Contacyphon ochraceus
This genus was formerly known as Cyphon and many references have this species listed as Cyphon ochraceus.
I think this was the first Contacyphon I identified, and as such I don't have detailed notes as to how I identified it. My photos of the median lobe and 9th sternite don't leave much doubt though. I would have used Mike Hackston's key. It had been beaten from a White Willow tree.
