Cranoglanis
（重定向自Cranoglanididae）
Cranoglanis is the only genus of armorhead catfishes.
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.
