Descrição suscinta Chaves de identificação | Morfologia | Morfometria

Espinhos dorsais (total) : 9; Raios dorsais (total) : 10; Espinhos anais: 2; Raios anais : 9. Body somewhat elongate, the depth contained 3 to 3.2 times in SL. Snout somewhat pointed; a small dermal cirrus at edge of anterior nostril; teeth fused only basally, thus not fully coalesced to form dental plates. Gill rakers 12 or 13.
