     Google claims I. longiseta is discussed in this paper, but I haven't read it yet.

     Quote from page 141: "The I. quinquepunctata species group (I. acula Jewett 1962, I. jewetti Szczytko and Stewart 1976, I. longiseta Banks 1906b, I. mormona, I. quinquepunctata) is either paraphyletic or polyphyletic (ambiguous). Specifically, I. acula and I. mormona may be more closely related to the other Isoperla included in this study than to I. quinquepunctata. This is consistent with the morphological observations that I. acula and I. mormona share similar aedeagal characters lacking in I. quinquepunctata (Table 1). For both I. acula and I. mormona, the apical half of the aedeagus is conical and ventrally curved with constricted tip and distinct but fine setae are present. If possible additional molecular studies of the two other species of the species group, I. longiseta and I. jewetti (but presumed extinct), should be conducted. It is likely that the species group as it is currently defined will be reconstituted as two or more groups as more information is gathered."

     Quote from page 396: "Isoperla longiseta is known from western and midwestern North America, and occurs further east than any other typically western Isoperla (Szczytko and Stewart 1979). It is often considered a typical praire stonefly of larger streams and rivers. In Colorado it is restricted to the large West Slope rivers, and is especially abundant in the lower Green and Yampa rivers."

     The authors note that A. banksi was one of the most infrequently recorded species out of the 100 different stonefly taxa they collected in their survey of Glacier National park and the Flathead basin in northwestern Montana.
