Pintomyia (Pifanomyia) paleotownsendi, a new sand fly from the Miocene amber of Dominican Republic (Diptera: Psychodidae: Phlebotominae). 
Phlebotominae includes some vector species, mainly that of leishmaniases, with a very old host-parasite relationship.  Some species fossils of this subfamily have been recently described and this paper presents the description of a new sand fly Pintomyia (Pifanomyia) paleotownsendi sp.  nov in amber.  The gonostyle present four spines, being one apical, one external superior implanted close to the apical third, one external inferior in the middle of the structure and one internal implanted in the basal third.  This disposition of the spines may separate the new species from others in the sub genus.
