DNA barcoding was applied to select macroinvertebrates from aquatic bioassessment samples collected from National Parks and Preserves in Alaska, USA. The finer taxonomic resolution provided by barcoding revealed the presence of 28 insect species previously unreported from Alaska; 21 of these are also new records for the USA, and 7 are new records for North America, excluding Greenland. The new records are distributed among Diptera: Ceratopogonidae (1), Chironomidae (20), Limoniidae (1), and Tipulidae (1); Ephemeroptera: Baetidae (2); and Trichoptera: Apataniidae (1), Goeridae (1), and Leptoceridae (1).
