Key characters
"Female cercus elongate-cylindrical, sparsely covered with long uniform setae" ... Calamomyia

"Female cercus, if elongate-cylindrical, with setae either short or of varying length" ... some other Alycaulini, probably Chilophaga

Help.
I didn't know these had cercus. When I look where I think they might/should be, I don't see anything.

Cerci
They are at the tip of the ovipositor. You probably can't see them with your camera.
