Cranoglanis
''Cranoglanis'' is the only genus of armorhead catfishes.
==Taxonomy==
''Cranoglanis bouderius'' was first described as ''Bagrus bouderius'' in 1846 by John Richardson based on a Chinese watercolor painting.〔 Wilhelm Peters later described ''Cranoglanis'' along with a new species, ''Cranoglanis sinensis''. Otto Koller (1926) described a new species, ''Pseudotropichthys multiradiatus''. George Myers (1931) synonymized ''Pseudotropichthys'' with ''Cranoglanis'', as well as described the family Cranoglanididae. Jayaram (1955) synonymized ''C. multiradiatus'' and ''C. sinensis'' under ''C. bouderius''. More recently, ''C. bouderius'' and ''C. multiradiatus'' have been treated as separate species. ''C. henrici'', described by Léon Vaillant in 1893, is often overlooked, but is a valid species.〔
In 2005, ''Cranoglanis'' had been considered a monotypic genus by some, with ''C. bouderius'' as the only valid species.
The Cranoglanididae are closely related to the North American family Ictaluridae. These two families are sister taxa in the superfamily Ictaluroidea.
