Abstract. Sixty species of Bethylidae of the genera Acrepyris Kieffer, Allobethylus Kieffer, Ape-
nesia Westwood, Anisepyris Kieffer, Bakeriella Kieffer, Cephalonomia Westwood, Dissomphalus Ash-
mead, Epyris Westwood, Goniozus Forster, Holepyris Kieffer, Laelius Ashmead, LepidosternopsisOg-
loblin, Plastanoxus Kieffer, Prorops Waterston, Prosierola Kieffer, Pseudisobrachium Kieffer, Wiabde-
pyris Kieffer, and Sclerodermus Latreille were collected, primarily in Malaise traps, at 12 sites in
Orange Co., 3 in Seminole Co., one in Osceola Co. and one in Volusia Co., Florida, USA. Lepidos-
ternopsis is recorded for the first time from the Nearctic Region and Lepidosternopsis irradiata
