The collection comprises of all the species described by Dziędzielewicz; the lectotypes of the following are designated: Potamophylax carpathicus (Dz.), Acrophylax vernalis Dz., Isogamus czarnohorensis (Dz.), Chaetopteryx polonica Dz. and Annitella chomiacensis (Dz.). I. czarnohorensis, which was given the rank of species is redescribed and illustrated. New species (Hydropsyche bulgaromanorum Mal. and Triaenodes simulans Tjed.) for the Polish fauna were found. A list of incorrect identifications by Dziędzielewicz is presented.
