Abstract
The diving beetles Dytiscus sharpi is one of the most critically endangered species in Japan, caused by excessive capture and destruction of their habitats. Here, the complete mitochondrial genome sequence (mitogenome) of D. sharpi is described. The entire mitogenome sequence was 19,476 bp long, containing 13 protein-coding genes, 2 ribosomal RNA genes, 22 transfer RNA genes, and 1 control region. The average A + T content of mitogenome was 81.3%. This is the first description of a complete mitochondrial genome of Dytiscus, and the second of Dytiscinae. The primary genetic data obtained in this study is expected to contribute to conservation genetic studies using various genetic analysis methods, including environmental DNA.
