a sand fly fossil was found in amber, a vegetal resin, which allows all the external phlebotomine structures to be seen. the piece that contains the new species is 14 mm long ′ 8 mm wide ′ 3 mm high. all the structures from the head, thorax, and abdomen were examined under the microscope and measured with a calibrated micrometric eye-piece. the morphological aspects of the new species suggest its inclusion in the pintomyia genus, pifanomyia subgenus though it is not possible to include it in any of the series known for this subgenus. the presence of two atrophied spines on the gonostyles and gonocoxites without tufts of setae permit the exclusion of the new species from the other species of the subgenus pifanomyia. the new species is named pintomyia (pifanomyia) brazilorum sp. nov.
