How GBIF deals with uncertain identification notes (nr. prox. probably others).

[jhnwllr]

gbif/portal-feedback#4124

Within entomology, species proxima (Latin: 'the nearest species', abbreviated prox. or sp. prox.) and species near (abbreviated nr. or sp. nr.) indicate a specimen is similar to, but distinct from, a described species.[4]

The GBIF name matcher does not take into account "uncertainty" qualifiers in embedded the name (for example: nr. prox.).

For example,
Camponotus vicinus nr. Mayr, 1870 has a qualifier of "nr." for "near". Meaning the publisher was not sure about it.

All occurrences with this name get a taxon match higherrank flag.
https://www.gbif.org/occurrence/search?advanced=1&verbatim_scientific_name=Camponotus%20vicinus%20nr.%20Mayr,%201870

Because the name parser recognizes it as a subspecies ("rankMarker": "infrasp.")
https://api.gbif.org/v1/parser/name?name=Camponotus%20vicinus%20nr.%20Mayr,%201870

Searches for Camponotus vicinus Mayr, 1870 without "nr." return "nr." occurrences as well.

Here is a table of other nr. examples. All suffer from the same issue of false positive higher rank flagging and no account for the nr. qualifier.
