ansorgii is not brand new and not extinct. just that for a very long time no live specimens have been seen, at least in the hobby and the scientific community (now it's harder to tell whether it's just that no one has tried to export them, even though the locals might have known about and seen them). anyway, a while ago the japaneses made the effort to try to find it and were successful, although the quantity is still very small. i saw the first pic of it about 7 months ago. and a month or two ago toyin was able to bring in one specimen.
regarding izzy, it might be a volta variant, which has faded stripes. Or it could be the black substrate, which tends to darken the base color and lessen the contrast, and sometimes give them a charcoal look lol
