Original description: Lethrinus atkinsoni Seale, 1910 - Type locality: Balabac Island, Philippines.
Eastern Indian Ocean, western Pacific: Myanmar and Indonesia east to Mariana Islands and Cook Islands, north to southern Sea of Japan, south to northern Australia and New Caledonia.
Inhabits seagrass beds and sandy areas of lagoons and outer reef slopes. Found singly or in schools. Feeds mainly on crustaceans, mollusks, and fish. Marketed fresh. Gonochorism is inferred for this species as sizes of males and females overlapped and male gonad morphology is typical of secondarily derived testes. Juvenile hermaphroditism is exhibited by this species.
Lethrinus laticaudis (Alleyne & Macleay, 1877) - Reported from New Caledonia. Head brown or yellow with blue dots on cheeks and short blue stripes radiating in front and behind the eye, sometimes a number of blue cross stripes between the eyes.
Lethrinus mahsena (Fabricius, 1775) - Reported from Red Sea; Western Indian Ocean: East Africa, Persian Gulf, Socotra, Aldabra, Seychelles, Madagascar and Mascarenes east to Sri Lanka.
