Zootaxa, (1272), 45-59.https://hdl.handle.net/11299/192352The caddisfly genus Canoptila Mosely (Glossosomatidae: Protoptilinae), endemic to southeastern Brazil, is diagnosed and discussed in the context of other protoptiline genera, and a brief summary of its taxonomic history is provided. A new species, Canoptila williami, is described and illustrated, including a female, the first known for the genus. Additionally, the type species, Canoptila bifida Mosely, is redescribed and illustrated. There are three possible synapomorphies supporting the monophyly of Canoptila: 1) the presence of long spine-like posterolateral processes on tergum X; 2) the highly membranous digitate parameres on the endotheca; and 3) the unique combination of both forewing and hind wing venational characters.enTrichopteraGlossosmatidaeProtoptilinaeCanoptilacaddisflymale genitaliafemale genitaliaNeotropicsAtlantic Forestsoutheastern BrazilArticle
