Abstract
The Catalogue of Life Checklist is an assembly of expert-based global species checklists with the aim to build a comprehensive catalogue of all known species of organisms on Earth. Continuous progress is made towards completion, but for now, it probably includes just over 80% of the world’s known species. The Catalogue of Life estimates 2.3M extant species on the planet recognised by taxonomists at present time. This means that for many groups it continues to be deficient, and users may notice that many species are still missing from the Catalogue.
What’s new in November 2021 edition?
71 checklists have been updated:
- 3i Auchenorrhyncha
- ITIS (incl. new global checklists for families Macronyssidae & Cybocephalidae)
- Scarabs
- ThripsWiki
- World Ferns
- World Plants
- WoRMS, 65 checklists
