A new species of cirri-bearing eel, (Anguilliformes, Ophichthidae), is described based on a specimen collected from the estuary of the Langyang River (Yilan County), northeastern Taiwan. The new species is distinct from all congeners, except and , in possessing a single row of mandibular teeth. differs from in having significantly shorter pectoral fins and fewer vertebrae, and it is distinguished from by its larger head, notably more total vertebrae, and a dorsal fin that originates well behind the gill opening. In the neighbor-joining tree based on COI sequences, the new species forms a distinct monophyletic group; thus, it is clearly separable from congeners both morphologically and genetically. With this addition, there are now 13 species in the genus .
基于从台湾东北部兰阳溪河口（宜兰县）采集的一个标本，描述了一种新的具触须鳗类物种（鳗鲡目，蛇鳗科）。该新物种与所有同属物种不同，除了[具体物种1]和[具体物种2]，其具有一排下颌齿。[新物种名称]与[具体物种1]的区别在于胸鳍明显更短且椎骨更少，与[具体物种2]的区别在于头部更大、总椎骨明显更多以及背鳍起点远在鳃孔之后。在基于COI序列的邻接树中，新物种形成一个独特的单系类群；因此，它在形态和遗传上都明显可与同属物种区分开来。加上这个新物种，该属现在有13个物种。
