Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| L. J. Bryant 1987 | Very large amiid (standard length [tip of snout to base of caudal fin] may exceed 160 cm). Differs from all other known amiids in having central trunk vertebrae ventrolaterally concave, anterior maxilla circular in cross section. Deep pit for articulation of premaxilla overlapping the most anterior maxilla alveolus. Dentary with 14 teeth; horizontal ramus wider than deep. Cleithrum lacking sculpture, forming a 90 degree angle between dorsal and ventral arms. Basioccipital width more than twice its height. Differs from Enneles in having fused infraorbitals 4 and 5, and lacking the supramaxilla. Differs from all other amiids except Pachyamia and Enneles in having carinate teeth and alveoli with crenulated borders. |
