Diagnosis
ReferenceDiagnosis
W. Schwarzhans 2003Thin, elongated and fragile otoliths with a
length:height index of 1.7 to 1.9. The rostrum is sharp
and long; no antirostrum or excisura are present. The
postdorsal angle is prominent, the predorsal angle is
almost absent. The sulcus is supramedian, long and
narrow; the caudal tip is reaching very close to the
posterior tip of the otolith and is connected with it by
a small depression.
