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.
