felis is a small cats and panthera is a big cats
The answer above is not quite correct. Oddly enough, the characteristic which taxonymists use to make the distinction between these two genii is the roar, or conversely, it's absence. There are only two members of the genus panthera found in the new world, the Lynx(Panthera lynx canadensis) and the Bobcat(Panthera lynx rufus). Although significantly larger than either of it's fellow Western Hemisphere co-habitants, The Puma, or as it is known in some parts, the Mountain Lion (Felis concolor) is endowed with a caterwaul (or 'scream') rather than a roar and is thus a member of Felinaerather than Pantherina.
There is one more genus present in the family felidaepopulated with but a single member. Acinonyx jubata, or more familiarly, the Cheetah is the fastest running of all the felines. (fastest running critter on the whole planet, for that matter..) The cheetah purrs but hasn't a roar. The characteristic which earns jubata it's very own genus is the lack of retractable claws. (I think that if I were tooling along, barefoot, at a brisk clip of 70 m.p.h. or so, I might be tempted to leave my claws out for traction as well!)
I hope that this answers your question clearly and adequately.

Genus Felis includes small cats like domestic cats and bobcats, while genus Panthera includes big cats like lions, tigers, leopards, and jaguars. The main difference lies in their size and morphology, where genus Panthera species are typically larger and more robust than genus Felis species. Additionally, most genus Panthera species can roar, while genus Felis species cannot.
All cats big and small belong to the family Felidae. But of the 37 species of felids, only 8 of them can roar! The other 29 species of cats are meowers. Cats that meow are classed in the subfamily, Felinae.
Felinae are casually called "the small cats" because 27 species are small compared to their big cat relatives the jaguars, lions, leopards, and tigers. But what traditionally distinguishes cat tribes in zoology is not their size. It has more to do with anatomical variations, including those that help cats make the sounds they do.
Whether a cat roars or meows seems to be from a difference in their throat anatomy. Cats that can roar have less densely ossified hyoid bones. This is thought to affect how related throat structures influence sound.
Two big cat species are meowers who cannot roar. These big cat meowers are the cheetahs and pumas, and they are classed with the "little cats" in Felinae. All varieties of domestic cats are Felinae, and there are quite a few wild Felinae species throughout the world. Some are the caracal or desert lynx, the bay cat, the Asian golden cat, the Chinese mountain cat, Pallas's cat, the sand cat, and the black-footed cat. Argentina's Geoffroy's cat is also a small wild Felina, as are the Andean mountain cat, pampas cat, the ocelot, and the margay or tigrillo. The marbled cat of India and Southeast Asia belongs in this subfamily, too, as do the fishing cats, the Indonesian flat-headed cat, the North American bobcat or bay lynx, the other lynxes, and quite a few more, including the fairly large serval.
Felinae are sometimes called, "the true cats." Maybe this is due to the relatively large number of species in this subgroup. Certainly the big cats would object! The Latin adjective felina simply means, of or belonging to a cat.
the diffences is the different feature a pantherea is a large cat with a roar like a lion and a felis is a much smaller cat like pet ones
Jaguars in general are belonging to the cat family wildly, but it belongs to the leopard family.
The tiger belongs to the genus Panthera.
The genus of vertebrates is a taxonomic rank that groups together closely related species. For example, the genus Panthera includes species such as lions, tigers, and leopards.
