Paleoleishmania
Paleoleishmania is an extinct genus of kinetoplastids, a monophyletic[1] group of unicellular parasitic flagellate protozoa.[2] All trypanosomes are heteroxenous (requiring more than one obligatory host in order to complete life cycle) or are transmitted through some variation of a vector.[2] During the fly's struggle to escape from the resin, the alimentary tract was ruptured and some P. neotropicum flagellates leaked from there into the hemocoel.P. neotropicum and L. adiketis lived in an environment similar to modern moist tropical rain forests.They probably developed within the proboscis from an earlier meal of the fly, however they may have been "infective promastigotes" which occur naturally in the mouthparts of some Lutzomyia species.
