While seed propagation has existed since then, Neos were not successfully seed propagated until about the 1980s, so pretty much any neo registered or discovered before the 70s-ish came about without active human intervention. However, that doesn't necessarily mean that they were discovered in the wild. There are quite a few varieties that were discovered as sport mutations as well. There are only about 5 Japanese registered neos that came about through seed propagation by humans.

Dendrobium moniliforme, Asian cymbidiums, even Bulbophyllum japonicum and inconspicuum has a dozen or so varieties....though, while yes, neos do seem particularly mutation prone, I suspect it has to do more with horticultural traditions that so many varieties come about. Japanese horticulture has celebrated bizarre and unusual mutations for the better part of a millennium, and many many plant species have lots of cultivars selected in Japan, Hostas being a big one that comes to mind, along with Rohdea japonica, Rhaphis excelsa...etc.

So I try to find the most cold hardy individuals in each species (not just orchids) I grow.

Neos....the furthest north that Neos can be found in Japan is not much further north than Tokyo, and even then only on the lowest altitudes. Korean native Neos are probably more cold hardy, but they're impossible to find. Pretty much all of the "Korean varieties" are actually bred by Korean breeders from Amami stock which are even less cold hardy.

I can't really say which ones are from the coldest parts of Japan since I don't really know the elevation information of where they were found, but most varieties originally discovered in the mainland of Japan will easily tolerate temperatures down to 40F, with occasional short dips down to 30F. The key though is to make sure that the drop in temperature in the fall is gradual enough for the plants to shift into dormancy mode. You can tell when the plant does because the leaves will gradually become thinner and a little bit wrinkled. Don't give water any time the temperature is below 45 or so, and only a very light watering once a week or so when above that temperature.
Perhaps try this for a year or so with a cheap standard neo (not an Amami), and see how it tolerates the temps.

North Korea is much too cold for any epiphytic orchid. If equated to the USDA zones, North Korea falls in range of zones 4 to 7, and has very harsh winters.
The original description paper for richardsiana does mention Korea but says "Northern Korea" which is rather vague, and the paper seems to imply that as anywhere north of the natural range of falcata on the Korean peninsula which is limited to the very southernmost coast line and islands.
Wild collected neo's?
