摘　　要：A complete mitogenome of T.lineatus from Lake Turkana in the Kenyan part was determined.It had a length of 16470 bp,including 37 genes as found in teleosts with the typical gene order in these fishes.Mitogenomic comparison and phylogenetic analysis supported not only the morphology-based recognition of the puf ferfish specimen from Lake Turkana as the Nile puf ferfish,but also the identification of the Chinese specimen recently recorded as T.lineatus and its African source.The mitochondrial genome here amplified for the sample of T.lineatus from Lake Turkana also provides conclusive molecular evidence for the monophyletic nature of Tetraodon s.s.,as it serves as a reference genome of this species used to clarify ambiguity in its identification in previous molecular studies.A complete mitogenome of T.lineatus from Lake Turkana in the Kenyan part was determined.It had a length of 16 470 bp,including 37 genes as found in teleosts with the typical gene order in these fishes.Mitogenomic comparison and phylogenetic analysis supported not only the morphology-based recognition of the puf ferfish specimen from Lake Turkana as the Nile puf ferfish,but also the identification of the Chinese specimen recently recorded as T.lineatus and its African source.The mitochondrial genome here amplified for the sample of T.lineatus from Lake Turkana also provides conclusive molecular evidence for the monophyletic nature of Tetraodon s.s.,as it serves as a reference genome of this species used to clarify ambiguity in its identification in previous molecular studies.
