A new species of parthenogenetic, autogenic and apparently extremely endemic phlebotomine is described from a sandstone cave located in primary terra firme forest to the North of the city of Manaus. Specimens were collected in the aphotic zone of the Refúgio do Maruaga cave by light trap and reared from bat guano. The adult morphology suggests a closer relationship to some Old World Phlebotominae than to species of
Lutzomyia
França encountered in the surrounding rainforest, but it shares characteristics with the recently proposed Neotropical genera
Edentomyia Galati,
Deanemyia Galati and
Oligodontomyia Galati.
