I tried to look at it on ALA for its status without much success it said the name was unranked. I don't know what that meant and it threw me to a general Catocalini page https://bie.ala.org.au/species/https://biodiversity.org.au/afd/taxa/1c1032a2-10f0-4744-85b4-e71d3659795c#classification I am unclear what name to use. Do we add Rapana in a bracket to the above?
I generally infer that when the AFD describes a species as 'Unplaced X';, provides an entry and gives a history for 'Unplaced X' or calls it a 'Synonym of Y', as in this case we shoulddescribe it as Unplaced X on NatureMapr. A while back we decided not to enter synomyms for moths (as recognised by the AFD) to avoid confusion The Australian Faunal Directory (AFD) describes it as 'Species Unplaced trigramma (Turner, 1906)' and says Rapana trigramma as a synonym.
