Adult worms that belong to Carassotrema Park 1938 and Elonginurus Lu, 1955 were found in the intestine of Carassius gibelio Bloch, 1782 from the southern Russian Far East and Mugil cephalus Linnaeus, 1758 from northern Vietnam, respectively. Morphometric parameters, geographic location and host species composition of these worms correspond to Carassotrema koreanum Park 1938, which is a known parasite of cyprinid fish in Korea, Japan and China, and Elonginurus mugilus Lu, 1955, first described from M. cephalus in China. The validity of Carassotrema ginezinskajae Kulakova, Ha Ky, 1976, a synonym of C. koreanum, first described from Spinibarbichthys denticulatus Oshima, 1926 in Vietnam, supported the morphometric data. Phylogenetic analysis based on combined ITS2 ribosomal DNA (rDNA) and 28S rRNA indicated that C. koreanum and E. mugilus belong to the subfamily Waretrematinae and are closely related to the genera Skrjabinolecithum and Parasaccocoelium, respectively. Species similarity, revealed through molecular analysis, agreed with the generic diagnoses for Parasaccocoelium and Elonginurus, as well as for Carassotrema and Skrjabinolecithum.
在俄罗斯远东地区的鲫鱼（Carassius gibelio Bloch）和越南北部的梭鱼（Mugil cephalus Linnaeus）的肠道中分别发现了属于 Carassotrema Park 1938 和 Elonginurus Lu，1955 的成虫。这些蠕虫的形态参数、地理位置和宿主物种组成与 Carassotrema koreanum Park 1938 相对应，后者是韩国、日本和中国鲤鱼的已知寄生虫，而 Elonginurus mugilus Lu，1955 则是首次在中国梭鱼中描述的蠕虫。支持 Carassotrema ginezinskajae Kulakova，Ha Ky，1976 的有效性，它是越南首先从 Spinibarbichthys denticulatus Oshima，1926 描述的 Carassotrema koreanum 的同义词，其形态数据得到了支持。基于 ITS2 核糖体 DNA（rDNA）和 28S rRNA 的联合分析表明，Carassotrema koreanum 和 E. mugilus 属于 Waretrematinae 亚科，分别与 Skrjabinolecithum 和 Parasaccocoelium 属密切相关。通过分子分析揭示的物种相似性与 Parasaccocoelium 和 Elonginurus 的属诊断以及 Carassotrema 和 Skrjabinolecithum 的属诊断一致。
