Trichoptera are the seventh largest insect order with more than 15,000 described species distributed worldwide. The family Polycentropodidae is found in all biogeographic regions, and has more than 600 described species. Two genera are known to reach their highest diversity in the Neotropics: Cernotina Ross, 1938 and Cyrnellus Banks, 1913. This study aims to revise the taxonomy of the genera, as well as understand the species phylogenetic relationships. Species are being illustrated and described. The phylogenetic component focuses on data from morphological characters, with parsimony (Fitch parsimony) and Bayesian (Markov k model) approaches with different parameters. To date, 76 species (67 for Cernotina and 9 for Cyrnellus) are known, in which about 35 are not described (33 for Cernotina and 2 for Cyrnellus).
