Paratriarius coccineus (Baly, 1865) deleted from backbone

[dartar]

Describe the problem: For reasons that are not explained, Paratriarius coccineus (Baly, 1865) was deleted from the GBIF backbone taxonomy. However, as NHM curator Michael Geiser points out in this thread, the name is valid and there is no reason why it should be deleted.

Unfortunately, CoL has no global checklist provider for subfamily Galerucinae (Chrysomelidae), where genus Paratriarius locates. It's a gap in CoL.

@yroskov thanks for the prompt reply! Does this mean that Paratriarius and children were previously included based on a data provider that has now been deprecated/considered invalid? Trying to understand the mechanics of the deletion of the previous entry. Thanks!

I checked previous CoL editions up to 2005: the genus Paratriarius appeared in the CoL between 2008-2019 (with only one species Paratriarius dorsatus (Say, 1824)) as a part of regional sector of ITIS http://www.catalogueoflife.org/annual-checklist/2008/search_results.php?search_string=Paratriarius&match_whole_words=on

Paratriarius coccineus (Baly, 1865) was never listed in the CoL. Seems, it was taken from another resource into GBIF Backbone Taxonomy.

Interestingly there is no more P. coccineus in any of the GBIF datasets and not any other combination in beetles either: https://www.gbif.org/species/search?offset=20&q=coccineus&highertaxon_key=1470&qField=SCIENTIFIC

It used to be part of the GBIF Type Specimen dataset which we deleted and do not use as a backbone source since early 2021.

In ChecklistBank there is only Open Tree of Life which sourced it from an older GBIF Backbone copy. So we genuinely lack a dataset with the species, not even a regional or thematic one.
