Ceratomyxa chauvanminhi n. sp. was detected in 16% (8\/50) of cultured barramundi Lates calcarifer (Bloch) specimens, and Ceratomyxa sekoi n. sp. was found in 20% (5\/25) of wild largehead hairtail Trichiurus lepturus Linnaeus specimens. The spores of C. chauvanminhi n. sp. are very shallowly ovoid, slightly crescent shaped, and 11.5 \u00b1 0.5 (10.7\u201312.4) \u00b5m thick, 5.8 \u00b1 0.2 (5.4\u20136.1) \u00b5m long, and 5.5 \u00b1 0.2 (5.2\u20135.7) \u00b5m wide. Their posterior angles are slightly concave at 158.7\u00b0 \u00b1 4.2\u00b0 (151.3\u00b0\u2013164.8\u00b0), and they possess 2 equal spherical polar capsules 2.5 \u00b1 0.2 (2.1\u20132.9) \u00b5m in diameter. The spores of C. sekoi n. sp. are 5.6 \u00b1 0.2 (5.0\u20136.1) \u00b5m long, 75.5 \u00b1 4.8 (68.9\u201390.0) \u00b5m thick, and 5.5 \u00b1 0.1 (5.4\u20135.6) \u00b5m wide, with 2 equal, slightly anterior spherical polar capsules 2.1 \u00b1 0.2 (1.7\u20132.4) \u00b5m in diameter. Although C. sekoi n. sp. spores resemble those of species of Myxodavisia Zhao, Zhou, Kent, and Whipps, 2008, characterized by long tapering valves, genetic analyses distinctly place this new species within the Ceratomyxa Th\u00e9lohan, 1892 lineage. This study contributes to the understanding myxosporean diversity in Vietnamese waters and highlights the difficulty associated with distinguishing between the genera Ceratomyxa and Myxodavisia.<\/jats:p>","DOI":"10.1645\/24-2","type":"journal-article","created":{"date-parts":[[2024,8,26]],"date-time":"2024-08-26T22:54:21Z","timestamp":1724712861000},"page":"393-401","source":"Crossref","is-referenced-by-count":5,"title":["Two New Ceratomyxa Species (Myxosporea: Ceratomyxidae) Infecting the Gall Bladder of Marine Fishes from the South-Central Coast of Vietnam"],"prefix":"10.1645","volume":"110","author":[{"given":"Nguyen Ngoc","family":"Chinh","sequence":"first","affiliation":[{"name":"Institute of Ecology and Biological Resources, Vietnam Academy of Science and Technology, 18 Hoang Quoc Viet, Cau Giay, Hanoi 10072, Vietnam."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Vo Thi","family":"Ha","sequence":"additional","affiliation":[{"name":"Coastal Branch of Joint Vietnam\u2013Russia Tropical Science and Technology Research Centre, 30 Nguyen Thien Thuat, Nha Trang, Khanh Hoa 57000, Vietnam."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tran Duc","family":"Dien","sequence":"additional","affiliation":[{"name":"Coastal Branch of Joint Vietnam\u2013Russia Tropical Science and Technology Research Centre, 30 Nguyen Thien Thuat, Nha Trang, Khanh Hoa 57000, Vietnam."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mai","family":"Dang","sequence":"additional","affiliation":[{"name":"Institute of Veterinary Research and Development of Central Vietnam, Km 4, 2\/4 street, Vinh Hoa, Nha Trang, Khanh Hoa 57000, Vietnam."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Pham Ngoc","family":"Doanh","sequence":"additional","affiliation":[{"name":"Institute of Ecology and Biological Resources, Vietnam Academy of Science and Technology, 18 Hoang Quoc Viet, Cau Giay, Hanoi 10072, Vietnam."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6139-0426","authenticated-orcid":false,"given":"Christopher M.","family":"Whipps","sequence":"additional","affiliation":[{"name":"College of Environmental Science and Forestry, Environmental Biology, State University of New York, 1 Forestry Drive, Syracuse, New York 13210."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sho","family":"Shirakashi","sequence":"additional","affiliation":[{"name":"Aquaculture Research Institute, Kindai University, 3153 Shirahama, Nishimuro, Wakayama, 649-2211, Japan."}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1220","reference":[{"key":"32","doi-asserted-by":"crossref","unstructured":"C.
