Abstract Four new protopsyllidioid species, Paraprotopsyllidium spinosum gen. et sp. nov., Angustipsyllidium minutum gen. et sp. nov., Burmapsyllidium setosum gen. et sp. nov., and Maliawa akrawna gen et sp. nov. are described from the mid-Cretaceous Burmese amber, and assigned to a new family, Paraprotopsyllidiidae fam. nov., that we establish. These taxa are characterized by their narrowed fore and hind wings, bearing a fringe of long setae; the possible functions of these bristles are explored in this paper. The population dynamics, the potential feeding diet and the biogeographical distribution of this family are briefly discussed.
