[1] The specimen was collected from an unidentified amber mine in the Cordillera Septentrional north of Santiago de los Caballeros.

[1] The specific epithet "falcaorum" was coined by the author in honor of Alda and Alberto Falcão, to recognize their contributions to Phlebotominae understanding.

The specimen displays pre-apical bristles, and four spines on the style, these features combined with the AIII flagellomere being over half the length of the head.

Within the genus, it is placed in the subgenus Pifanomyia, based on the posterior femurs lack of spines, but the species does not resemble the known modern species-group series.

[3] In contrast P. brazilorum, P. killickorum, Lutzomyia filipalpis, L. miocena, L. paleopestis, L. schleei, and L. succini all possess an Sc which meets the R1 vein.
