There was a proposal to divide the Pampas cat into three distinct species, based primarily on differences in pelage colour/pattern and cranial measurements.[3] Accordingly, three species were recognised in the 2005 edition of Mammal Species of the World: the colocolo (L. colocolo), the Pantanal cat (L. braccatus), and the Pampas cat (L. pajeros) with a more restricted definition.[4] This split at species level was not supported by subsequent phylogeographic analysis, although some geographical substructure was recognised,[5][6] and some authorities continue to recognise the Pampas cat as a single species.[2][7] In the 2017 revision of felid taxonomy by the Cat Specialist Group, the Pampas cat is recognized as a single species with seven subspecies.[1] An analysis of 142 skins collected across South America revealed morphological differences between these museum specimens. It was therefore proposed to recognize five distinct species within the Pampas cat complex.[8]
