Description synthétique
Clés d'identification | Morphologie | Morphométrie
Épines dorsales (Total) : 19 - 21; Rayons mous dorsaux (Total) : 13 - 14; Épines anales: 3; Rayons mous anaux: 9 - 12; Vertèbres: 35. Easily distinguished from all other species of the genus by having a row of dark blotches forming a more or less continuous band along the abdominal side, and by having infraorbitals 3 and 4 co-ossified instead of separate. Differs from most Crenicichla species in having a smooth-margined instead of serrated preopercle (Ref. 26677).
Body shape (shape guide): elongated.
