Abstract Tylototriton ziegleri is distributed in northern Vietnam and is a new member of the genus Tylototriton. The conservation status of this species has not yet been assessed by the IUCN, but several other species of Tylototriton have been listed as near threatened or vulnerable due to habitat destruction and illegal hunting. We determined the complete sequence and structural characteristics of the mitochondrial genome of T. ziegleri. The entire mitogenome is 16,266 bp in length, and contains 13 protein-coding genes, 22 tRNA genes, two rRNA genes, a control region, and a non-coding region. The length, gene arrangement, and composition are similar to mitogenomes of other species of Tylototriton. A phylogenetic tree based on the mitogenome sequences of several Asian species within Salamandridae confirmed the genus Tylototriton * Dingqi Rao [email protected] * Mingwang Zhang [email protected] 1

Introduction Tylototriton ziegleri is a new member of the family Salamandridae, genus Tylototriton (Nishikawa et al. 2013), that is reported to inhabit Ha Giang and Cao Bang in northern Vietnam (Phimmachak et al. 2015). The conservation status of this species has not yet been assessed by the IUCN, but several other species of Tylototriton are listed as near threatened or vulnerable (IUCN 2016) due to habitat destruction or degradation caused by human activity and illegal hunting. The 21 species of the genus Tylototriton have been divided into two groups; the T. verrucosus species group and the T. asperrimus species group (Fei et al. 2005; Weisrock et al. 2006), and T. ziegleri belongs to the T. asperrimus species group (Nishikawa et al. 2013). However, delineating the sp
