Diagnosis
ReferenceDiagnosis
C.-H. Lin et al. 2017This species is characterised by nearly rectangular and thickset otoliths. The anterior rim of the otoliths is blunt, which makes the highest part of the otolith at the anterior portion. The dorsal rim undulates, with the middle part being concave, while both the anterior and posterior parts are higher and angular. The posterior rim is rounded, smaller than the anterior one. The sulcus is lled with two large elongate collicula.
