2013年、2015年和2017年至2019年，韩国汉江口爆发了带状蠕虫，对当地的玻璃鳗鱼渔业造成了损害。汉江带状蠕虫（Yininemertes pratensis, Sun & Lu, 1998）不仅与正型和准型标本的形态特征进行了比较，而且与中国长江口附近新采集的形态标本的DNA序列进行了比较。利用6个基因标记（18S rRNA、28S rRNA、组蛋白H3、组蛋白H4、16S rRNA和COI）的序列，根据从公共数据库中获得的序列推断出pratensis在其他异源动物中的系统发育位置。这一分析坚定地将pratensis确定为Apatronemertes albimaculosa Wilfert & Gibson（1974）的近亲，后者在世界各地装有热带淡水植物的水族箱中以及巴拿马的野生环境中都有报道。
Outbreaks of ribbon worms observed in 2013, 2015, and 2017-2019 in the Han River Estuary, South Korea, have caused damage to local glass-eel fisheries. The Han River ribbon worms have been identified as Yininemertes pratensis (Sun & Lu, 1998) based on not only morphological characteristics compared with the holotype and paratype specimens, but also DNA sequence comparison with topotypes freshly collected near the Yangtze River mouth, China. Using sequences of six gene markers (18S rRNA, 28S rRNA, histone H3, histone H4, 16S rRNA, and COI), the phylogenetic position of Y. pratensis was inferred among other heteronemerteans based on their sequences obtained from public databases. This analysis firmly placed Y. pratensis as a close relative to Apatronemertes albimaculosa Wilfert & Gibson, 1974, which has been reported from aquarium tanks containing tropical freshwater plants in various parts of the world as well as a wild environment in Panama.
