List of species that are endemic (E), near endemic (NE), have restricted ranges (RR), or occur only locally (LC) in the country. Table also shows species with threatened or endangered status according to the IUCN. Finally, it indicates whether the species is migratory, very rare, or accidental. Names in parentheses (if any) are new official names in the revised Clements updates. '^' indicates range-restricted in country but more widely distributed elsewhere.*
