The female of Evandromyia (Aldamyia) aldafalcaoae (Santos, Andrade-Filho & Honer) is described for the first time on the basis of specimens captured on the Nhumirim Farm, in the Pantanal region of the Mato Grosso do Sul State, Brazil. The female of this species, differently from others of the Aldamyia Galati, 1995, presents a highly transparent common sperm duct and basal part of the individual sperm ducts, which are thus difficult to observe. An identification key for the females of this subgenus is presented.
