     The authors show this species is present in Gunnison County. The following was copied from page 442:
"Drainages: Arkansas, Colorado, Gunnison, North Platte, South Platte.
Habitat: lakes, seeps.
Altitudinal range: 2743 to 3658 meters.
Adult Collection Dates: 10 July to 10 September.
Commentary: Banks reported the type locality as Fort Collins, Colorado. The altitude at Fort Collins (1519m) is inconsistent with that of our lowest collection site (2743m). Therefore we doubt the validity of Fort Collins being the type locality for this species. "

     Abstract: "Western records for 27 species of Trichoptera are given; a majority of the records are from the Beartooth Mountains of northwestern Wyoming. In addition, examples of variation in the male genitilia of Limnephilus coloradensis (Banks) are figured and the female is described. Some comments regarding the larvae of Allomyia (Imania) are presented."
