Characterization of the complete mitochondrial genome of the Sunda stink-badger (<i>Mydaus javanensis</i>) from the island of Borneo

The complete circular mitogenome was 16,391 base pairs in length. It comprises the typical 13 protein-coding genes, 22 tRNAs, two ribosomal RNA genes, one control region (CR) and an L-strand replication origin (O_L). The G+C content was 38.1% with a clear bias towards A and T nucleotides. Of the 13 PGCs, only ND6 was positioned in the reverse direction, along with five other tRNAs. Five PCGs had incomplete stop codons and rely on post-transcriptional polyadenylation (TAA) for termination. Based on the codon count, Leucine was the most common amino acid (589), followed by Threonine (332) and Isoleucine (325). The ML and BI phylogenetic trees, based on concatenated PCGs and the <i>cyt b</i> gene, respectively, correctly clustered the species with other members of the Mephitidae family but were unique enough to set it apart from <i>Conepatus</i>, <i>Mephitis</i> and <i>Spilogale</i>. The results confirm <i>Mydaus</i> as a member of the mephitids and the mitogenome will be useful for evolutionary analysis and conservation of the species.
