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 Bestämningsnycklar | Morfologi | Morfometri

Mjukstrålar i analfenan: 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).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = No PD50 data [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).

Trofisk nivå (Ref. 69278): 3.1 ±0.4 se; based on size and trophs of closest relatives

Fishing Vulnerability (Ref. 59153): Low vulnerability (10 of 100).
