Eleven species of the genus Pristipomoides were examined on the basis of external and internal characteristics. A new and unique characteristic is described by which this genus can be distinguished from all other genera of the Etelinae, namely, a lack of congregated scales (>6) on the upper part of the cleithrum. The genus Pristipomoides is divided into two subgenera, Pristipomoides and Platyinius, on the basis of distinct features, such as the length of the last dorsal and anal ray, and the structure of hypural, prootic, basioccipital, exoccipital, and first anal pterygiophore. Pristipomoides typus, P. multidens, P. filamentosus, P. flavipinnis, P. auricilla and P. sieboldii of the Indo-Western Pacific belong to the subgenus Pristipomoides. Pristipomoides zonatus and P. argyrogrammicus of the Indo-Western Pacific and P. macrophthalmus, P. aquilonaris and P. freemani of the Western Atlantic are placed in the subgenus Platyinius. Tropidinius which P. zonatus and P. argyrogrammicus were previously recognized as belonging to is a junior synonym of Apsilus (subfamily Apsilinae).
