It was previously classified within Electrophorus electricus when that species was considered the only one in the genus Electrophorus, but a 2019 analysis described it and E. voltai as distinct species based on both their deep genetic divergences and differences in the voltage produced by each species. It is also thought to be the most basal member of the three Electrophorus species, diverging during the late Miocene. It is named in honor of American ichthyologist Richard Peter Vari.[2]
It is found throughout the lowland habitats of the Amazon Basin and in some streams in the Guiana Shield, in contrast to the other two species in the genus, which are adapted to only upland shield habitats.[2] It inhabits turbid rivers with little oxygen and sandy or muddy bottoms.[3][4]
This species closely resembles E. electricus, but lacks the clear band along the body that is usually present in E. electricus. This species produces the second-highest maximum voltage of the three Electrophorus species, at about 572 volts.[2]
