A. López-Arbarello and A. M. Zavattieri 2008 | Among the following combination of characters, an asterisk (*) indicates synapomorphies: small actinopterygians up to 120 mm in total length (TL); body depth 2–3.5· in standard length (SL; the length of a fish measured from the tip of the snout to the base of the
caudal fin); pelvic fins closer to anal than to pectoral fins; dorsal and anal fins of similar size; incomplete dorsal ridge of spine-like scales between skull and dorsal fin*; a series of median scutes on dorsal and ventral midlines from end of dorsal to caudal fin and from end of anal to caudal fin respectively; flank scales approximately three times deeper than long; scales with straight posterior border, elevated central region and marginal concentric ridges of ganoine*. | |
