A REVISED ANNOTATED CHECKLIST OF THE CHIRONOMIDAE (INSECTA, DIPTERA) OF THE SOUTHEASTERN UNITED-STATES

A revised annotated checklist for the chironomid midges (Diptera: Chir onomidae) of the southeastern United States is presented that includes the states of Alabama, Florida, Georgia, North Carolina, South Caroli na, and Tennessee. Much of the information concerns occurrence and hab itat preference records based upon the authors' data, as well as publi shed and unpublished data. Some information is also presented that inc ludes aspects of biology, habitat preference, bibliographic sources, a nd nomenclatorial changes. Based upon the present work, the chironomid fauna of the southeastern states is comprised of 189 genera (172 desc ribed, 17 informally or unofficially described) and 754 species (505 d escribed, 17 informally or unofficially described, 33 that are assumed for generic or subgeneric presence only, 197 estimated species, and 2 species groups). Several new species synonyms and generic placements are recognized. Thirty-eight genera known from the Nearctic region rem ain unknown from the southeastern states. Diversity of species was gre atest in the subfamily Chironominae, considering named as well as unna med and estimated species. There were no significant changes in overal l regional distribution patterns of subfamilies or habitat preferences from that which has been previously reported. The greatest totals for regional records, habitat types, and state occurrences were the Coast al PIain (378), streams (271), and North Carolina (373), respectively.
