Bracchidios and Urcusis. The instruction manual at TGS also used Plesioth, which isn't the Japanese name of that monster. Jinouga's name is also written as "Zinogre" in some Japanese merchandise, but that's a valid (if unconventional) transliteration of the name, not a name change.

Bear in mind, Capcom also used "Monster Hunter Freedom 3" in some Japanese recruitment video - that had nothing to do with localization.
