It appears to me that the data is not duplicated between synonyms is this case.

There appears to be mapping of occurrences between the two names. Nereis virens Sars, 1835 <--> Alitta virens (M.Sars, 1835)

This is the backbone taxonomy record: https://www.gbif.org/species/5196123 However, the original publication information is only contained in the COL-checklist record: https://www.gbif.org/species/174769627 ("This is the interpretation of the species as published in Catalogue of Life Checklist."; links to https://www.gbif.org/species/5196123)

The Alitta virens (M.Sars, 1835) record (https://www.gbif.org/species/2315395) links three synonyms "Nereis virens (M) Sars, 1835":

• Nereis virens Sars, 1835: https://www.gbif.org/species/5196123 (backbone)
• Nereis virens Sars, 1835: https://www.gbif.org/species/10958414 (COL interpretation, no occurences)
• Nereis virens M Sars, 1835: https://www.gbif.org/species/11059131 (World Polychaeta Database, no occurences, wrong original publication "Turnbull, Frederick M.

@ApoSimon should this be reopened?

@jhnwllr I think so, yes. It seems to me to be a case, which probably holds some insights into similar problems of species level taxa matching.
