Species of the Old World mirine plant bug genus Eurystylus Stål (the Head Bugs) in Japan and Taiwan are reviewed. Four species are currently recognized. Two new species are diagnosed and described: E. ryukyus n. sp. (from SW Japan and Taiwan) and E. jingfui n. sp. (Taiwan). Two known species, E. coelestialium (Kirkaldy) and E. sauteri Poppius, are diagnosed; new distributional records are added for the latter. Two keys are provided to aid the identifications of (1) Eurystylus and four related genera and (2) the species of Eurystylus known from Japan and Taiwan. The phylogenetic relationships of Eurystylus with the assumed related genera are discussed. Eurystylomorpha Poppius is synonymized with Eurystylopsis Poppius, and a new combination, Eurystylopsis crassicornis (Poppius), is accordingly proposed.
对日本和台湾地区的旧大陆姬缘蝽属（Eurystylus Stål，即头蝽）昆虫种类进行了综述。目前共识别出4个物种。诊断并描述了2个新物种：琉球宽缘蝽（E. ryukyus n. sp.，分布于日本西南部和台湾）和景氏宽缘蝽（E. jingfui n. sp.，台湾特有）。对2个已知物种，即广宽缘蝽（E. coelestialium (Kirkaldy)）和梭德氏宽缘蝽（E. sauteri Poppius）进行了诊断，并补充了后者的新分布记录。提供了2个检索表，以帮助鉴定（1）宽缘蝽属及4个相关属，以及（2）日本和台湾已知的宽缘蝽属物种。讨论了宽缘蝽属与假定相关属的系统发育关系。将Poppius的Eurystylomorpha与Eurystylopsis Poppius同义，并相应地提出了一个新组合，即粗角宽缘蝽（Eurystylopsis crassicornis (Poppius)）。
