This is the first of it's family I've seen, collected from a tiny, fishless stream in the Cascades. The three species of this genus all live in the Northwest and are predators that primarily eat stonefly nymphs Merritt R.W., Cummins, K.W., and Berg, M.B. (2019).

It is my understanding that wing maculation is quite distinctive and consistent in this genus thus allowing species identification using this character. This specimen has been at the genus level for many years and somehow slipped through the cracks.;)
