Epithets of species or subspecies can be formed from latinized personal names in the adjective form or in the genitive noun form. Epithets of species or subspecies can be formed from geographic locations using the endings -ensis (feminine or masculine) or -ense (neuter). However, localities can also have classical Greek, classical Latin or medieval Latin adjectives such as africanus. Epithets can also be nouns. The species and subspecies names found in LPSN whose epithets are unambiguously derived from an entity, but neither derived in the genitive noun form from a personal name nor derived from a location using -ensis or -ense, are listed below, arranged by the name of the entity to which they are referring. See also the LPSN introductory page on forming names.
