A. López-Arbarello and A. M. Zavattieri 2008An actinopterygian distinguished by the following combination of primitive and advanced characters: body depth three times in SL; anterior and posterior dermopterotics present; anterior supraorbital does not extend beyond the anterior border of the parietal; short infraorbital process of preoperculum; pectoral fin with one stout basal fulcrum and nine rays; posterior half of dorsal fin opposite to anterior half of anal fin; dorsal fin with three basal fulcra and 16 rays; anal fin with two basal fulcra; caudal fin with nine dorsal and three ventral basal fulcra; seven dorsal and four ventral precaudal median scutes; dorsal ridge with more than ten spine-like scales, starting almost immediately behind the skull.
