Gymnotus carapo group
Fig. 5A
Distribution.
Upper rio
Parauna
, rio
Sao
Francisco basin, and upper rio Santo
Antonio
, rio Doce basin.
Diagnosis.
Gymnotus carapo
group is diagnosed by having the mouth upturned, pronate; rictus curved ventrally; eyes positioned below half of median line of the head; branchial opening throughout the posterior margin of opercle; oblique and conspicuous dark bands in the lateral of the body, from dorsal region to ventral surface of preanal; longitudinal band reaching the base of the anal fin.
Remarks.
Although
G. carapo
is widespread from Trinidad and Tobago to Argentina, in this study we refer the species as
G. carapo
group, since the taxonomic status of
G. carapo
is uncertain for the Southeastern and Southern Brazil and may represent more than one species. A taxonomic review of the
G. carapo
group in Central and South America is needed.
