Diplomystes is a genus of freshwater ray-finned fishes belonging to the monotypic family Diplomystidae, the velvet catfishes. These are basal catfishes endemic to freshwater habitats in Argentina and Chile in southern South America.
==Taxonomy== The family Diplomystidae has been considered as the basal, primitive sister group to all other catfishes (Siluroidei) on the basis of morphological evidence. Almost all molecular estimates of catfish phylogeny, by contrast, find Diplomystidae sister to Siluroidei, with Loricarioidei (the armoured catfish and relatives) the most basal group; though this may be an artifact of rapid evolution in loricarioids.
