No species are known to be strictly endemic to the Republic of Guinea.
Note that using the country border as the endemism criterion creates this result. Political lines rarely match ecological boundaries. Many plants and animals in Guinea occur across the Upper Guinea forest or the Guinea Highlands. Those species are endemic to the region, not to the Republic of Guinea alone. Use IUCN, GBIF, and BirdLife records to check range maps and you will see most so‑called “Guinea” species have ranges that cross into Liberia, Sierra Leone, Côte d’Ivoire, or Guinea‑Bissau.
Expect technical and historical reasons behind the empty national list. Scientists describe endemism by habitat, mountain block, island, or ecoregion more often than by country. Taxonomy also changes: species get split or lumped, and old locality records get revised. Many narrow‑range species occur on cross‑border massifs such as Mount Nimba or in the Upper Guinea biodiversity hotspot. These are near matches — species restricted to Mount Nimba or to the Upper Guinean forests — but they are not confined to the Republic of Guinea alone. Invertebrates and many plants may still be undescribed or poorly surveyed, so true country‑only endemics could be discovered later.
Explore related, useful lists instead. Look for “Endemic species of the Upper Guinea forest,” “Mount Nimba endemics,” and “Fouta Djallon highlands species.” Check regional checklists and databases (IUCN Red List, GBIF, BirdLife) for range, status, and habitat. Proceed by focusing on regional endemics and conservation priorities rather than a strict national‑only list.
