''Bunocephalus'' is a genus of banjo catfishes from South America. It is found in Magdalena, Orinoco, Amazon, Paraguay-Paraná, and São Francisco Rivers. It is also the only aspredinid genus found west of the Andes, found in the Atrato, San Juan, and Patía Rivers.〔 This genus is a part of the family Aspredinidae, known as banjo catfishes for their large, flattened heads and slender tails that give the appearance of a banjo. Most species exhibit cryptic coloration, and the same holds true among ''Bunocephalus'' species. The skin is completely keratinized and is covered by large, unculiferous tubercles.〔 ''Bunocephalus'' species may reach up to 13 centimetres SL.〔 ==Species== There are currently 12 recognized species in this genus: * ''Bunocephalus aleuropsis'' Cope, 1870 * ''Bunocephalus amaurus'' C. H. Eigenmann, 1912 (Camouflaged catfish) * ''Bunocephalus chamaizelus'' C. H. Eigenmann, 1912 * ''Bunocephalus colombianus'' C. H. Eigenmann, 1912 * ''Bunocephalus coracoideus'' (Cope, 1874) (Guitarrita) * ''Bunocephalus doriae'' Boulenger, 1902 * ''Bunocephalus erondinae'' A. R. Cardoso, 2010 * ''Bunocephalus hartti'' T. P. Carvalho, A. R. Cardoso, Friel & R. E. dos Reis, 2015 〔Carvalho, T.P., Cardoso, A.R., Friel, J.P. & Reis, R.E.

''Neotropical Ichthyology, 13 (3): 499-512.''〕 * ''Bunocephalus knerii'' Steindachner, 1882 (Ecuador banjo catfish) * ''Bunocephalus larai'' R. Ihering (pt), 1930 * ''Bunocephalus minerim'' T. P. Carvalho, A. R. Cardoso, Friel & R. E. dos Reis, 2015 〔 * ''Bunocephalus verrucosus'' (Walbaum, 1792) (Gnarled catfish) The removal of ''Pseudobunocephalus'' from ''Bunocephalus'' was an attempt to make it monophyletic. Even in this reduced state, ''Bunocephalus'' is still the largest genus in the Aspredinidae.〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Bunocephalus」の詳細全文を読む スポンサード リンク
