Description of Pupal Stages of Nycteribia quasiocellata Theodor and Eucampsipoda sundaicum Theodor, and Key to Identification of Puparia of Eurasian Nycteribiid Flies

Bat flies (Diptera: Hippoboscoidea) are highly specialized ectoparasites only associated with bats (Mammalia: Chiroptera). These pupiparous flies are born as larvae but immediately pupate. The puparia have not been described for most species. We report new findings of bat fly puparia in Asia, with descriptions of the puparium of highly distributed species Nycteribia quasiocellata Theodor, 1966 from Siberia and adjacent territories and Eucampsipoda sundaicum Theodor, 1955 from Southeast Asia with a key to the determination of puparia of Eurasian nycteribiid flies known so far.
