^ Actually, MH4 is believed to be inbetween the Old and New World and, Shinato Village and the Heavenly Mountains are suppose to be in the Siki Country, an area in the Old World, and they also get all those materials of monsters from other regions like the Loc Lac and Jumbo. Also afew of these monsters were just recently discovered in Barubare's Region like Zinogre, the Kirin Subspecies, and Goa Magara while most of the newer monsters are well known in that region. Another thing to note is afew of these monsters could be considered subspecies of their own independent region from their behavior and afew other things being different with them like the Raths of Barubare's Region are believed to be a bit more vibrant than the ones of Moga's Region and also seemingly alot smarter.
