Sentence:  While the Code does not apply to taxa above the family level, Corliss (1962a) argued that it is common sense to apply these principles at the <WSD>suprafamilial</WSD> level, and we have followed this recommendation. When a <WSD>suprafamilial</WSD> taxon has been simply transferred within a higher taxon or between higher taxa, even if it has changed its rank, we have retained the priority date from the original publication along with the original authorship. This promotes stability and recognizes priority. 
Meaning of the word marked with <WSD> tags:  Whose taxonomic level is higher than family.
