Huang W.C., Thu P.T., Liao T.Y. 2020. A new record of the long moray, Gymnothorax longinquus (Actinopterygii: Anguilliformes: Muraenidae), from southern Vietnam, supporting the uncertain record in the Gulf of Thailand. Acta Ichthyol. Piscat. 50 (2): 201–207.
Five specimens of Gymnothorax longinquus (Whitley, 1948) were collected from a fish market and a fish landing site in Tac Cau and Ha Tien, southern Vietnam. These specimens represent the first record of G. longinquus in Vietnam, and further support a previously uncertain record in Thailand. The specimens collected are described and illustrated. Gymnothorax longinquus may prefer muddy shallow water from northern Australia to the Gulf of Thailand.
