Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| A. López-Arbarello and A. M. Zavattieri 2008 | The following diagnosis is based on a combination of primitive and advanced characters: body depth is 3.5· in SL; anterior and posterior dermopterotics present; anterior supraorbital bone extends beyond the anterior border of the parietal; origin of anal fin opposite to end of dorsal fin; anal fin with two basal fulcra; caudal fin with six dorsal and one ventral basal fulcra; nine dorsal and five ventral precaudal median scutes. | |
