): Otolith smaller than usual for the genus, with round outline and without distinct predorsal lobe; OL:OH = 1.05. All rims smooth and rather regularly curved. Inner face almost flat, with median sulcus. Ostial and caudal colliculi small, terminating very close to anterior and posterior tips of otolith; pseudocolliculum short. CCL:OCL = 0.95; TCL:PCL = 2.8. Dorsal depression indistinct; ventral furrow distinct, moderately close to ventral rim.
