In this paper, three species of the macrostomid free-living flatworm genus are described. Two species, Wang & Shi, and Wang & Shi, , were collected from coastal water at Shenzhen, Guangdong Province, China. One species, Wang & Shi, , was collected from Perth, Western Australia and Queenscliff, Victoria, Australia. differs from congeneric species within the genus in the length of the stylet, diameter of stylet opening, and the bend of the stylet. and differ from similar species within the genus in the stylet morphology, position of the female antrum and developing eggs, or presence or absence of the false seminal vesicle. Phylogenetic analysis based on cytochrome c oxidase subunit I (COI) gene shows that and are sister clades on two well-separated branch, and are sister clades on two well-separated branches. Accordingly, both morphological and molecular evidence support , , and as three new species.
本文描述了大口涡虫属的三个物种。两个物种，即Wang & Shi（具体种名未给出）和Wang & Shi（具体种名未给出），采自中国广东省深圳市的沿海水域。一个物种，Wang & Shi（具体种名未给出），采自澳大利亚西部的珀斯和澳大利亚维多利亚州的昆斯克利夫。该物种在口针长度、口针开口直径和口针弯曲度方面与该属内的同属物种不同。另外两个物种在口针形态、雌性生殖窦位置和发育中的卵，或是否存在假精囊方面与该属内的相似物种不同。基于细胞色素c氧化酶亚基I（COI）基因的系统发育分析表明，一个物种和另一个物种在两个明显分开的分支上是姐妹分支，另外两个物种在两个明显分开的分支上是姐妹分支。因此，形态学和分子证据均支持这三个物种为新物种。
