Gainesville 3-XII-1983 Coll. M.C. Thomas", 1; "FLORIDA: Alachua Co. San Felasco Hammock 4-11-1983 M.C. Thomasn, 3; same, except date is 12-II-1983. These specimens comprise a new state record for R. sayi, which Bousquet (1990) recorded from most of the eastern United States except for Florida and Georgia.
