Recent work on a catalog of the Neotropical caddisflies has resulted in the recognition of the need to make numerous lectotype designations, new names for homonyms, specific and generic synonymies, transfers of species between genera and genera between families, and placement of many long ignored names of Muller and others. Rationales are presented for all actions, many of which had been known for years as the result of examination of types, but no opportunity had arisen to publish them, others became apparent as a result of the cataloging. This opportunity is taken to present all of those known to us to avoid having them hidden in a general catalog. They are presented alphabetically by family and then alphabetically by the name of the species or genus requiring action. Acronyms of museums and collections cited in the text are detailed in the Acknowledgments.
