In this study, the complete mitochondrial genome of the flavescent peacock cichlid Aulonocara stuartgranti was determined. The mitochondrial genome is 16 669 bp in length, and encodes 1 D-loop region, 2 ribosomal RNA genes, 13 protein-coding genes, and 22 transfer RNA genes. Average GC content of this genome is 45.8%. ATP8 and ATP6 genes overlap by nine nucleotides, ND5 and ND6 genes by four nucleotides, and ND4L and ND4 genes share six nucleotides. All coding genes use ATG as start codon with except COX1 initiating with GTG. The phylogenetic tree involving 22 available closely related species further validated the newly determined sequences and phylogeny of A. stuartgranti.
