New meristic and descriptive data of Eckström's topknot Zeugopterus regius (Pleuronectiformes: Scophthalmidae) from Galician waters (north-west Spain) is presented. The presence of a higher number of dorsal and anal fin rays as well as more than one elongated ray in the dorsal fin is described for the first time. Furthermore, other distinctive characters poorly known as the fringe-like appearance of first dorsal ray and numbers of distinct round-blotches on the body are reviewed. Length distribution and length–weight relationship are also shown.
