Etymology: Eigenmannia: From Eigenmann, 1910, researcher of faunistic studies (Ref. 45335); besouro: The specific name besouro ('beetle' in Portuguese) is in honor of Manoel Henrique Pereira, known as Besouro Mangangá '‘The Mangangá Beetle'), a native of the Recôncavo region of Bahia, and a legendary figure in the Afro-Brazilian martial art capoeira. A noun in opposition.
Eponymy: Professor Dr Carl Henry Eigenmann (1863–1927) was a German-born American ichthyologist. [...] Manoel Henrique Pereira (1895–1924) was known by his nickname, Besouro Mangangá (The Mangangá Beetle). He came from the Recôncavo region of Bahia, Brazil (where this knifefish occurs), and was a legendary figure in the Afro-Brazilian martial art capoeira. (Ref. 128868), visit book page.

Estimates based on models
Phylogenetic diversity index (Ref. 82804): PD50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00372 (0.00175 - 0.00789), b=2.97 (2.78 - 3.16), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level (Ref. 69278): 3.1 ±0.4 se; based on size and trophs of closest relatives
Fishing Vulnerability (Ref. 59153): Low vulnerability (10 of 100).
