This study describes a new genus and two new species of Tanaidacea that were collected from the Singaporean exploratory area (OMS) of the polymetallic nodule fields in the eastern end of the Clarion-Clipperton Fracture Zone, Pacific Ocean. The descriptions are based on material collected during the research cruise ABYSSLINE II, which was conducted in the year 2015, covering abyssal depths of 4041–4227 m. These new species are paratanaoideans belonging to the genera Unispinosus n. gen. and Portaratrum Guerrero-Kommritz, 2003 of the family incertae sedis.
