Baumann,RW, Gaufin,AR and Surdick,RF 1977 The stoneflies (Plecoptera) of the Rocky Mountains. Memoirs of the American Entomological Society 31, 1-208.
     Quoted from page 165: "The family Chloroperlidae in the Rocky Mountains comprises two subfamilies, eight genera and twenty-three species.
Most chloroperlid adults can be distinguished from other stoneflies by their reduced wing veination, oval pronotum and delicate yellow, green or olive drab coloration. The genus Ultaperla, however, is sometimes confused with the genus Capnia by inexperienced students because of its dark coloration. Forking in the second anal vein of the forewing easily separates the chloroperlids from the perlodids.
The nymphs of Chloroperlidae differ from those of other families in Systellognatha by their short cerci, lack of distinct color patterns, rounded wing pads and complete absence of external gills(figs 15, 478). The body is tubular-shaped and bristled; well adapted to burrowing in the fine gravel of streambeds."

Zwick,P 2006 New family characters of larval Plecoptera, with an analysis of the Chloroperlidae: Paraperlinae. Aquatic Insects, 28:13-22.
     Abstract: "Larval structures diagnostic of several Plecoptera families, subfamilies or genera are described and illustrated. They concern the following: distinction of larval Leuctridae from Capniidae; an additional apomorphy of Nemouridae; a synapomorphy of Perlidae and Perlodidae; monophyly of each of the two subfamilies of Chloroperlidae, and the generic limits among Chloroperlidae: Paraperlinae. Paraperla lepnevae Zhiltzova is transferred to Utaperla. Some comments on Notonemouridae are included."
