Description of Trichophoromyia uniniensis, a new phlebotomine species (Diptera: Psychodidae: Phlebotominae) of Amazonas State, Brazil.

BACKGROUND: A new species of phlebotomine sand flies belonging to Trichophoromyia Barretto, 1962 genus is described, based on males collected in Jaú National Park, Amazonas state, Brazil. METHODS: The Sand flies were mounted in Canada balsam. They were measured with a binocular Olympus CH-2 microscope with the aid of a micrometer objective and the drawings were done with the help of a camera lucida. RESULTS: This new species named Trichophoromyia uniniensis sp. nov. is closely related to Trichophoromyia omagua (Martins, Llanos & Silva, 1976). The former can be distinguished from the latter by the shape of its paramere that has the lower apical region turned up in the new species. CONCLUSION: With the new species here described a total of 39 species belonging to the Trichophoromyia genus are now known, most of them present in the Amazon rainforest.
