title: The mitochondrial genome of the banded guitarfish, Zapteryx exasperata (Jordan and Gilbert, 1880), possesses a non-coding duplication remnant region.
abstract: The complete mitochondrial genome of the banded guitarfish is 17,310 bp long and includes 2 ribosomal RNA, 22 transfer RNA, and 13 protein-coding genes, a replication origin and a control region (GenBank accession number KM370325). Gene arrangement is similar to that found in other batoids. An extra non-coding region was found between the genes coding for transfer RNA proline and threonine possessing a set of tandem repeat motifs pointing to its origin as a duplication remnant. Start codon ATG and stop codon TAA/T were found in most protein-coding genes. The base composition of the genome is 32.3% A, 30.2% T, 24.3% C and 13.1% G.
