Lipoptena cervi (Diptera), a potential vector of Megatrypanum trypanosomes of deer (Cervidae).

In three different areas in northern Germany, hippoboscids were collected from red deer (Cervus elaphus). Typanosomatids were demonstrated in the midgut and hindgut of 9/37 Lipoptena cervi. The trypanosomatids were morphologically similar to vector forms of the subgenus Megatrypanum that had been found in tabanids at the same location 5 years previously. Hippoboscids are therefore potential vectors of Trypanosoma (Megatrypanum) spp. that infect red deer.
