Paramonovius nightking is a species of bee fly in the family Bombyliidae that is endemic to a restricted area of western Australia.

Based on morphology, it is the sister genus to Sisyromyia.

This unusual flight time may have contributed to this species being so rare in collections.

The specific epithet, nightking, references the Night King from the American fantasy drama Game of Thrones as a reference to these habits.
