Isoperla laucki is shown to be a peculiar member of the genus in western North America based on the male aedeagus, female egg and color pattern of the nymph. Isoperla karuk is included in the Isoperla marmorata complex, where it shares a sclerotized club-shaped process on the male aedeagus. Images of the male and eggs of both species and the female subgenital plate and nymphal mouth parts of I. laucki are provided as scanningelectron micrographs.
