|This species is extinct; its fossils have been found in the [[La Venta (Colombia)|La Venta fauna]] ([[Miocene]]) in Colombia. Its validity, however, is questionable.

Rivas ''et al''.<ref name="rivas" /> revised the taxonomy of ''Eunectes'', describing a new species of green anaconda (''Eunectes akayima'') and merging ''E. deschauenseei'' and ''E. beniensis'' with ''E. notaeus'', which resulted in the recognition of only three species of anaconda. The result of their phylogenetic analysis is represented below:
{{Clade
|label1=Green anacondas
|1={{clade
   |1=''[[Eunectes murinus]]''
   |2=''[[Eunectes akayima]]'' }}
|label2=''[[Eunectes notaeus]]''

   |1=''Eunectes notaeus''

            |2="''[[Eunectes deschauenseei]]''"
}} }} }} }} }}
In a response paper, Dubois ''et al''. questioned the results of the [[Mitochondrial DNA|mtDNA]] analysis above and the validity of ''Eunectes akayima''. The name of the new species was considered a ''[[nomen nudum]]''.<ref>{{Cite journal |last1=Dubois |first1=Alain |last2=Denzer |first2=Wolfgang |last3=Entiauspe-Neto |first3=Omar M. |last4=Frétey |first4=Thierry |last5=Ohler |first5=Annemarie |last6=Bauer |first6=Aaron M. |last7=Pyron |first7=R.
