ok so kip, if i've got this right then the antarctica continent is called kolokia and your peninsula is called kallisto?
protip: the most likely starting point of high technology civilization is in either nausikkak or the loviniosa+ethanthova continent, whatever that one's called, unless it's connected to kallisto in which case kolokia will be the first to develop civilization, and nausikkak would be right behind kolokia. the reason that it's the ethan+lovini continent is because it's huge, same with nausikkak, so the continent has great variety.
btw, ethanthova's terrain will have to be very homogeneous and easy to get through to get such similar culture over such a massive area. the alternate option for this to be possible is for ethanthova to have been colonised from somewhere else.
if naru doesn't mind his nations being highly bilingual, trilingual, or even more, then bielosia, lyintaria, and holy yektonisa are fine. but as it is now, those areas are simply too large to have such a similar culture. the only area on earth where i can think that there's a massive area of similar culture (pre-colonisation) would be most of mid-china, and even then south china and manchuria are vastly different from mid-china.
