RESUMEN
Discogobio brachyphysallidos Huang 1989 is a Cyprinidae fish species that is endemic to the upper Pearl River. In the present study, the complete mitochondrial genome of D. brachyphysallidos collected from the Nanpanjiang River was sequenced and annotated. The mitochondrial genome encompassed 13 protein-coding genes, two ribosomal RNA (rRNA) genes, 22 transfer RNA (tRNA) genes, and the control region (D-loop). The total length of the mitochondrial genome was determined to be 16,594 base pairs (bp), with a GC content of 41.7%. Phylogenetic analyses revealed that D. brachyphysallidos may be a sister to D. longibarbatus and D. macrophysallidos. These findings provide insight into the genetic information and phylogenetic relationships of D. brachyphysallidos.
