Pseudoepameibaphis Gillette & Palmer
This is a genus that I have collected avidly for many years. It is a specialist on sagebrush, with peculiarly shaped siphunculi.
Four species are currently recognized, although based on the full range of specimens in my collection, I cannot confidently say I agree with that notion, nor identify my specimens based on the published keys and comparison to types. As is often the case, the keys are based on characters that seem far too variable to be reliable, which in my opinion requires development of entirely different diagnostic characters. I might be close to figuring out the genus, but now that I live in a new and unusual habitat I plan on another couple years of research before writing up my conclusions.
