كليدهاي شناسايي | ريخت شناسي | ريخت ستجي بوسيله انداره گيري
Brachyhypopomus menezesi is distinguished from other species of the genus Brachyhypopomus by the following combination of characters: presence of accessory electric organ over the opercular region (vs. absence in all congeners except B. bombilla and B. regani); dorsal surface with large dark blotches against a lighter background (vs. dorsal surface speckled with small brown chromatophores on a pale background in B. bombilla); and caudal filament length 24.7-33.3% of length to end of anal fin (vs. 11.1-17.9% in B. regain) (Ref. 116763).
Facultative air-breathing in the genus (Ref. 126274); Occurs in small rivers, streams, and lakes based on geographical coordinates and labels accompanying the examined museum specimens. Stomach contents of a single specimen consisted of aquatic insect larvae, mostly Chironomidae (Ref. 116763).
