The gender of names above the rank of genus, up to and including the rank of class, is fixed by the ☞ ICNP. The gender of each of such names is given on its respective LPSN page.
As a rule, names above the rank of genus are formed by appending a category-specific suffix to the ☞ stem of the name of a genus. The LPSN glossary contains information on how names of ☞ classes, ☞ families, ☞ orders, ☞ phyla, ☞ subclasses, ☞ subfamilies, ☞ suborders, ☞ subtribes and ☞ tribes are formed.
Many validly published names of classes deviate from the expected scheme, hence a separate overview is provided.
The grammatical gender of names of ☞ genera (and ☞ subgenera) can be masculine, feminine or neuter. The grammatical gender of virtually all validly published names of genera is given on their respective LPSN page.
As an aid for the formation of new genus names, LPSN includes special pages that list the names of genera assorted by their grammar and gender.
The grammatical gender of names of ☞ species and ☞ subspecies is determined by the gender of their genus name and can accordingly be masculine, feminine or neuter. The grammatical gender of virtually all validly published names of species and subspecies is given on their respective LPSN page. If the epithet is an adjective, it must be adapted to the gender of the genus name.
As an aid for the formation of new names of species and subspecies, LPSN includes special pages that list the names of species or subspecies assorted by their grammar and gender.
The ancient LPSN page on three-letter codes for abbreviations of generic names is not going to be moved to the new system. Please see the archived version. The current LPSN authors opine that the usage of these abbreviations should be discontinued because they are not needed any more to save printing space. In fact, most journals (and readers) are switching from print publications to electronic publications.
The ancient LPSN pages on the etymology of genus and species names are not going to be moved as such to the new system. Please use the general search page instead for searching for name components, consult the up-to-date etymological arrangements of names listed above, or see the archived versions of the ancient pages:
