The usual trend is to use the concept as described by others above.
Basically its an arbitrary group of species distinguished by a decided gap
from other such groups of species, pretty much straight from Mayr. I was
dissatisfied with that definition hence I had to define it for myself. I
wrote it up as I said above but it was a part of my Masters Thesis, not
actually published in a reviewed journal. Something I regret.
The main reason I had issues with that definition was that there was no way
of being observably consistent in applying it. No way of quantifying what a
genus was. I felt that as we became more determined to really nail what a
species was that it was necessary to do the same with the genus. Since they
are linked and they convey information together, as well as singularly.
So I was basically trying to come up with logical means for demonstrating
that a group was, or was not a genus. I probably should revisit and publish
