OK, thanks @sea-kangaroo. I use WoRMS too for my marine mollusc work so I can't complain! But it's a bit unsatisfactory given that they are physically distinct from the Atlantic and N Pacific Physalia, and given that P. utriculus is the name used for our local species in the Atlas of Living Australia (which harvests research-grade observations from iNat and may miss them if the name doesn't match). Oh well...
