New collection records for Calusamyia hribari Coher (Diptera: Keroplatidae) are presented. Sufficient material has been amassed to make some statements about the species’ distribution, seasonality, and morphology. Calusamyia hribari occurs throughout the inhabited Florida Keys, from Key Largo to Key West. New island records include Boca Chica Key, Crawl Key, Summerland Key, Geiger Key, Dredger’s Key, Upper Matecumbe Key, Key Largo, Long Key, Tavernier, Windley Key, and Fat Deer Key. As yet it has not been collected from any uninhabited islands within wildlife refuges. About five times more males than females have been collected. Most specimens have been collected in the summer months, with May being the peak of abundance in traps. Females have two spermathecae, similar to other keroplatids.
