The genus Förster, 1869 is first recorded from Taiwan. One previously described species, Uchida, 1930, is newly recorded from Taiwan. Six new species, , , , , , and , are described and can be distinguished from their congeners primarily based on color pattern, mandibular teeth, propodeal carinae, fore wing length and venation, ocellar and first metasomal tergite measurements, and flagellomere counts. Illustrations of the male genitalia and a diagnostic key to the Taiwanese species are provided. DNA-based species delimitations are provided as supporting evidence for four new species. In a COI-based phylogeny sampling 31 operative taxonomic units of and similar genera, the genus was not resolved as a monophyletic group. Additionally, the barcode showed limitations in distinguishing some morphospecies, indicating the need for further evaluation of -based species delimitation in this genus.
福斯特属（Förster，1869）首次在台湾被记录。一个先前已描述的物种（内田，1930）首次在台湾被新记录。描述了六个新物种，分别为[此处六个新物种的具体名称缺失]，它们可主要基于体色模式、下颌齿、并胸腹节隆线、前翅长度和脉序、单眼和第一腹节背板测量值以及鞭节数量与同属其他物种相区分。提供了雄性生殖器的图示以及台湾该属物种的检索表。基于DNA的物种界定为四个新物种提供了支持证据。在一个基于细胞色素氧化酶亚基I（COI）的系统发育分析中，对该属及类似属的31个操作分类单元进行了采样，福斯特属未被解析为单系类群。此外，COI条形码在区分一些形态物种时存在局限性，这表明需要对该属基于COI的物种界定进行进一步评估。
