, and grouped subspecies described, thus shortening the lists considerably. Since the mid-1980s, several ''Panthera'' species became subjects of genetic research, mostly using blood samples of captive individuals. Study results indicate that many of the lion and leopard subspecies are questionable because of insufficient genetic distinction between them. Subsequently, it was proposed to group all African leopard populations to ''P. p. pardus'' and retain eight subspecific names for Asian leopard populations. Based on genetic research, it was suggested to group all living

Contemporary species

The following list of the genus ''Panthera'' is based on the taxonomic assessment in '' Mammal Species of the World'' and reflects the taxonomy revised in 2017 by the Cat Classification Task Force of the Cat Specialist Group:

Extinct species and subspecies

Other, now invalid, species have also been described, such as ''Panthera crassidens'' from South Africa, which was later found to be based on a mixture of leopard and cheetah fossils.
