Abstract

The 33 species of Prosimulium Roubaud known from Canada and Alaska are reviewed. These are segregated into four subgenera: Distosimulium new subgenus, containing one species; Parahelodon new subgenus, containing three species; Helodon Enderlein, containing seven species of which clavatum, martini, and susanae are new, and one (known only from the larva) remains undescribed; Prosimulium s. str., containing 25 species of which approximatum, constrictistylum, impostor, mysticium, neomacropyga, and woodorum are new. Species of the last subgenus are segregated into three species groups. A lectotype is designated for P. ursinum (Edwards). Descriptions, distribution maps, keys, and 158 illustrations for the identification of the known adults, pupae, and larvae are provided.

Résumé

Les 33 espèces de Prosimulium Roubaud connues du Canada et de l'Alaska sont redécrites ici. Elles sont divisées en quatre sous-genres : Distosimulium n. sgen., avec une espèce; Parahelodon n. sgen., avec trois espèces; Helodon Enderlein avec sept espèces, dont clavatum, martini et susanae sont nouvelles et dont une reste non décrite; Prosimulium s. str. contenant 25 espèces, dont approximatum, constrictistylum, impostor, mysticum, neomacropyga et woodorum sont nouvelles. Les espèces de Prosimulium s. str. sont classées en trois groupes. Un lectotype est désigné pour P. ursinum (Edwards). Des descriptions, des cartes montrant la répartition géographique, des tables dichotomiques et 158 illustrations sont présentées pour l'identification des différents stades des espèces actuellement connues.
