I decided that old map wasn't good enough, so I've started making my own. The white spots are ones where there isn't enough information, either because I haven't gotten around to it, or because I couldn't find any information. Even so, the areas that are colored aren't necessarily complete. Finding criminal laws is much easier than finding marriage prohibitions. For example, I would expect all former Soviet republics to have similar laws to Russia, but I don't know where such marriage restrictions would be written, so I can't definitively say if they allow avuncular marriage. If anyone has some extra info, or wants to correct something I've put on the map, feel free to send me a message. I'd appreciate it.
As an aside, choosing how to designate some of these countries is a bit difficult. For example, no country which enshrines shariah explicitly forbids consanguinamory. However, strict strict shariah dictates that you can't marry a close relative, and sex outside of marriage is punishable, possibly by death. That means in practice it's very illegal. I chose to mark those countries gray, for that reason, even though there's technically no law. Some places are also very complicated, such as Indonesia. Indonesia is a very large and diverse federal nation, so laws can change from place to place. However, national law does not criminalize consanguinamory, as far as I could find, and the only place to implement sweeping shariah law is Aceh province, so I chose to mark all of Indonesia light blue, except for Aceh. This is the reason why it's still important to contact a lawyer who knows your local laws. This map is only a general guide, based on my personal research.
