code of nomenclature question

[Karin Kiontke]

Hi everybody,

I have a couple of questions regarding nomenclature rules (I don't
have the latest version of the code at hand):
1. When transferring a species from a genus to a subgenus, am I still
supposed to adjust the species epithet according to the gender of the
genus? Someone told me that this isn't done anymore.
2. I want to talk about groups of species inside of a genus but
without creating subgenera. I am using currently terms like "Elegans
group of Caenorhabditis". Do any of the rules apply to such names
with regard to capitalizing and italicizing?

Thanks,

Karin
