'Platyrhine' is another way to describe primates that have a flat nose with wide nostrils. These primates are New World monkeys that are found in places like South America. Think of it like saying 'broad-nosed'. πIt distinguishes them from Old World monkeys and apes, which have narrower noses. Often, it's used interchangeably with 'platyrrhine'. It's used less frequently these days.
