DiagnosisAdditional details, e.g. a detailed description or comparisons (3789 characters), are available for collaborators and contributors. Please contact us for details. 
CommentHybridization: Hybrids between Eunectes notaeus and E. murinus have been described and E. deschauenseei is extremely closely related to E. notaeus (fide DIRKSEN & BÖHME 1998).

Phylogenetics: E. notaeus, beniensis, and deschauenseei are closely related and Rivas et al. 2024 suggested to synonymize them, cofirming data by Tarkhnishvili et al. 2022.

Distribution: see map and list of localities in Tarkhnishvili et al. 2022: 380 (Fig. 1). 
EtymologyNamed after Greek notiaios (νωτιαῖος), of the back. (COPE 1862, Esteban Lavilla, pers. comm., April 2024)
