It is possible to a use a noun as an epithet if it is a genitive [Rule 12c (3)] or a nominative in apposition [Rule 12c (2)]. The gender of such epithets does not reflect the gender of the genus name. The species and subspecies names found in LPSN and including epithets that are a nominative in apposition are listed below except for those ending in -cola. Note that some of the epithets listed below could also be interpreted as genitive nouns or even as adjective. See also the LPSN introductory page on forming names.
In the case of a ☞ new combination these epithets must not be adapted to the gender of the genus name.
