Pseudostenophylax is a of northern caddisflies in the Limnephilidae, containing at least 80 described . The genus was established by Martynov in 1909 with Pseudostenophylax fumosus as the type species. Species are primarily distributed across northern regions of North America and Eurasia, with notable diversity in Japan and alpine regions. Research on Japanese species has revealed strong phylogeographic patterns linked to mountain formation and glacial history.
