| ABSTRACT Pintomyia (Pifanomyia) duckei Oliveira, Alencar and Freitas sp. n. from Adolpho Ducke Reserve, Manaus, Amazonas state, Brazil, is described and illustrated based on three male specimens, the holotype and two paratypes. The paratypes have abnormalities in the external genitalia, one with asymmetric bilateral anomaly (different anomalies in each of certain paired structures) and the other with unilateral anomaly (anomaly in one of the paired structures). The new species probably belongs to the Serrana Series, integrating the list of the species whose males possess gonostylus with two stout spines (one apical and other subapical), as well as a small and very thin spine on the inner surface of the basal half. |
