Hydromermis viridis n. sp. and Hydromermis gastroviridis n. sp. are described from June and August emerging imagos, respectively, of Endochironomus subtendens (Townes) in Lake Itasca, Clearwater County, Minnesota. The position of the mouth, shape of the posterior end, structure and size of the spicule, absence of an excretory pore, arrangement of male tail musculature, and measurements separate the new species form other species of Hydromermis as well as from one another. The 2 species are placed in the genus Hydromermis though having a rounded tail and only 6 hypodermal cords at midbody. An anomalous double vagina condition is reported in H. viridis.
绿色水线虫新种（Hydromermis viridis n. sp.）和胃绿色水线虫新种（Hydromermis gastroviridis n. sp.）分别描述自明尼苏达州克利尔沃特县伊塔斯卡湖中的亚端摇蚊（Endochironomus subtendens，汤氏）6月和8月羽化的成虫。口的位置、后端形状、交合刺的结构和大小、排泄孔的缺失、雄性尾部肌肉组织的排列以及测量数据将这两个新物种与水线虫属的其他物种区分开来，同时也将它们彼此区分。这两个物种虽具有圆形尾部且虫体中部仅有6条皮下索，但仍被归入水线虫属。在绿色水线虫中报道了一种异常的双阴道情况。
