The blackeye goby (Rhinogobiops nicholsii) is the only species classified under the monotypic genus Rhinogobiops.
In 1960, James E. Böhlke and C. Richard Robins synonymized Rhinogobiops with Coryphopterus, though they noted that it differed from other members of the latter in the number of fin rays and scales and should be treated as a subgenus [REF].
