Nope, nothing else in the genus Iris. If anyone knows otherwise,
though, send me links to the appropriate info. A lot of states only
prohibit a few agricultural or aquatic weeds; comparatively few ban
invasive ornamentals.
Many non-governmental groups list pseudacorus as invasive, and there
are some control efforts in states where it's not banned, for example
Oklahoma:

(actually I now see that Oklahoma officially lists it as a "species to
watch").
Another interesting thing I came across: Montana actually has a plan
to specifically eradicate pseudacorus. It's considered to not be
widely established, but common where it is. They estimate there are
17,000 acres infested, and have allocated about half a million dollars
towards controlling just this species.

>> Others treat it like an invasive ornamental where it is illegal to

>>
>> In Minnesota it is legal to buy and sell, but is a "regulated
>> invasive" that is illegal to release into the wild.
>>
>> These laws should probably be assumed to include all cultivars,
>> varieties and hybrids, and to ban trades and gifts as well as outright
>> sale. Massachusetts clearly prohibits all of the above, while
>> Connecticut allows hybrids unless specifically banned.
>>
>> Few other irids are currently considered noxious weeds. The US bans
>> Moraea collina, M. flaccida, M. miniata, M. ochroleuca and M. pallida
>> (all formerly Homeria spp.) without a permit. California prohibits
>> Watsonia meriana v. bulbillifera.
