AB: The caddisfly family Calamoceratidae consists of 8 extant genera, of primarily tropical distribution. Three of these genera, Banyallarga, Heteroplectron, and Phylloicus, are found exclusively in the New World, with the majority of species diversity in the Neotropics. Adults of the two most diverse genera, Anisocentropus and Phylloicus, are remarkable for their colorful, dramatic wing patterning, and the males of Phylloicus also exhibit elaborate abdominal scent structures. Calamoceratid genera have not previously been defined by synapomorphies and their taxonomy has been complicated by inadequate description and the loss of type material. Morphological data were collected to recover relationships among the eight extant genera of Calamoceratidae. 39 calamoceratid species and 16 outgroup taxa were scored for 190 larval and adult characters. Anisocentropus and Phylloicus were found to be sister genera, rejecting the previous hypothesis that Anisocentropus is sister to the other seven calamoceratid genera. Heteroplectron was not recovered as monophyletic.
