Complete mitochondrial genome sequence of has a circular genome of 16,552 bp, which is comprised 13 protein-coding genes, 2 rRNA genes, and 22 tRNA genes. The nucleotide composition of the light strand is 43.16% of A, 26.78% of T, 20.18% of C, and 9.88% of G. All genes are encoded on the heavy strand except seven tRNA genes (, , , , , , and ) on the light strand. All the protein-coding genes start with ATC initiation codon except ND4 starts with GTG, and two types of inferred termination codons are TAA and TAG. There are 26 intergenic spacers and 4 gene overlaps. It is indicated that has closer genetic relationship with (88.64% nucleotide sequence identity between them) than the other snail species.
的完整线粒体基因组序列具有一个16552 bp的环状基因组，它由13个蛋白质编码基因、2个rRNA基因和22个tRNA基因组成。轻链的核苷酸组成为：A占43.16%，T占26.78%，C占20.18%，G占9.88%。除了轻链上的7个tRNA基因（、、、、、和）外，所有基因都在重链上编码。除了ND4以GTG起始外，所有蛋白质编码基因都以ATC起始密码子开始，两种推断的终止密码子是TAA和TAG。有26个基因间隔区和4个基因重叠区。结果表明，与（它们之间的核苷酸序列同一性为88.64%）的亲缘关系比其他蜗牛物种更近。
