Eastern Indian Ocean: known only from Western Australia. Was illustrated in color as Epinephelus maculatus by Allen (1985, Ref. 1677) and Sainsbury et al. (1985, Ref. 3131). This species have been much confused with other 'reticulated groupers' in literature, and many museum specimens have been misidentified.
