Etymology: Brachyhypopomus:Greek, brachys, eia = short + Greek, hypo = under + Greek, poma, -atos = cover (Ref. 45335); walteri:Named for Walter Heiligenberg in honor of his discoveries in electric fish neurophysiology and behavior made at the Scripps Institute of Oceanography.
Institute of Oceanography. Eponymy: Dr Walter F Heiligenberg (1938–1994) was an ethologist who was (1976–1994) Professor of Behavioural Physiology, Scripps Institute of Oceanography, University of California, San Diego, having joined earlier (1973). [...] (Ref. 128868), visit book page.

Краткое описание определительные ключи | морфология | морфометрия
This species can be distinguished by having the following combination of characters: distinct patch of brown pigment below skin at base of orbit; body yellow and semi-translucent in living specimens; caudal filament long and fine, greater than 20% of LEA (length from the tip of the
snout to the posterior end of the anal-fin base) in intact specimens; electric discharge organ (EOD ) pulse duration very long (between 3.5 and 4 milliseconds at 25° C) with head-positive first phase of longer duration than second head-negative phase in both sexes (Ref. 94132). Body shape (shape guide): elongated.
Facultative air-breathing in the genus (Ref. 126274); Usually found in floating meadow habitats, composed mostly of the grass Paspalum repens, Poaceae. Occurs mainly in white water, but also in areas near the confluence of black water rivers with the Amazonas/Solimões ranging from low to medium conductivity. Syntopic with the species of Eigenmannia, Gymnotus, the apteronotid Parapteronotus hasemani and the electric eel Electrophorus electricus in the floating meadow habitats (Ref. 94132).
