白蚁（等翅目：鼻白蚁科）是我国最具经济价值的地下白蚁属之一，部分物种是成功的入侵者。然而，尽管其重要的害虫地位，许多已命名的黄蚁物种的分类有效性尚不清楚。在这项研究中，我们回顾了属内所有命名的物种，并调查了支持每个命名物种有效性的证据。根据它们最初描述的区域，对物种进行了系统的审查：东南亚、印度、中国、非洲、新热带和澳大利亚。我们估计，在目前被公认的命名规则所描述的69个物种中，只有21个分类群有可靠的有效性证据，44个分类群的命名状态不确定，其余的物种名称应该同义或不可用。具有高度入侵性的物种由于独立的区域描述，可以在额外的初级同义词下已知。绝大多数物种的分子数据是稀缺的，需要大量的努力来完成属的分类和系统发育修正。由于黄蚁的广泛分布，我们主张对黄蚁进行综合分类学研究，以确定每个假设物种的分布，提供标本和相应的分子数据，检查原始描述和模式标本（如果有的话），并为每个物种的系统发育定位提供更有力的证据。这项研究体现了白蚁研究的共识和争论，从而确定了许多物种目前的不确定性。本项目旨在成为确定需要更彻底调查的coptoterme物种名称的路线图，作为完成必要修订过程的激励。
Coptotermes Wasmann (Isoptera: Rhinotermitidae) is one of the most economically important subterranean termite genera and some species are successful invaders. However, despite its important pest status, the taxonomic validity of many named Coptotermes species remains unclear. In this study, we reviewed all named species within the genus and investigated evidence supporting the validity of each named species. Species were systematically scrutinized according to the region of their original description: Southeast Asia, India, China, Africa, the Neotropics, and Australia. We estimate that of the currently 69 named species described by accepted nomenclatural rules, only 21 taxa have solid evidence for validity, 44 names have uncertain status, and the remaining species names should be synonymized or were made unavailable. Species with high degrees of invasiveness may be known under additional junior synonyms due to independent parochial descriptions. Molecular data for a vast majority of species are scarce and significant effort is needed to complete the taxonomic and phylogenetic revision of the genus. Because of the wide distribution of Coptotermes, we advocate for an integrative taxonomic effort to establish the distribution of each putative species, provide specimens and corresponding molecular data, check original descriptions and type specimens (if available), and provide evidence for a more robust phylogenetic position of each species. This study embodies both consensus and contention of those studying Coptotermes and thus pinpoints the current uncertainty of many species. This project is intended to be a roadmap for identifying those Coptotermes species names that need to be more thoroughly investigated, as an incentive to complete a necessary revision process.
