Cavia aperea which is a Brazilian guinea pig is found in the South America. Recently the genome sequencing of C. aperea was done, but no more information of its mitochondrial had been reported. Herein, we assembled the complete mitochondrial genome sequence of C. aperea. It is a 16 835 bp long sequence with most mitogenome's characteristic structure; 13 protein-coding genes, 2 rRNA genes, 22 tRNA genes, 1 D-loop region, 1 repeat region and 3 STS regions. The GC-content of our fresh sequence is 39%. It can verify the accuracy and utility of newly determined mitogenome sequences by the phylogenetic analysis, based on whole mitogenome alignment with C. porcellus, which is the closest relative to C. aperea. We expect that using the full mitogenome we can address the taxonomic issues and study the related the evolution events.
