Chaves de identificação | Morfologia | Morfometria
Espinhos dorsais (total) : 0; Raios dorsais moles (total) : 69 - 80; Raios anais moles: 59 - 64. Head oval-shaped dorsally; snout broadly rounded; eyes laterally placed. Frontal fontanelle is long and narrow; occipital fontanelle small and oval-shaped. Supraorbital and `dermosphenotic' bones partially reduced (especially the latter) and distantly set. Pectoral spine short and straight; outer side with strong downward serrations. gill rakers short and distantly set. Suprabranchial organ greatly reduced. Openings of the secondary sensory canals display a regular pattern.
