根据 1993-2019 年生物多样性项目的数据和文献综述，介绍了泰国各地不同淡水生态系统的双翅目桡足类动物的多样性、分布和清单。泰国是世界上双子类动物群最多样化的国家之一，在 2150 个地点鉴定出 42 个物种（4962 个样本）。 Mongolodiaptomus 的物种丰富度最高，有 10 种，其次是 Tropodiaptomus，有 7 种。其中，八个类群（Arctodiaptomus sp.、Mongolodiaptomus pectinidactylus、Neodiaptomus meggitti、Tropodiaptomus hebereri、T. lanaonus、T. oryzanus、T. ruttneri 和 Paradiaptomus greeni）是泰国动物群中的新物种。稀有的 P. greeni 主要分布在非洲，也是东南亚的新纪录。最常见的物种是 Mongolodiaptomus botulifer、Phyllodiaptomus praedictus、M. calcarus、M. dumonti、M. malaindosinensis、Vietodiaptomus blachei、Phyllodiaptomus christineae、Eodiaptomus sanoamuangae、Neodiaptomus yangtsekiangensis、E. draconisignivomi、T. vicinus 和 Heliodiaptomus elegans。十二种似乎是泰国特有的，八种仅出现在属于湄公河流域下游的国家（泰国、柬埔寨、老挝和越南）。泰国双翅目动物的独特之处在于同一地点有四到七个物种高度共存。提供了对所记录物种的分类地位的评论。此外，还讨论了 Mongolodiaptomus malindosinensis 的分类学有效性。
The diversity, distribution, and checklist of diaptomid copepods from various freshwater ecosystems throughout Thailand are presented, based on data from our biodiversity projects during 1993–2019 and literature reviews. Thailand has one of the most diversified diaptomid fauna in the world, with 42 species identified from 2150 localities (4962 samples). Mongolodiaptomus has the highest species richness with ten species, followed by Tropodiaptomus with seven species. Among these, eight taxa (Arctodiaptomus sp., Mongolodiaptomus pectinidactylus, Neodiaptomus meggitti, Tropodiaptomus hebereri, T. lanaonus, T. oryzanus, T. ruttneri, and Paradiaptomus greeni) are new to the fauna of Thailand. The rare P. greeni, which predominantly occurs in Africa, is also a new record for Southeast Asia. The most frequently encountered species were Mongolodiaptomus botulifer, Phyllodiaptomus praedictus, M. calcarus, M. dumonti, M. malaindosinensis, Vietodiaptomus blachei, Phyllodiaptomus christineae, Eodiaptomus sanoamuangae, Neodiaptomus yangtsekiangensis, E. draconisignivomi, T. vicinus, and Heliodiaptomus elegans. Twelve species appear to be endemic to Thailand, and eight species occur only in the countries belonging to the lower Mekong River Basin (Thailand, Cambodia, Laos, and Vietnam). The uniqueness of the Thai diaptomids is a high degree of co-occurrence of four to seven species in the same localities. Comments on the taxonomic status of the species recorded are provided. In addition, the taxonomic validity of Mongolodiaptomus malaindosinensis is discussed.
