Species of the synaphobranchid eel genera Dysomma and Dysommina from Taiwan are reviewed. A total of eight species in Dysomma and one species in Dysommina are recognized. A new Dysomma species is described based on four specimens collected from off Taiwan. It differs from its Taiwanese congeners in having 137–139 total vertebrae, pectoral fin well-developed, 2 intermaxillary teeth, 4 compound teeth on vomer, 40–48 total lateral-line pores, the last at about middle of body, and a uniform brownish color. A key to all species in these two genera in Taiwan is provided.
