    Abstract We review the developments in caddisfly (Insecta: Trichoptera) systematics starting with Linnaeus through to the present time. We give a brief introduction to the natural history and biology of the order, survey the contributions of prominent caddisfly taxonomists, explore the history of Trichoptera phylogenetics, define synapomorphies for the major caddisfly clades, identify gaps in our knowledge, and make recommendations for the future research in caddisfly systematics. While the pattern of early evolutionary divergences within the order is becoming clearer with phylogenomic data, much work remains to be done to describe unknown caddisfly diversity and to fully resolve their tree of life. This will require the training of a new generation of Trichoptera systematists, particularly in tropical regions, equipped with broad knowledge in natural history, taxonomy, systematics, genomics, and phylogenetics.

    Prior to this publication, six species of microcaddisflies in the genusRhyacopsyche(Trichoptera: Hydroptilidae) had been recorded from Ecuador. Herein, we describe five new species:Rhyacopsyche abditasp. nov.,Rhyacopsyche bellavistasp. nov.,Rhyacopsyche decouxisp. nov.,Rhyacopsyche patulasp. nov., andRhyacopsyche tumidasp. nov.Illustrations of male genitalia are provided with each description. This work brings the total number ofRhyacopsychespecies in Ecuador to eleven, and the world total to 37.

    Two new species of Hydroptilidae,Neotrichia bajasp. nov.andOchrotrichia rivasisp. nov., are described from the Baja California peninsula, Mexico. New country records for Mexico of four species are provided:Leucotrichia muticaFlint, 1991,Neotrichia kimiKeth, 2015,Neotrichia sepulgaHarris, 1991, andOchrotrichia luciaDenning & Blickle, 1972. In this study, 16 Hydroptilidae species were recorded in the peninsula, and nine were new records for the Baja California and Baja California Sur states. This study represents the first microcaddisfly (Hydroptilidae) diversity assessment of the Baja California peninsula.
