The dusky tripletooth goby, , is a good model organism for the small in size and reaching maturity within a single year. Previous studies mainly focused on the annual reproductive cycle, social behavior and life history, but little information is available of the mitochondrial genome and phylogenetic evolution of this gobioid fish. In this article, we described the complete mitogenome of and reconstructed the phylogenetic relationship of the relative species of Gobionellinae. The genome is 16,501 bp in length including 13 protein-coding, two ribosomal RNA, 22 transfer RNA genes, as well as a putative control region and an L-strand replication origin. The overall base composition is 28.1%, 27.0%, 28.0% and 16.9% for A, T, C and G, respectively. This result is expected for better understanding the systematic evolution of the genus and further phylogenetic study of Gobiiformes.
暗体三齿虾虎鱼体型小且一年内成熟，是一种很好的模式生物。以往的研究主要集中在年度繁殖周期、社会行为和生活史方面，但关于这种虾虎鱼类线粒体基因组和系统发育进化的信息很少。在本文中，我们描述了暗体三齿虾虎鱼的完整线粒体基因组，并重建了虾虎鱼亚科相关物种的系统发育关系。该基因组长度为16,501 bp，包括13个蛋白质编码基因、两个核糖体RNA基因、22个转运RNA基因，以及一个假定的控制区和一个L链复制起点。A、T、C和G的总体碱基组成分别为28.1%、27.0%、28.0%和16.9%。这一结果有助于更好地理解暗体三齿虾虎鱼属的系统进化以及虾虎鱼目进一步的系统发育研究。
