Pectoral fins extending to VO1 or VO2. Ventral fins reaching origin of anal fin. Base of adipose fin well behind end of base of anal fin. Dn small and rounded; Vn absent. A very small Op1 below angle of mouth; Op2 much larger and about at level of ventral margin of orbit. PLO on lateral line and in contact with posterior dorsal margin of operculum. PVO1 in advance of vertical through PO2, midway between ventral base of pectoral fin and ventral profile; PVO2 at lower base of pectoral fin. Five PO; PO3 and PO4 highly elevated, PO4 about 1 time its own diameter below lateral line. Four VO; VO1 remarkably elevated. VLO midway between base of pectoral fin and lateral line.
