Quote from page 571: "A few western Nearctic limnephilids were recorded infrequently or have not been observed in recent years based on the material we examined. Limnephilus productus Banks, 1914, was collected in 1995 near Shadow Mountain Dam in Grand County."

     The authors realized Limnephilus utahensis by Denning 1948 was a synonym. Quote from page 454: "To date this species is kown only from Utah. There appears to be extremely little variation in the species, judging from examination of Banks' type, additional material from Utah and Dennings's illustrations. "
