The complete mitochondrial genome of Tetrastemma olgarum (Nemertea: Hoplonemertea)

The complete mitochondrial genome (mitogenome) of Tetrastemma olgarum is sequenced. It is 14,580 bp in length and contains 37 genes typical for metazoan mitogenomes. The gene order is identical to that of the previously published Hoplonemertea mitogenomes. All genes are encoded on the heavy strand except for trnT and trnP. The coding strand is AT-rich, accounting for 69.2% of overall nucleotide composition.
