Diagnosis

Reference	Diagnosis
W. Schwarzhans 2003	A fossil otolith based genus of the family Argentinidae with the following characters. The otoliths are elongated, oval in outline and rather thin. The dorsal rim is gently curved, shallow and with or without a postdorsal angle. The ventral rim is more deeply curved, smooth and with a rounded medioventral angle located just slightly in front of the middle. The rostrum is massive but it is not very long. Excisura and antirostrum are missing. The sulcus is long, located supramedian, with a long and narrow cauda and a shorter and widened ostium. The dorsal field shows a narrow, but long dorsal depression, whereas the ventral field is completely smooth and without a ventral furrow.
