Abstract

The species of the ant genus Strumigenys Smith, 1860 from Southeast Asia are reviewed based on recent sampling efforts as well as unreported historical material from southern mainland China, Japan, Taiwan, Thailand and Vietnam. We report 42 new species records for these regions. A total of 20 species new to science are described: S. anhdaoae sp. nov., S. claviseta sp. nov., S. crinigera sp. nov., S. decumbens sp. nov., S. delicata sp. nov., S. densissima sp. nov., S. doydeei sp. nov., S. fellowesi sp. nov., S. intermedia sp. nov., S. jaitrongi sp. nov., S. liuweii sp. nov., S. longidens sp. nov., S. mediocris sp. nov., S. rongi sp. nov., S. scutica sp. nov., S. strummeri sp. nov., S. xenopilus sp. nov., S. yamanei sp. nov., S. zanderi sp. nov. and S. zhenghuii sp. nov. The descriptions of the existing species S. elegantula (Terayama & Kubota, 1989) and S. nathistorisoc Tang et al., 2019 are revised. Strumigenys formosensis Forel, 1912 syn. nov. is synonymized with S. feae Emery 1895 in the light of recently collected specimens. Three species complexes are created within the S. leptothrix-group: elegantula-complex, leptothrix-complex and zanderi-complex, based on differences in dentition. A new species group, S. nathistorisoc-group, is introduced. The key to Strumigenys of East Asia (as Pyramica) by Bolton is partially revised to accommodate species from these species groups that were described since the publication of the key. Finally, the implication of our results to the region and the current limitation of species groups and complexes of the genus is discussed.

进一步增加了东南亚的金蚁属(蚁科:金蚁科)的知识，描述了20个新种

根据最近的采样工作以及来自中国大陆南部、日本、台湾、泰国和越南的未报告历史材料，对东南亚的蚂蚁属 Strumigenys Smith, 1860 的物种进行了回顾。我们报告了这些地区的 42 个新物种记录。共描述了 20 个科学新物种：S.anhdaoae新种、S. claviseta新种、S. crinigera新种、S. decumbens新种、S. delicata新种、S. densissima新种、S. doydeei新种、S. fellowesi新种、S. intermedia新种、S. jaitrongi新种、S.liuweii新种、S. longidens新种、S. mediocris新种、S. rongi新种、S. scutica新种、S. strummeri新种、S. xenopilus新种、S. yamanei新种、S. zanderi新种和S. zhenghui新种。elegantula (Terayama & Kubota, 1989) 和 S. nathistorisoc Tang et al.根据最近采集的标本，Strumigenys formosensis Forel, 1912 syn.根据牙齿的差异，在 S. leptothrix 群中创建了三个物种群：elegantula 群、leptothrix 群和 zanderi 群。引入了一个新的物种群，即 S. nathistorisoc-群。对博尔顿（Bolton）所著的东亚 Strumigenys（作为 Pyramica）的检索表进行了部分修订，以纳入自该检索表出版以来所描述的这些种群中的物种。最后，讨论了我们的研究结果对该地区的影响以及该属物种群和复合群目前的局限性。

期刊介绍： EJT is a fully refereed, international, fully electronic Open Access journal in descriptive taxonomy, covering subjects in zoology, entomology, botany (in its broadest sense), and palaeontology. EJT-papers must be original and adhere to high scientific (content) and technical (language, artwork, etc.) standards. Manuscripts that are clearly substandard in either of these categories will not be sent out for review. EJT is supported by a consortium of European Natural History Institutes, but its scope is global. Both authorship and geographical region of study need not be European. Authors are, however, strongly encouraged to involve European Natural History collections by consulting material or by depositing specimens (e.g. types and figured material) related to their published paper in the collection of a European Natural History Institute.
