Apolysis sp. (Diptera: Bombyliidae) reared from Quartinia sp. (Hymenoptera: Vespidae: Masarinae)

A pupa containing a pharate adult of a species of Apolysis (Diptera: Bombyliidae), probablyA. capicola Hesse, was reared from a nest of a Quartinia sp. (Hymenoptera: Vespidae: Masarinae) inside a shell ofTrigonephrus sp. (Gastropoda: Dorcasiidae) in Namibia. Since this is the first record of the host of any species ofApolysis , and the first pupa of this genus to be discovered, an illustrated description of the pupa is provided and the implications for the classification of the Bombyliidae are discussed.
