Homonyms

IRMNG homonym list - species level - Initial letter = "O" (1242)

Note, this list includes both homonyms between codes (which may be valid in both cases) and homonyms within codes, of which in normal circumstances only one will potentially be a valid combination, according to the priority of the relevant genera.
Note also, that homonymy between species epithets in zoology originally established in different genera (even if the latter are themselves homonyms) is to be disregarded under the ICZN Code, Article 57.8.1.
