Herein we describe three new species of Smicridea McLachlan (S. (S.) lata, S. (S.) spatulata, and S. (S.) dividua) from Panama in the nigripennis species group (Trichoptera: Hydropsychidae). The nigripennis species group is characterized by having a rather complex phallic apparatus, open anteroventrally and posterodorsally, with ventral and lateral portions produced into lobes, and with spines and other structures arising from the endothecal membranes. All three species resulted from a 2017 survey of Omar Torrijos and Santa Fe National Parks. Twenty-six species of Smicridea, nine of them endemic, are now known from Panama.
