We describe a new genus Alaskacladius gen. nov., based on the adult stages collected from Alaska, USA, and BritishColumbia, Canada. Molecular and morphological assessment of adult specimens supports the presence of a new genus.Alaskacladius gen. nov., is related to the genera Doithrix Sæther & Sublette, 1983; Georthocladius Strenzke, 1941;Parachaetocladius Wülker, 1959; and Pseudorthocladius Goetghebuer, 1932. Based on the molecular analysis result andintergeneric K2P distance obtained from Cytochrome Oxidase I (COI) genes, Alaskacladius is closest and forms a sistergroup with Doithrix.
