The leafhopper genus Eurhadina Haupt, 1929 belongs to the tribe Typhlocybini of subfamily Typhlocybinae (Hemiptera: Auchenorrhyncha: Cicadellidae). Currently, genus Eurhadina includes 3 subgenera, Eurhadina Haupt 1929, Singhardina Mahmood 1967, Zhihadina Yang & Li 1991. A total of 20 valid species of subgenus Eurhadina have been described in the Nearctic and Palaearctic region and the subgenus Singhardina includes 57 species in the Oriental and Palaearctic region (Huang & Zhang 1999, Dworakowska 2002). The subgenus Zhihadina includes only 1 species from China (Yang & Lee, 1991). So far, four species of subgenus Eurhadina were recorded in the Korean Peninsula (Kwon & Huh 2001): Eurhadina (Eurhadina) betularia Anufriev, 1969, E. (E.) koreana Dworakowska, 1971, E. (E.) pulchella (Fallen, 1806), and E. (E.) wagneri Dworakowska, 1969. The majority of species belonging to the subgenus Eurhadina are difficult to distinguish by external appearance because the color patterns of the forewings are very similar among species.
叶蝉属Eurhadina Haupt，1929属于小叶蝉亚科（半翅目：头喙亚目：叶蝉科）的小叶蝉族。目前，Eurhadina属包括3个亚属，即Eurhadina Haupt 1929、Singhardina Mahmood 1967、Zhiadina Yang & Li 1991。在新北界和古北界共描述了20种有效的Eurhadina亚属物种，Singhardina亚属在东洋界和古北界包括57种（Huang & Zhang 1999，Dworakowska 2002）。Zhiadina亚属仅包括来自中国的1个物种（Yang & Lee，1991）。到目前为止，在朝鲜半岛记录了4种Eurhadina亚属物种（Kwon & Huh 2001）：白桦Eurhadina（Eurhadina）betularia Anufriev，1969、朝鲜E.（E.）koreana Dworakowska，1971、美丽E.（E.）pulchella（Fallen，1806）和瓦氏E.（E.）wagneri Dworakowska，1969。Eurhadina亚属的大多数物种很难通过外观区分，因为前翅的颜色模式在物种之间非常相似。
