Freshwater mussels from South America: state of the art of Unionida, specially Rhipidodontini

“…Diplodon dunkerianus (Lea, 1856) and D. martensi (Ihering, 1893) were only presented by Simpson (1914) and Parodiz (1968), among the authors of Table 2. However, there are more recent references to D. martensi (Mansur 1970, Vaz et al 1987, Mansur 1999, Pfeifer & Pitoni 2003 and D. dunkerianus (Amaral et al 2008).
