CHIRONOMIDAE (DIPTERA) OF LOUISIANA I. SYSTEMATICS AND IMMATURE STAGES OF SOME LENTIC CHIRONOMIDS OF WEST-CENTRAL LOUISIANA JAMES E. SUBLETTE, Eastern New Mexico University, Portales. New Mexico Nomenclature The chironomid fauna of the Southern United States was poorly known until the publication of Henry K. Townes' monu-mental work on the Nearctic Chironomini ( =Tendipedini ) in 1945. Since that time several published works have added to the knowledge of a regional chironomid fauna. These are reviewed and the species synono-mized as they apply to the present study in the systematic treatment which follows. Since Townes reviewed the synonomy of each species of Chironomini, I shall not duplicate here his lists but rather cite only those relevant contributions since 1945. For those subfamilies and tribes not included in Townes' work, as complete a synonomy as is known to me is given. Citations of the list in my 1955 paper are not given in the synonomies which follow as they were dup-licated in my 1957 paper, nor are the species listed by Townes (in Johannsen and Townes, 1952) given since this publication is an abridgment of his 1945 paper. Nomenclature of the Chironomidae is in an extremely confused state. Notable points of controversy are the Meigen 1800 versus 1803 names and the application of Tany-tarsus by Townes in a very different sense from customary usage of approximately the previous half-century. The Meigen names controversy as well as that of Tanytarsus are now before the Inter-national Commission on Zoological Nomen-clature. In the interim, I am following usage that appears to be consistent with the opin-ion of a majority of dipterologists, as evi-denced by publication and personal cor-respondence. Two recent publications, Brundin (1956) and Fittkau (1962), have greatly clarified the status and position of many taxa of the Orthocladiinae and Tanypodinae, respective-ly. Unfortunately, an application of these works to the Nearctic fauna would necessi-tate a re-examination of most of the types of North American chironomids. To have a solid systematic treatment I am following mostly the taxa of Freeman (1955-1961) that are based largely on adults. I have at-tempted to indicate position of appropriate species in the Brundin-Fittkau nomenclature. The following genera and subgenera as used in this paper are compared with those given in Johannsen and Townes (1952), the most inclusive modern work on adult Chironomidae of North America.
