Heterotanytarsus Spärck, 1923

We collected five larvae of Heterotanytarsus perennis Saether, 1975 from a first-order tributary to Polk Creek on Prince of Wales Island and eight other unnamed streams and one unnamed lake in Southeast Alaska. We also found larvae in Kucheak Creek west of Atqasuk and six other small unnamed streams on the Arctic Coastal Plain. This is a new faunistic record of the genus for the USA. H. perennis Saether, 1975 was previously only known from British Columbia and Labrador. The larvae of species in this genus inhabit ponds, shorelines of lakes, and slower reaches of streams, where they build cylindrical tubes incorporating substrate particles similar to those of Abiskomyia and Tanytarsini species (Andersen et al. 2013).
