Williams This thesis presents the first statewide survey of the ant fauna of Alabama in over seventy years. Since the first state survey by L.C. Murphree (in the 1930’s) to present, 154 species have been reported. Fifty-nine of the species presented are new records for the state. Specimens were collected from every county over a period of three years. Past collection records were also examined and incorporated into this thesis. Distribution data, natural history notes, and identification keys for all the species reported in Alabama are presented. v ACKNOWLEDGEMENTS I would like to thank my advisor, Dr. Michael L. Williams, for accepting me as his student and for his support and guidance over the years. I want to extend my gratitude to my committee members: Dr. Wayne E. Clark and Dr. George Folkerts. I would also like to thank my friends and associates for their help and friendship while here at Auburn including: Nicholas Sharp, Nathan Burkett, Andy Boring, Demian Kondo, Elly Maxwell, Shawn Dash, Dr. Charles Ray, Dr. Gary Mullen, Dr. Arthur Appel, and Joe MacGown.
