Diagnosis genera. The genus Otolithoides is distinguished from other Sciaenidae genera by the following combination of features: (1) swimbladder with one diverticulum on each side, attached near the posterior end; (2) vertebrae 12+13, with the third bearing a pair of ventral apophyses that do not meet below; (3) interorbital width 26–33% of head length; (4) lateral line scales cycloid, usually covered with small subsidiary scales; (5) second anal spine weak; (6) sagitta with a large pouched “head” and a “tail” only slightly curved and ending in a disc; and (7) absence of predorsal bones (Trewavas, 1977).
Remarks on genus: The genus Pama (Fowler, 1933) is not recognized, as the generic diagnostic characters such as the swimbladder and sagitta type which of its type species, Otolithoides pama, are the same as those of Otolithoides biauritus. Examination of the syntypes and lectotypes of O. brunneus (Day) and O. biauritus (Cantor) confirmed that the former is a synonym of the latter (Talwar, 1995).
