We present the complete mitochondrial genome of the Sharpnose/Granulated Guitarfish Glaucostegus granulatus, obtained with whole genome shotgun sequencing of genomic DNA. The 16,547 bp long circular genome consisted of 13 protein-coding genes, 22 tRNA genes, 2 rRNA genes, and a non-coding control region. A few protein-coding genes ended with incomplete stop codons. Phylogenetic analysis provided strong support for the specimen to be identified as G. granulatus and improved resolution of phylogeny within the genus Glaucostegus such as placing G. thouin in a sister group with G. typus. This is the first complete mitogenome within the genus Glaucostegus and will be beneficial to future molecular taxonomic studies and species identification, population studies and conservation efforts involving G. granulatus.
