Alexander,KD; Stewart,KW 1999 Revision of Genus Suwallia Ricker (Plecoptera: Chloroperlidae). Transactions of American Entomological Society 125 3, 185-250. This paper describes Suwallia starki (found in our area) among several other new Suwallia species. They study species from North America, Japan and Russia making this an interesting and broader treatment of the genus. This brings the total of Suwallia species up to 23. They include scanning electron microscope images of male genetalia, epiproct, and egg with drawings of the sclerotized rod of aedeagus, female subgenital plate and adult color patterns. Baumann,RW; Gaufin,AR; Surdick,RF 1977 The stoneflies (Plecoptera) of the Rocky Mountains. Memoirs of the American Entomological Society 31, 1-208. Quote from page 171: "Males of the genus Suwallia are characterized by a slender, curved finger-like process projecting inward near the base of each cercus (fig. 487). The epiproct is membranous, with a small hairy, lightly chitinized tip (fig. 488)." Don't use this key for species identifications anymore, there are many more species than the three common ones they discuss! Use Alexander and Stewart 1999 instead Ricker, W.E. 1943.
