Lutzomyia maruaga (Diptera: Psychodidae), a new bat-cave sand fly from Amazonas, Brazil.

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.
