Linognathus petasmatus: "the true host of the African louse species Linognathus petasmatus is unknown. Disagreement exists as to whether the known specimens were recovered from scimitar oryx (Oryx dammah) or addax (Addax nasomaculatus). If the oryx is the host, the louse would’ve been eliminated when the oryx was rendered extinct in the wild, while if it is the addax, the louse is – in fact – extant, though critically-endangered along with its antelope host"
