Notes on the sand fly fauna (Diptera:Psychodidae) in the State of Rio Grande do Sul, Brazil.

Proceeding with the study of taxonomy and geographical distribution of American phlebotomine sand flies, a trip was made to the Aparados da Serra National Park and to the Turvo State Park (State of Rio Grande do Sul, Brazil) between 23 January and 4 February 1986. Both parks comprise areas of primitive forest and very little is known about the phlebotomine fauna in this region. Only two reports were published, more than 50 years ago, by R di Primio (1932, 1937) describing the finding of three different species of sand flies: Lutzomyia fischeri (Osório and São José do Norte municipalities), L. intermedia (Torres and São José do Norte municipalities) and L. migonei (São José do Norte). Recently, Young and Ducan (1994) published a guide concerning the identification and geographical distribution of the genera Lutzomyia in Mexico, West Indies and Central and South Americas, but very little was available about the phlebotomine fauna in Rio Grande do Sul. Thus, we decided to acomplish some captures to contribute to the knowledge of the sand fly fauna of this southern Brazilian state.
