We compare the complete mitochondrial genomes of , , , and , five species of Hawaiian tree snails across three genera. Mitogenomes ranged in length from 15,187 to 16,793 base pairs, with a base composition of A (36.4-37.4%); T (42.2-42.7%); C (8.8-9.2%); and G (11.3-11.8%). Similar with other pulmonates, these mitogenomes contain 13 protein-coding genes, two ribosomal RNA genes, and 22 transfer RNA genes, with the order conserved among genera. Our study suggests polyphyly in the current arrangement of the subfamily Achatinellinae, part of a spectacular radiation in the Hawaiian Islands.
我们比较了三个属的五种夏威夷树蜗牛—— 、 、 、 和 的完整线粒体基因组。线粒体基因组长度在15,187至16,793个碱基对之间，碱基组成为：A（36.4 - 37.4%）；T（42.2 - 42.7%）；C（8.8 - 9.2%）；G（11.3 - 11.8%）。与其他肺螺亚纲动物相似，这些线粒体基因组包含13个蛋白质编码基因、两个核糖体RNA基因和22个转运RNA基因，各属之间顺序保守。我们的研究表明，当前玛瑙螺亚科的分类中存在多系现象，该亚科是夏威夷群岛一次壮观辐射演化的一部分。
