          The 13 genera of the family Clusiidae (Diptera: Schizophora) are keyed with all characters illustrated and/or photographed. Keys are provided in two forms: a traditional dichotomous key and a non-dichotomous Lucid key.  The 36 species of Clusiidae (the six species of the Clusiodes melanostomus complex are treated as a single unit) occurring in Canada and the United States  are similarly keyed and illustrated. Genus and species pages are given for each taxon, providing photo galleries, descriptive notes and distributional maps.
