Balanomorph species are hydrothermal vent endemic barnacles. In the genus , three species are known to date and they distribute at three different vent fields in Pacific and Indian Oceans, in the Southwest Pacific Ocean, in the East Pacific Ocean, and in the Indian Ocean. Therefore, species are considered to be a meaningful model taxon to elucidate the evolutionary history of vent organism in relation to geotectonic events. Here, we characterized the partial mitogenome of a newly described vent barnacle Chan et al., 2020 from the Solitaire vent field in the Indian Ocean. The length of mitogenome was 16,804 bp with 64.0% AT content. Its gene content and organization was identical to those of . There was one significant part in the mitogenome of , which was a long intergenic region over 2 kb found between tRNA and tRNA. The phylogenetic tree suggested the monophyly of and with high supporting values. In the future, additional mitogenome analysis of the last species, , could expand our understanding about the speciation and global distribution of species.
龟甲藤壶属物种是热液喷口特有的藤壶。在该属中，迄今为止已知有三个物种，它们分布在太平洋和印度洋的三个不同喷口区，一个在西南太平洋，一个在东太平洋，一个在印度洋。因此，该属物种被认为是一个有意义的模型分类单元，有助于阐明与地质构造事件相关的喷口生物的进化历史。在此，我们对一种新描述的来自印度洋索莱泰尔喷口区的喷口藤壶（Chan等人，2020年）的部分线粒体基因组进行了特征分析。线粒体基因组长度为16,804 bp，AT含量为64.0%。其基因内容和组织与[另一物种]相同。在[该物种]的线粒体基因组中有一个显著部分，即在tRNA和tRNA之间发现的一个超过2 kb的长基因间隔区。系统发育树表明[该属的几个物种]具有单系性且支持值很高。未来，对最后一个物种[具体物种名称未给出]的线粒体基因组进行额外分析，可能会扩展我们对该属物种的物种形成和全球分布的理解。
