Doradidae
The Doradidae are a family of catfishes also known as thorny catfishes, raphael catfishes or talking catfishes. These fish are native to South America, primarily the Amazon basin and the Guianas. Doradids are omnivorous. Taxonomy As of 2007, 31 genera and 78 species are in this family. '' Wertheimeria'' is considered to be the sister taxon to all other doradids. This family is monophyletic and contains the subfamilies Doradinae, Astrodoradinae and Wertheimerinae. The Astrodoradinae contain the genera '' Amblydoras'', '' Anadoras'', '' Astrodoras'', '' Hypodoras'', ''Merodoras'', ''Physopyxis'', and '' Scorpiodoras''. Distribution Doradids occur in most South American basins, though they are absent from the Pacific Coast drainages and from coastal drainages south of the Río de la Plata. About 70% of the valid species occur in the Amazon basin; the Orinoco basin harbors about 22 species and ranks second in species richness. Conversely, only two species of doradids have been des ...

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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
