Leptodoras
''Leptodoras'' is a genus of thorny catfishes native to South America. ==Taxonomy== ''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''.〔 This genus includes eleven species, making it the largest doradid genus.〔 There has been taxonomic confusion due to similarities of some species with each other and members of other genera. Misunderstood distributions and identities of some species added to this confusion. Most species were described from small geographic areas without information on their potential distributions. Also, specimens have been rare in museums until recently. An assessment in 2005 diagnosed ''Leptodoras'' and its seven species while describing three new species.〔
