Etymology: Eigenmannia: From Eigenmann, 1910, researcher of faunistic studies (Ref. 45335); sayona: Named in reference to 'La Sayona', a spirit of philanderous veneance in Venezuelan lore (Ref. 128865).
Eponymy: Professor Dr Carl Henry Eigenmann (1863–1927) was a German-born American ichthyologist. [...] In Venezuelan folklore, La Sayona is a spirit of philanderous vengeance. Apparently, the name is a homage to the Venezuelan people with no meaning or significance to the fish itself. (Ref. 128868), visit book page.

Short description Claves de identificación | Morfología | Morfometría

Radios blandos anales: 198 - 217. This species is distinguished from its congeners by the following set of characters: presence of a superior midlateral stripe; an ossified first basibranchial; A 198-217 fin rays; suborbital depth, 21.3-26.1% HL; length of anterodorsal process of maxilla equal to the width of the posterior nostril; distinct dentition pattern of the premaxilla with 17 teeth distributed in three rows; hyaline pectoral and anal fins; and 9-10 scale series above lateral line (Ref. 128865).
