New self-synonymized taxa in Systema Dipterorum

[aoern]

3.334 provisionally accepted taxa in Systema Dipterorum have a self-synonymizing synonym record. All of these taxa seem to be new in Feb 2024 version.

Some examples: Agromyza dimidiata Melander, 1913 Agromyza invaria Walker, 1857 Agromyza varipes Macquart, 1835 Phytomyza chloophila Hering, 1951 Phytomyza diminuta Walker, 1858 Phytomyza solita Walker, 1858 Anthomya gagatea Robineau-Desvoidy, 1830

Thank you, @aoern!

Unfortunately, I do not see these cases through TASK reports. I guess, CLB considers these causes (ACC-SYN species (same accepted, same authors) 1 of 1) as resolved because accepted name is already flagged as "provisionally accepted", and do not include them in the report. It is fine for me. What do you think, @mdoering?

[yroskov]

@proceps & @gdower, what do you think about this, should we eliminate synonym in CoL which is identical to its provisionally accepted name? (We all know taxonomic/nomenclatural background behind these cases).

Original combination/basyonym is also present on the CoL species page:

I don't see any sense in keeping a synonym which is identical to its accepted name. In fact I remove them in the extended catalogue. Is there a reason to keep them?

[proceps]

There is no combination Agromyza dimidiata in TW. This should be an artefact of the data migration from TW to COL.

Looking for duplicates with the same author, rank and accepted name gives me the list: https://www.checklistbank.org/dataset/1101/duplicates?acceptedDifferent=false&authorshipDifferent=false&category=binomial&limit=50&rankDifferent=false

[yroskov]

That report is inconsistent with TASK report on duplicates in Systema Dipterorum INSIDE the project (ACC-SYN species (same accepted, same authors)): https://www.checklistbank.org/catalogue/3/dataset/1101/duplicates?acceptedDifferent=false&authorshipDifferent=false&catalogueKey=3&category=binomial&limit=50&minSize=2&mode=STRICT&offset=0&status=accepted&status=synonym

Yes, CLB it's doing as implemented procedure: it removes square brackets from genus and applies CoL "provisionally accepted" status to the binomial.

I checked few names. Some of them are real (homonymic names), and some have the same issue with the previous one. Additional combination is added during TW to CoL migration.
