Abstract: Quang River in Nghe An has high biodiversity, especially a large-sized freshwater softshell turtle species naturally distributed there. To clarify the classification of Quang River softshell turtles, 07 softshell turtle samples were collected from fishermen and classified by mitochondrial DNA sequencing, COI gene region. The results showed that a total of 610 bases had 04 polymorphic sites and 4 haplotypes were detected. The haplotype diversity coefficient was 0,02 ± 0,1 and the nucleotide diversity coefficient was 0,01. Comparison with DNA sequences of softshell turtles in the gene bank data (NCBI) showed that the softshell turtles in Quang River, Nghe An are the spiny softshell turtle species with the English name wattle-necked softshell turtle and the scientific name Palea steindachneri, different from smooth softshell turtles and flower softshell turtles. The research results are an important scientific basis for orienting the conservation, exploitation, and development of the genetic resources of Quang River wattle-necked softshell turtle in Nghe An.
