Very little is known of Epinephelus bilobatus. It occurs in isolated areas and may have been confused with similar species (reticulated complex). It is currently assessed as Data Deficient, but should be re-evaluated as more information becomes available.

Geographic Range [top]

Range Description:Epinephelus bilobatus is an eastern Indian Ocean species known only from Western Australia (Port Wolcott 20°39'S to Yampi 16°08'S). It was illustrated in colour as Epinephelus maculatus by Allen (1985) and Sainsbury et al. (1985). This species has been much confused with other 'reticulated groupers' in the literature, and many museum specimens have been misidentified. G. Allen identified six individuals in Raja Ampat (Indonesia) in 2002 and 35 specimens in 2006 at Fak Fak-Kaimana (Irian Jaya).
