尤尼尼达目的淡水贻贝是淡水栖息地的关键组成部分，具有重要的生态功能和服务。不幸的是，这些双壳类动物是世界上受威胁最严重的淡水类群之一。然而，保护规划和管理受到分类问题和缺乏详细生态数据的阻碍。这凸显了尤尼尼达内部系统学和进化关系领域迫切需要取得进展。这项研究提出了迄今为止最全面的Unionida家族（即Unionidae）的系统发育。该系统发育基于 46 属 70 个物种的 1032 bp (COI + 28S) 组合数据集，其中 7 个属首次测序。由此产生的系统发育将 Unionidae 分为 6 个受支持的亚科和 18 个部落，其中 3 个是首次命名（即 Chamberlainiini nomen novum、Cristariini nomen novum 和 Lanceolariini nomen novum）。传统系统发育研究中使用的选定形态、解剖和行为特征的研究补充了分子分析。没有任何单一的形态、解剖或行为特征可以在亚科水平上进行诊断，也很少有在部落水平上有用的。然而，在亚科内，可以根据这些字符的子集来识别许多部落。还介绍了每个亚科和部落的地理分布。本研究为这些特殊类群的系统学提供了重要进展，对未来的生态和保护研究具有重要意义。 (C) 2016 Elsevier Inc. 保留所有权利。
Freshwater mussels of the order Unionida are key elements of freshwater habitats and are responsible for important ecological functions and services. Unfortunately, these bivalves are among the most threatened freshwater taxa in the world. However, conservation planning and management are hindered by taxonomic problems and a lack of detailed ecological data. This highlights the urgent need for advances in the areas of systematics and evolutionary relationships within the Unionida. This study presents the most comprehensive phylogeny to date of the larger Unionida family, i.e., the Unionidae. The phylogeny is based on a combined dataset of 1032 bp (COI + 28S) of 70 species in 46 genera, with 7 of this genera being sequenced for the first time. The resulting phylogeny divided the Unionidae into 6 supported subfamilies and 18 tribes, three of which are here named for the first time (i.e., Chamberlainiini nomen novum, Cristariini nomen novum and Lanceolariini nomen novum). Molecular analyses were complemented by investigations of selected morphological, anatomical and behavioral characters used in traditional phylogenetic studies. No single morphological, anatomical or behavioral character was diagnostic at the subfamily level and few were useful at the tribe level. However, within subfamilies, many tribes can be recognized based on a subset of these characters. The geographical distribution of each of the subfamilies and tribes is also presented. The present study provides important advances in the systematics of these extraordinary taxa with implications for future ecological and conservation studies. (C) 2016 Elsevier Inc.
