Characterization of the complete mitochondrial genome of Haemadipsa tianmushana Song 1977 (Hirudiniformes, Haemadipsidae) and its phylogenetic analysis.

ABSTRACT: The complete mitochondrial genome of Haemadipsa tianmushana Song 1977 from China has been determined and reported for the first time in this study. It was 14,625 bp in length and consisted of 22 tRNA genes, 2 rRNA genes, 13 protein-coding genes (PCGs), and 3 control regions. The nucleotide base content of the complete mitogenome for this species was 35.1% A, 10.5% C, 11.6% G, and 42.8% T. The tRNA genes were ranged from 57 bp (Ser^TCT) to 66 bp (Gln^TTG) in length. The phylogenetic analyses indicated that Hirudinea is a mono-phyletic clade. And it includes Whitmania acranulata, Whitmania pigra, Whitmania laevis, Zeylanicobdella arugamensis, Ozobranchus jantseanus and Placobdella lamothei. In Hirudiniformes, H. tianmushana and three species of Haemopidae were obviously clustered into two independent branches. This result is consistent with a taxonomy that they all belong to the same suborder. This study adds to the genetic resources currently available for the species.
