The species is identifiable by its fusiform otoliths, which have a largely blunt anterior rim and a well-marked posterior angle. The dorsal rim is elevated and possesses a blunt antero-dorsal bulge, forming the highest point of the otoliths. The ventral rim is gently curved, and all margins are smooth. The otoliths are thick and possess convex inner and outer faces (

). A straight, wide, and well-divided sulcus occupies nearly the entire length of the inner face in the central region of the otoliths. The sulcus does not open to the margins. The ostium is notably elongate and extends over one-third of the sulcus length, and it is very slightly narrower than the short, rectanglar cauda. Above the crista superior, there is a shallow, elongate dorsal depression.
The massive, robust otoliths of this new species share many characters with those of “
