Phylogenetic analysis determines the position of Triplophysa qiubeiensis in the clade of Triplophysa species, suggesting its evolutionary relationships.
In this study, the complete mitochondrial genome of Triplophysa qiubeiensis (Cypriniformes: Nemacheilidae) was determined using the Illumina Novaseq 6000 platform. The mitogenome is 16,584 bp in length, and exhibits a gene composition and arrangement typical of the teleost fishes, containing 13 protein-coding genes, 22 tRNA genes, two ribosomal RNA genes, and a control region. The overall nucleotide composition was 30.63% A, 27.18% T, 16.37% G, and 25.82% C. Phylogenetic analysis based on complete mitogenome sequences placed T. qiubeiensis within a clade of Triplophysa species primarily distributed in the Yunnan-Guizhou Plateau of southwestern China.
