A new species of Sarcofahrtiopsis Hall (Diptera: Sarcophagidae) living in roosts of Spix's disk-winged bat Thyroptera tricolor Spix (Chiroptera) in Costa Rica

Sarcofahrtiopsis thyropteronthos sp. n. is described from Costa Rica. All specimens were bred from faeces taken from young, tubular leaves of musoid plants (genera Heliconia and Calathea) used as roosts by Spix's disk-winged bat Thyroptera tricolor Spix. Larvae were observed in practically all roosts suggesting a highly specialized association.
