For me things are not that straightforward, comparing new species with endemics. A newly described species over a period of time may be discovered in neighbouring areas also, or merged with already known species from surrounding areas, it is only that author first describes it from a particular region. An endemic on the other hand may have arisen recently (through mutations, or crossing followed by duplication of chromosomes, since hybrids of most diploid species are sterile and perish very soon, unless maintained by vegetative means) and did not get get enough time to spread to similar surrounding areas (neoendemics), or widely spread once but getting restricted due to shrinking of their habitats (Palaeoendemics).
