Abstract
A single specimen of Onigocia grandisquama (Regan, 1938) (Platycephalidae) from Kuantan, Pahang, Malaysia (east coast of Peninsular Malaysia) represents the first record of the species from Malaysia, previous records from the South China Sea having been restricted to Thailand. Four specimens of Soleichthys siammakuti Wongratana, 1975 (Soleidae) from Kuantan and Kota Kinabalu (Borneo), Malaysia and Negros (the Philippines) represent the first specimen-supported records of the species from those regions, the species having previously been collected only from the type locality (northern Gulf of Thailand).
