The phantom midges (Diptera: Chaoboridae) are a relatively small fly family composed of 50 extant species in six genera. Larvae are of interest to limnologists and ecologists because of their tolerance to toxicants, predatory avoidance strategies, and the role chaoborids play in zooplankton community dynamics. Relative to mosquitoes, systematists have paid relatively little attention to this group. Recent work on the internal classification of the chaoborids has provided a wealth of character information and putative homologies, but the relationships among the Chaoboridae genera have not been rigorously analyzed and support for the monophyly of the family is weak. Examining exemplar representatives from all previously recognized supra-specific groups; the goals of this study are to establish the monophyly of the “chaoboriform” genera and to provide data to clarify the position of the “chaoboriform” genera within the Culicoidea. The results of a preliminary cladistic analysis of the chaoborid genera using morphological characters from adult, pupal, and larval stages will be presented.
