Brandtia parasitica, which traditionally has been considered a parasite of Lubomirskiid sponges (gut analyses have shown that it is not), was formerly placed in Brandtia, but it has been moved to Dorogostaiskia.{{cite WoRMS |author=Väinölä, R. |author2=Daneliya, M. |author3=Lowry, J. |year=2015 |title=Dorogostaiskia Kamaltynov, 2002 |db=Amphipoda |id=244493 |access-date=22 June 2015}} Other species formerly placed in Brandtia have been moved to Gmelinoides (G. fasciatus and G. fasciatoides).
