1, 2, 3, 4 cartilaginous at tips; ceratobranchial
5 completely cartilaginous and fused with lower pharyngeal plate; lower pharyngeal plate ossified, possessing large conical teeth with slightly recurved tips.
Hyobranchial apparatus: Comprising median unpaired glossohyal, basihyal, three basibranchials and urohyal; and bilaterally paired dorsal and ventral hypohyals, anterior and posterior ceratohyals, interhyal, six branchiostegal rays, three hypobranchials, five ceratobranchials, four epibranchials and three pharyngobranchials (Fig.
Ceratobranchials elongate, arcuate, ventral surface bearing process for attachment of pharyngeal musculature.
Hyoid and gill arches not distinct from other Atherinidae; fifth ceratobranchials
fused, characteristic of new genus in combination with other attributes (Fig.
Cartilaginous basibranchial and ceratobranchials
