Cladotanytarsus Kieffer, 1921

Watson et al. (1966) collected Cladotanytarsus viridiventris ( Malloch, 1915) adults from the Cape Thompson area. Bowser (2019) used DNA barcoded materials to document an unknown Cladotanytarsus species from the Kenai Peninsula, which he labeled sp. TE04. Bowser et al. (2020) collected Cladotanytarsus nigrovittatus (Goetghebuer, 1922) larvae as Cladotanytarsus mancus (Walker, 1856) , a junior synonym, in the Miller Creek Watershed on the Kenai Peninsula and identified using molecular DNA barcoding. We collected an adult male Cladotanytarsus pinnaticornis Bilyj & Davies, 1989 from a distributary of the Yukon River delta. This is the first faunistic record for the USA. We collected Cladotanytarsus larvae from the Kanuti and South Fork Koyokuk Rivers in Kanuti National Wildlife Refuge, Steambath and Kaskanak Creeks in Southwestern Alaska, and Arctic Coastal Plain lakes and streams ( Arctos 2023). We collected larvae from Caswell, Goose, Meadow, and Little Meadow Creeks in the Mat-Su Valley, and Soldotna and Crooked Creeks on the Kenai Peninsula. Butler et al. (1980) suggested that specimens of Cladotanytarsus they collected from tundra ponds were a new species. However, no consequent report of this species could be found. The larvae inhabit fresh and brackish waters, and hot springs. They construct sessile cases of fine detritus ( Epler et al. 2013).
