I'm a little doubtful that the issue is as resolved as described. You have cited only the ICZN application and subsequent decision. In what publication have North Atlantic Malmgreniella, or other Malmgreniella species, "returned to the genus Malmgrenia"? The ICZN Opinion relates only to the changed type of Malmgrenia, and in the application to ICZN in BZN I could see only your disquiet that Malmgreniella was getting ill-defined.
As far as I know we await a new treatment of Malmgrenia/Malmgreniella. This is necessary subjective taxonomy species by species to assign to genera. Perhaps you or someone else will synonymise Malmgreniella into Malmgrenia, along the way examining all the relevant types, but it hasn't happened yet has it? As far as I know Malmgreniella variegata as used by Rolando remains the valid name to use until someone publishes on it .

Nice paper! However, this seems like a good place to remind readers that the genus Malmgreniella is now known only for one species from the Antarctic (ICZN, 2009). The North Atlantic species have returned to the genus Malmgrenia (for reasons explained in Muir & Chambers, 2008).
