Diagnosis from Day 2002, p. 335: "Distinguished from other Eocene sparids by a robust jaw with large, conical teeth. Ethmoid dorsal margin is depressed directly anterior to the ethmoid±frontal suture. Deep-bodied form with a length to width ratio of 3:1. The supraneural formula appears to be 0/0 + 0/2 + 1/1; and the anterodorsal processes of the supraneurals overlap. Hypurals are separate. Caudal ®n is of low aspect ratio. Formula of the dorsal fin XII + 9; anal fin III + 9."
