobolus Bütschli, 1882 has the largest known diversity. In a revision of Eiras et al. (2014), a total of 905 Myxobolus spp. were checked and listed. Approximately 90 species of myxozoans have bee
