TaxonNamePopEditor: name part field visibility not correct for all ranks
I checked the complete list. With some ranks (mostly not relevant for PhycoBank, I have problems).
"species aggegate" should also have an additional uninominal (to link it to a given genus).
"species group" should also have an additional uninominal (to link it to a given genus).
"candidate" is not relevant to PhycoBank, but I would expect that 99-100% of candidates in bacteriology will be a species -> delete "infraspecific epithet" there.
"unknown rank": I would suggest to offer just a "uninominal" because if there are genus and one epithet it should be a species, if it is unknown infraspecific, we have an own entry.
