Abstract
15 new species from North America are described: I. alaskensis n. sp. (Alaska), I. atkasukiensis n. sp. (Alaska), I. blufusata n. sp. (Holarctic), I. christianseni n. sp. (Illinois), I. creli n. sp. (Alaska), I. inupikella n. sp. (Alaska), I. komarkovae n. sp. (Alaska), I. macleani n. sp. (Alaska), I. manitobae n. sp. (Manitoba), I. maxillosa n. sp. (Illinois), I. nanseni n. sp. (Holarctic), I. nixoni n. sp. (Alabama, Indiana, Kentucky), I. randiella n. sp. (Illinois), I. taigicola n. sp. (Alaska) and I. torildae n. sp. (Illinois). The systematic characters are briefly discussed. In particular the morphology of the antennae, labrum, maxillae, ventral tube and furca were found useful. Cyclomorphosis (occurrence of distinct summer and winter forms) was found in I. blufusata n. sp., I. neglecta Schäffer and probably I. inupikella n. sp. A key for separation of the new species and some related ones is given. All the new species belong to the subgenus Desoria Nicolet, 1841.Keywords
