''Pseudobarbus'' is a
ray-finned fish genus in the
family Cyprinidae
Cyprinidae is a family of freshwater fish commonly called the carp or minnow family. It includes the carps, the true minnows, and relatives like the barbs and barbels. Cyprinidae is the largest and most diverse fish family and the largest verte ...

is derived from the
Ancient Greek ''pseudes'' ("false") and the
Latin word ''barbus'' ("beard", in reference to the
barbels of
barbs). This genus contains some (and might contain all) of the South African redfins. It was originally proposed as a
subgenus
In biology, a subgenus (plural: subgenera) is a taxonomic rank directly below genus.
In the International Code of Zoological Nomenclature, a subgeneric name can be used independently or included in a species name, in parentheses, placed between t ...
, but has since been found worthy of recognition as a full genus.
This genus is restricted to
southern Africa; all of its species were formerly placed in ''
Barbus'', the genus of typical
barbels and their relatives. One
taxon was originally described as ''P. leonhardi'' – this, however, was a
European fish for which the genus was erroneously proposed anew. It has since turned out to be nothing other than the barbel ''
B. peloponnesius''.
