Deyrup: List of Florida Ants 43 AN UPDATED LIST OF FLORIDA ANTS (HYMENOPTERA: FORMICIDAE) MARK DEYRUP Archbold Biological Station, P.O. Box 2057, Lake Placid, FL 33862 ABSTRACT A list of ants of Florida published in 1989 is replaced to accommodate 49 additional species now known from Florida, and 34 name changes in species already on the 1989 list. Cur- rently, 218 species of ants are reliably reported from Florida. Key Words: exotic species, faunistics RESUMEN Se presenta una nueva lista de las hormigas de Florida para reemplazar una lista publicada en 1989. La nueva lista incluya 49 mas especies y 34 cambios de nomenclatura. Al presente, 218 especies de hormigas son sabidas a hallarse en Florida.
