Cable's goby is a species of goby endemic to reefs around the Galápagos Islands. This species grows to a length of 7 centimetres (2.8 in) SL. This species is the only known member of its genus. The specific name honours the United States Government biologist Louella E. Cable (1900–1986), who illustrated this goby for the describer Isaac Ginsburg, and drew his attention to its separated ventral fins.
