Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| A. M. Murray et al. 2016 | Differs from Lycoptera, Tanolepis, Paralycoptera, and Xiaxiaichthys by having the supraorbital sensory canal ending in the frontal not the parietal; differs from Hiodontiformes (Eohiodon, Hiodon) by lacking a recurved spine on the posterodorsal part of the opercle. Within the Osteoglossiformes, differs from Osteoglossidae by having tubular (instead of flat, broad) nasal bones, lacking reticulations on the scales, and lacking an enlarged pectoral fin ray and differs from mormyroids and
notopterids by having a distinct dorsal process on the opercle (rather than a flattened or truncated dorsal edge) and lacking other specializations of those groups (such as long dorsal fin confluent with caudal fin in notopterids and the rounded snout or elongate jaw bones of mormyroids) |
