Etymology: Boulengerella: From George Albert Boulenger (1858-1937); he revised the works of Günther about Percoidei (Ref. 45335).
Eponymy: George Albert Boulenger (1858–1937) was a Belgian-British zoologist at the British Museum, London.

Short description Claves de identificación | Morfología | Morfometría

Espinas dorsales (total) : 0; Radios blandos dorsales (total) : 10 - 11; Espinas anales: 0; Radios blandos anales: 9 - 11; Vértebra: 48 - 49. The location of the dorsal fin base distinctly anterior to the vertical through the anal fin origin distinguishes this species from all ctenoluciids except B. lucius and B. xyrekes, from which it can be distinguished by the discrete black spot on the basal portions of the caudal fin rays, and also by different pigmentation on the body.

Usually inhabits areas with rapid water, always on the surface, behind obstacles like rocks and logs (Ref. 54653). Some small-sized individuals occur in calmer waters such as lakes, small bays (Ref. 54653). Solitary or forms small schools (Ref. 54653). A carnivorous fish with preference on fish (Ref. 54653).
