I wanted to ask for opinions on a basic nomenclatural/systematics 
decision that I have to make. I'm finishing descriptions of recently 
collected individuals of /Fabricia oregonica/ Banse, 1956. The original 
material is in extremely poor condition, which precluded me from earlier 
adding to Banse's description. Plus, the only well described species in 
/Fabricia/ up to this point is /F. stellaris/. With these new specimens 
belonging to /F. oregonica/, I've looked at phylogenetic relationships, 
and /F. oregonica/ is not a sister taxon to /F. stellaris/.

So, I have two choices. (1) Place /F. oregonica/ in a yet another new, 
monotypic genus. (2) Leave the species in /Fabricia/, and just 
acknowledge that the genus can't be unambiguously defined.

Any thoughts? Opinions?
