Name pairs where IUCN and the Catalogue of Life differ on which name is accepted
Source: IUCN Red List 2026-1 vs Catalogue of Life COL26.7 XR (2026-07-17) · 2,742 rows
IUCN and the Catalogue of Life accept different names for each taxon on this page, and the IUCN record already lists the name CoL accepts among its synonyms. Some rows are mutual: CoL likewise treats the IUCN name as a synonym of its accepted name. In the others the name IUCN accepts appears nowhere in CoL, and the pairing rests on the IUCN synonym list alone. Either way the two records can be cross referenced, so nothing on this page is a missing name or a broken link.
Why it matters
Not much is at stake: nothing on either side is wrong, and nothing here needs fixing. Two details are still worth knowing. The link between the pairs lives in the IUCN synonym list, which is published through the Red List API but not in the CSV export, so a match run against the export alone misses it. And a small number of rows give the same author two different publication years, one per catalogue; that can be a real bibliographic difference, as with a work issued in parts, or a transcription error, and those rows sort to the top of the table.
Suggestion
No change is suggested. The table works as a concordance between the two datasets, as the list of taxa that would change name if the Catalogue of Life treatment were adopted, and, where the Authority years column is filled, as a short checklist of publication dates the two catalogues disagree on.
The Catalogue of Life crosscheck
Every assessed name is checked against the Catalogue of Life; each difference found is listed on exactly one of the pages below.
| Page | Names | What it lists |
|---|---|---|
| Names not found in the Catalogue of Life | 745 | The name is absent from CoL: no near spelling, and no other name for the taxon either. |
| Names with a close Catalogue of Life match | 799 | The name is absent from CoL; a near spelling exists in the same genus or epithet. |
| Names absent from the Catalogue of Life where another name for the taxon is present | 134 | The name is absent from CoL; another IUCN-listed name for the taxon is there as a synonym. |
| Species and subspecies treated as synonyms in the Catalogue of Life | 11,664 | CoL treats the name as a synonym of an accepted name IUCN does not list. |
| Higher-rank names treated as synonyms in the Catalogue of Life | 717 | A genus or higher name CoL records only as a synonym. |
| Higher-rank placement differences that look like spelling variants | 94 | A higher taxon whose CoL parent name looks like a spelling variant of IUCN's. |
| Minor naming authority differences | 9,343 | Exact name match; the author is spelled differently. |
| Name pairs where IUCN and the Catalogue of Life differ on which name is accepted this page | 2,742 | Both catalogues hold both names and disagree only on which is accepted. |
| Higher-rank names placed differently in the Catalogue of Life | 1,663 | A higher taxon placed under a genuinely different CoL parent. |
