This tribe of the Psychodidae is denned and classified, with keys to and descriptions of six genera. The structure of the labellum is employed for the first time in classification, and other characters of the male and female genitalia, the wings, and the head are considered. It is postulated that the tribe arose from a Brunettia -like. ancestor, that one line of development led to Trichopsychoda and possibly to Lepidopsychoda, and that the main phylogenetic line gave rise to Philosepedon, Threticus, Psychoda, and the new genus Eurygarka (type, Psychoda helicis Dyar 1929). Species assigned to each genus (except Psychoda ) are listed, with bibliography and distribution for each species. Other new generic reassignments include 1 species to Trichopsychoda, 11 to Philosepedon, and 7 to Threticus.
