In this study, the complete mitochondrial genome sequence of Amphilophus citrinellus was firstly sequenced and determined. The total genome is 16,522 bp in length with an A + T content of 54.19%, and contained 13 protein-coding genes, 22 tRNA genes, 2 ribosomal RNA genes and two main non-coding regions. The gene composition and order is similar to that of most other vertebrates, as is base composition and codon usage. These data will provide useful molecular information for phylogenetic relationships within the family Cichlidae species.
Keywords: Amphilophus citrinellus; Cichlidae; mitochondrial genome.
