Hm, I am inclined to think it is a Saltrichocera of sorts and especially with this dark colouration and long cerci - check Trichocera saltator, for example. This said, I haven't had verified females from hiemalis, only a handful of males, and these all were a bit more reddish on the cephalothorax.

Maybe views of the antennae, of the tarsal claws etc. could be of help.
