This checklist was derived from the electronic manuscript which was conventionally published in April 1998 as Volume 16 of the series Arthropods of Florida and Neighboring Land Areas.

Peck, S. and M. Thomas. 1998. A distributional checklist of the beetles (Coleoptera) of Florida. Arthropods of Florida and Neighboring Land Areas. Volume 16. Florida Department of Agriculture and Consumer Services. Gainesville. 180 pp.

At cite:452764 (1), but the two reference citations are used in various places, so we might as well leave them both. (If this were Wikipedia, we could create a redirect to eliminate the duplication. Perhaps in the future!)
Good job on the bibliographic details--we were much more "quick and dirty" about those in the old days, circa 2004--BugGuide scholarly standards have been raised since then.
