Tydemania is not an algea #4801

Dear GBIF,

I downloaded all occurrence records for the fish family “Triacanthodidae”, the Spikefishes.

There is a genus of spikefish, Tydemania, that is monotypic as currently understood and the only valid species is Tydemania navigatoris. I noticed that there was another species included in the dataset, Tydemania expeditionis. Tydemania expeditionis is a green algae, not a spikefish. Can GBIF resolve the higher classifications issue (i.e., changing from Animalia to Plantae) or does each institution that has records under Animalia need to update them?

The backbone has both genera and only a single species in the animal one, so this seems correct: https://www.gbif.org/species/2408085

There is another fish name Tydemania japonica Kamohara, 1941, but it is treated as a synonym of Atrophacanthus japonicus (Kamohara, 1941) according to FishBase.

The problems that you have seem to be incorrectly matched occurrences, not a wrong taxonomy. The occurrences of the fish genus indeed contain herbarium records from Australis like this one: https://www.gbif.org/occurrence/1936753016

Most seem to be the algae species Tydemania expeditionis which is in the backbone. But the original taxonomy given by the publisher is just very wrong and makes it a fish :(
