Vol. 6, No. 1, March 1992 29 A Preliminary Checklist of the Caddisflies (Insecta:. Trichoptera) of Oklahoma David E. Bowles United States Air Force Arrnstrong Laboratory, Occupational Medicine Division, Environmental Biology Branch, Brooks AFB, TX 78235 and Michael L. Mathis Department of Biological Sciences, University of Arkansas, Fayetteville, AR 72701 Abstract One hundred forty-five species of caddisflies representing 15 families and 46 genera are reported from Oklahoma. Thirty-nine species are new state records. Families having the greatest species richness were Hydroptilidae (44 species), Leptoceridae (31 species), Hydropsychidae (26 species), and Polycentropodidae (13 species).
