The Korean pika as it was first identified by Joel Asaph Allen and Roy Chapman Andrews was independent of any other species,[3] but later treatments referred to it as O. hyperborea coreana, a subspecies of the northern pika.[2] A 2014 review of the molecular biology of Ochotona led to it being considered an independent species once again.[4]
