Names with a close Catalogue of Life match

Source: IUCN Red List 2026-1 vs Catalogue of Life COL26.7 XR (2026-07-17) · 799 rows

The IUCN names below appear nowhere in the Catalogue of Life, neither as accepted names nor as synonyms. Each is paired with the most similar CoL spelling in the same genus or with the same species epithet. The Detail column says how the two spellings differ (punctuation, diacritics, Unicode encoding, or a small spelling change).

Two checks run on each suggested match, shown as columns: whether CoL treats it as an accepted name or as a synonym, and whether IUCN already lists it as a synonym of the taxon. Rows where IUCN already lists the close CoL spelling as a synonym of the same taxon are on Name pairs where IUCN and the Catalogue of Life differ on which name is accepted instead.

Why it matters

A name spelled slightly differently in the two catalogues will not cross reference, even when both records describe the same taxon. Automated matching fails and manual searches come up empty.

Suggestion

If the two spellings are variants of one name, record the CoL spelling as an IUCN synonym, or correct the spelling, so the two catalogues link. If CoL treats its spelling as a synonym, compare against the CoL accepted name instead. If IUCN already lists the CoL spelling as a synonym of a different taxon, the two names may be unrelated and the match a coincidence.

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.
