Musteloidea being the superfamily for all four families: Procyonid, Mephitid, Ailurid, and Mustelid. The reason for this proposal is because, though they are of course related from a zoological standpoint, all four families more or less resemble eachother to such an extent that an umbrella tag may be useful for those wanting to search for weaseals, skunks, raccoons, etc. To put this another way: They all kinda just hit the same ¯\_(ツ)_/¯
