Etymology: Eigenmannia: From Eigenmann, 1910, researcher of faunistic studies (Ref. 45335); guairaca: The epithet ‘guairaca’ is a reference to the legendary Guairacá, a brave Indian chief who was protector of the lands and the Guarani people (Ref. 115689).
Eponymy: Professor Dr Carl Henry Eigenmann (1863–1927) was a German-born American ichthyologist. [...] Guairacá was a semi-legendary chief of the Guaraní people, who sought to protect their land from European colonisers. (Ref. 128868), visit book page.

臀鰭軟條: 151 - 170. Diagnosis: Eigenmannia guairaca can be distinguished from other species in the E. trilineata species group, except E. desantanai, E. microstoma, and E. muirapinima, by the ii,11–12 pectoral-fin rays (versus ii,13–14 in E. antonioi and E. pavulagem; ii,16–17 in E. matintapereira; ii,14–15 in E. trilineata; ii,15–17 in E. vicentespelaea; and ii,13–15 in E. waiwai); Eigenmannia guairaca differs from E. desantanai, E. microstoma, and E. muirapinima by the number of total anal-fin rays, 151–170 (versus 170–198 in E. desantanai and E. muirapinima; and 173–207 in E. microstoma); Eigenmannia guairaca can be further distinguished from E. desantanai and E. muirapinima by the 5 or 6 endopterygoid teeth (versus 14–15 in E. desantanai and 8 or 9 in E. muirapinima); Eigenmannia guairaca differs from E. desantanai by the dentition pattern of the premaxilla with 9 or 10 teeth distributed in 2 rows (outermost row with 4 teeth, innermost row with 5 or 6 teeth) [versus 21–23 teeth distributed in 2 rows (outermost row with 10 to 12 teeth; innermost row with 9 to 13 teeth)]; Eigenmannia guairaca can be further distinguished from E. microstoma by the suborbital depth, 22.2–27.5% HL (versus 29.9–40.8%); the length of anterodorsal process of the maxilla equal to 50% of the width of posterior nostril (versus equal to the width of the posterior nostril); and the length of the coronomeckelian bone equal to 20% of the length of Meckel’s cartilage (versus 45% of the length of Meckel’s cartilage); Eigenmannia guairaca can be further distinguished from all species in the E. trilineata species group, except E. microstoma and E. pavulagem, by 15 precaudal vertebrae (versus 13 or 14 in E. antonioi, E. muirapinima and E. vicentespelaea; 11 or 12 in E. desantanai; 13 in E. matintapereira and E. trilineata; and 12 or 13 in E. waiwai) (Ref. 115689).
