Names not in the Catalogue of Life under any known name

Source: IUCN Red List 2026-1 vs Catalogue of Life COL26.7 XR (2026-07-17) · 722 rows

The IUCN names below are not in the Catalogue of Life, either as accepted names or as synonyms. A search for similar spellings in the same genus, and with the same species epithet, found nothing. The taxon's other IUCN-listed names are not in CoL either. Taxa where an IUCN synonym is in CoL are on Names not in the Catalogue of Life, but an IUCN synonym is, and taxa where Wikidata or Wikipedia record a name CoL has are on Names not in the Catalogue of Life, but a Wikidata or Wikipedia name is.

Each of these names was also looked up on Wikidata and English Wikipedia. Of the 722 taxa, 353 have a Wikidata item and 149 have an English Wikipedia article. Neither source gives a name for them that is in the Catalogue of Life. The rest have no Wikidata item and no Wikipedia article, so the name is not in use in any source this check covers.

Why it matters

Nothing links these taxa to a Catalogue of Life record. The usual reasons: the name is newer than the CoL release compared against, it comes from a source CoL does not yet cover, or it is spelled differently enough that no match is found.

Suggestion

No change is suggested. The list is for spot-checking against current literature; many entries are legitimately newer than the Catalogue of Life release compared against (its version is given above under Source).

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. Pages are ordered by how likely a row is to need a change.
