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. [1] The larvae differ by the submental sclerites separated, foretrochantin broad, and the pupal mandible apex whip-like. [2] [3] Larvae construct long silken galleries.
The type genus for Psychomyiidae is Psychomyia P.A. Latreille, 1829. [4]
Psychomyiella Ulmer, 1908 is considered a junior synonym of Psychomyiia. [5] Phylogenetic analysis of Johanson & Espeland (2010) found the genus Zelandoptila Tillyard, 1924 placed within the family Ecnomidae although the genus was previously placed in Psychomyiidae. [6]
