Taxonomy

''Catagonus'' is notable in that the type species, '' C. metropolitanus'', is extinct; the living Chacoan peccary was first described in 1930 from subfossil remains, and only found alive by scientists in 1972 (an example of a Lazarus taxon). A 2017 study on the phylogenetic systematics of Tayassuidae species suggests that ''Catagonus'' should only contain ''C. metropolitanus''. The extinct

narrow-headed peccary ''Catagonus stenocephalus'' (or ''Brasiliochoerus stenocephalus'') is an extinct species of peccary that lived in South America during the Late Pleistocene. Fossils have been found in Brazil, Argentina and Bolivia. It is commonly known as the narr ...

''(C. stenocephalus)'' should be moved into ''Brasiliochoerus'', while the Chacoan peccary, ''C. bonaerensis'' and ''C. carlesi'' should be placed in ''Parachoerus''. If this is accepted, then ''Catagonus'' becomes an extinct genus once more.
