I. 4. Family Chloroperlidae

Subfamily Chloroperlinae

The generic statuses of the family was reviewed on the Nearctic genera by Surdick (1985).

Genus Alloperla Banks, 1906

The species 2-5 are closely similar though they show different coloration. Though their enlarged epiproct disagree with the other Alloperla, they have undivided female subgenital plate as normal Alloperla.
