Etymology: Brachyhypopomus: Greek, brachys, eia = short + Greek, hypo = under + Greek, poma, -atos = cover (Ref. 45335); bombilla: Named in memory of Pablo Errandonea, who chose to call this fish bombilla. Bombilla refers to the local name for metal straw used to drink mate, a popular herbal infusion whose shape resembles the body shape of this species..

Short description
Identification keys | Morphology | Morphometrics
Anal soft rays: 155 - 190. Can be differentiated from all congeners by the following combination of characters: pigmentation pattern of body consisting of scattered dark brown pigmentation over a brown
background, more dense on the dorsal half of the body; epidermal laterosensory canals
pigmented; head depth 61.8-76.4% of HL; caudal filament length 6.5-16.6% of ; 55-190 anal-fin rays; fourth supraorbital pore dorsal and half-way between posterior nares and anterior
margin of orbit; upper jaw slightly longer than lower jaw; a cartilaginous mesocoracoid; slender anterodorsal process of the maxilla; all branchiostegal rays of equal size, none hook-like (Ref. 75964).
Facultative air-breathing in the genus (Ref. 126274); Occurs in swamps, slow moving river edges and standing water, often with dense vegetation (Ref. 75964).
