RESUMEN
The Fossorochromis rostratus is a species of cichlid endemic to Lake Malawi in East Africa. In this study, we first reported the complete mitochondrial genome of F. rostratus. The whole mitochondrial genome is 16 581 bp in length, which contains 13 protein-coding genes, 22 transfer RNA genes, and two ribosomal RNA genes. The GC content of this mitochondrial genome is 45.96% (27.47% A, 26.57%T, 30.12% C, and 15.84% G), similar to Astatotilapia calliptera (the GC content of 45.90%). We constructed a phylogenetic tree on the complete mitochondrial genomes of these two species and other 10 closely related species to show their phylogenic relationship. The complete mitochondrial genome of F. rostratus and its phylogenic relationship with other related species would facilitate our understanding of the evolution of Cichlidae mitochondrial genome.
