There have been 136 species of microcaddisflies (Trichoptera: Hydroptilidae) recorded from the Republic of Panama. Herein we describe seven new species from the Mount Totumas Cloud Forest and Biological Reserve, in the upper reaches of the Río Chiriquí Viejo watershed (Costatrichia devestiva, C. dietrichi, Metrichia brocha, M. calla, Neotrichia atopa, Ochrotrichia anticheirion, and Rhyacopsyche totuma). These results are part of an ongoing effort to characterize the aquatic insect fauna of Panama, and to evaluate that country’s major watersheds.
