Tanytarsini is a large tribe of Chironomidae with at least 11 recorded marine species grouped in three genera. In this study, we performed a phylogenic analysis using molecular data from 13 Tanytarsini genera, including all Japanese marine species in a large tribe of Chironominae, to estimate their phylogenetic positions and evolutionary history. The phylogenetic reconstruction grouped the marine species in two clades. One clade was composed of five marine Tanytarsus and two marine Pontomyia species within a larger clade of Tanytarsus. Pontomyia is considered to have morphologically specialized and adapted to marine environments by rapid evolution, although it formed a clade with Tanytarsus. The only one species of Tanytarsus, T. pelagicus, clustered as a member of the second clade, which was mainly composed by species of the genus Paratanytarsus. Thus, we redescribe T. pelagicus as Paratanytarsus pelagicus.
类摇蚊族是摇蚊科中的一个大族群，至少有 11 种已记录的海洋物种分属于三个属。在这项研究中，我们使用来自 13 个类摇蚊族属的分子数据进行了系统发育分析，包括在一个大型摇蚊科大族群中的所有日本海洋物种，以估计它们的系统发育位置和进化历史。系统发育重建将海洋物种分为两个分支。一个分支由五个海洋类摇蚊属和两个海洋 Pontomyia 属组成，属于更大的类摇蚊属分支。Pontomyia 被认为通过快速进化而具有形态特化和适应海洋环境的特征，尽管它与类摇蚊形成了一个分支。唯一的一个类摇蚊属物种 Tanytarsus pelagicus 聚类为第二个分支的成员，该分支主要由 Paratanytarsus 属的物种组成。因此，我们将 T. pelagicus 重新描述为 Paratanytarsus pelagicus。
