The entire mitogenome of Tylototriton kweichowensis is 16 727 bp in length. It consists of 13 protein-coding genes (PCGS), 2 ribosomal RNA genes (rRNA), 22 transfer RNA genes (tRNA), and 1 control region (CR). Except for ND6 subunit and 8 tRNA genes are distributed on the L-strand, all the other PCGs and tRNA genes are located on the H-strand. "ATG" and "GTG" are the start codons of the PCGs, "TAA", "AGA", "TA-" and "T--" are the stop codons. Most of the tRNA genes can be folded into typical clover-leaf secondary structure. The genome of T. kweichowensis has two repeat sequences in the cob-noncoding region. Mitogenomic phylogenetic analysis (NJ tree) robustly resolved the genus-level relationship among the three genera Tylototriton, Echinotriton, and Pleurodeles, and which is congruent with the previous molecular phylogeny results.
贵州疣螈的完整线粒体基因组长度为16727 bp。它由13个蛋白质编码基因（PCG）、2个核糖体RNA基因（rRNA）、22个转运RNA基因（tRNA）和1个控制区（CR）组成。除ND6亚基和8个tRNA基因分布在L链上外，所有其他PCG和tRNA基因都位于H链上。“ATG”和“GTG”是PCG的起始密码子，“TAA”、“AGA”、“TA-”和“T--”是终止密码子。大多数tRNA基因可以折叠成典型的三叶草二级结构。贵州疣螈的基因组在cob非编码区有两个重复序列。线粒体基因组系统发育分析（NJ树）有力地解析了疣螈属、棘螈属和肋突螈属这三个属之间的属级关系，这与先前的分子系统发育结果一致。
