     The authors split A. severa into three species A. severa, A. elevata and A. thalia. A. severa is restricted to northern North America. Alloperla thalia is present in Colorado and may be the species we have been calling A. severa.

      Quote from page 3: "*thalia Ricker 1952. Syn. severa Hagen. Thalia is the Muse of comedy, but I have forgotten what was amusing here. Hagen's name is evidently from Russian sever = north, the type being from the "Island of Unga, Russian America"."
