The Brown Accentor (Prunella fulvescens) is a poorly known bird species distributed in Eurasia highmontane areas. In this paper, we described the whole mitochondrial genome of the Brown Accentor. The entire mitochondrial sequences were determined using long-range PCR and conserved primer walking approaches. The results demonstrated that the whole mitochondrial genome of P. fulvescens was 16,837 bp in length with 54.1% A þ T content; the genome harboured the same gene order as that of other passerine birds, including 13 protein-coding genes, 2 rRNA genes, 22 tRNA genes and 1 non-coding control region. The control region (D-loop) of P. fulvescens was located between tRNA-Gln and tRNA-Phe with 1247 bp length. These mitochondrial data are potentially important for the further studies on molecular evolution and conservation genetics in avian species.
