Not exactly. The Sharlayans were part of the Eorzean alliance till they left it recently, and they're descendants of Eorzean colonists that were brought over to the island by Nyunkrepf Nyunkrepfsyn 1,500 years ago. The term was first created in Ul-dah as a socio-political term to persecute those they despised(amaljaa among others). The term is never used in Norvrandt for example(the First), or in the case with Lupins who are not considered as such by the locals except by the Garleans. The Hrothgar for example look just as beastly as the Lupin, but they're not considered as beasts for obvious political reasons which the latter story of FFXIV began to show that the people of Eorzea began to change their attitudes of them. Even this guy that written this wish to throw this term as useless.

The term is also used in the continent of Ilsabard as well. It doesn't diminish the idea that these terms were created by the Ulda'ans which spread all over the continent which the Garleans took that as well. The differences in physiology is apparent, but then again, so do the beastmen with each other as well. It's basically a continuum really rather than stricly this or that. Hyur look the most human obviously with the rest going in a direction from human looking to beast looking. In other words, the fact that these terms are not used in the Far East(except for Garleans and etc), or not at all in the First speaks volumes.
