ACADEMIA JOURNAL OF BIOLOGY 2020, 42(2): 1–27 DOI: 10.15625/2615-9023/v42n2.14819 AN UPDATED LIST OF Monogenoidea FROM MARINE FISHES OF VIETNAM Nguyen Manh Hung*, Nguyen Van Ha, Ha Duy Ngo Institute of Ecology and Biological Resources, VAST, Vietnam Received 11 February 2020, accepted 16 April 2020 ABSTRACT In this paper, we updated the list of monogenean species from marine fishes of Vietnam. Taxonomic position of monogenean species were arranged according to the current classification system. A total of 220 monogenean species from 152 marine fish species were listed. Distribution, hosts and references of each species were given. In addition, amendations of taxonomic status of taxa were also updated.
