Dear Kirk,

  some time ago we faced a similar question regarding a new species  
which was similar to Fabricinuda, but not sharing all generic traits.  
Then, we had to decide wether to name a monotypic genus or to redefine  
the existing one and opted for the second choice. This is to say that  
I'm not exactly a splitter. However, in your case I consider more  
appropiate to define a new genus, even if monotypic. The much needed  
revision of the Fabriciinae genera might re-place the taxon oregonica  
or more probably provide new species to be assigned to your genus.


Best wishes

Eduardo
