Species

Once, three species were placed in this genus, but Gephyroberyx philippinus is now considered to be a synonym of G. darwinii.^[1][2] Based on broadly overlapping morphological features, G. japonicus should also be regarded a synonym of G. darwinii,^[2][3] but both are recognized as valid species by FishBase:^[4]

• Gephyroberyx darwinii (J. Y. Johnson, 1866) (Darwin's slimehead)
• Gephyroberyx japonicus (Döderlein, 1883) (big roughy)
