Psychomyiidae

thumb|Tinodes assimilis

The Psychomyiidae are a family of tube-making caddisflies. Members of this family are typically very similar to polycentropodids, most of them can be differentiated by the spur formula is 2-4-4, thyridial cell short, absence of the forewing fork I, and hindwing forks I and IV (except in Eoneureclipsis). Male genitalia has elongate preanal appendages, and reduced tergum IX. The larvae differ by the submental sclerites separated, foretrochantin broad, and the pupal mandible apex whip-like. Larvae construct long silken galleries.
