Allantinae
An allantine for sure, but a tricky specimen. I can't shake the possibility that this is the dark form of Monsoma inferentium (described by Ross in 1932). A clear lateral view of the sawsheath would be helpful: if Monsoma, the top and bottom margins should be subparallel. Otherwise it's probably something else. Either way I'm stumped!
