Authors of a study published in May 2020 found significant morphological, molecular, geographic, and ecological differences between various Pampas cat populations across South America. They propose five species within the Pampas cat species complex, namely L. colocola, L. braccatus, L. garleppi, L. munoai and L. pajeros.
