Leptodoras

Leptodoras is a genus of thorny catfishes native to South America.

Leptodoras is a monophyletic genus based on the single unique characteristic: presence of an infranuchal scute. This scute is the first in a series of well-developed midlateral scutes characteristic of most doradids. It is one of the most derived genera within the clade of fimbriate-barbel doradids. The most closely related genus to Leptodoras is Anduzedoras.
