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.
東印度洋: 已知只來自西澳大利亞了。 被艾倫 (1985, 參考文獻 1677) 與塞恩斯伯里等人舉例顏色如 花點石斑魚〔Epinephelus maculatus〕 。 (1985, 參考文獻 3131). 這種在文獻中多曾經另外地互相混淆 '網狀的鱸科魚類' ,而且許多博物館標本曾經辨認錯。
