Phylogenetic hypotheses of interrelationships among Gymnotus species. Results of analysis of morphological data to left; preliminary results from molecular data at right. Note both datasets agree on the division of Gymnotus into three species-groups; Clades C, E, and N. Clade C is endemic to Middle America, whereas Clades E and N are endemic (with one exception) to South America.
