Nine species of Parabothus are currently recognized. A new bothid flatfish, Parabothus rotundifrons, is described from six specimens. It is considered as a species of Parabothus because of caudal skeleton structure, moderate width of concave interorbital space in male and moderate body depth in both male and female. P. rotundifrons is easily separable from other congeners by having a lowest number of scales in the lateral line (48-58), biserial teeth on the upper jaw, steep dorsal profile of the head, 8-9 non-serrate gill rakers on the low limb of the first arch, perforated membrane of dorsal and anal fins. P. rotundifrons is known from the Saya de Malha Bank, Mascareignes Plateau, Indian Ocean.
