Abstract
Adults of Sphagnophylax meiops gen. et sp. nov. are described from the Yukon and Northwest Territories of Canada. The habitat is small, low-lying tundra basins where water lies on the surface for brief periods in the spring, later receding into a saturated layer of organic debris. Affinity of Sphagnophylax with the four tribes of the Limnephilinae is questionable. Apomorph characters shared with the Chaetopterygini are open to conflicting interpretations, and others are discordant or unique in the Limnephilidae, indicating that Sphagnophylax is best assigned as Limnephilinae incertae sedis until more information is available.
