Figure 3 in A taxonomic revision of fossil freshwater pearl mussels (Bivalvia: Unionoida: Margaritiferidae) from Pliocene and Pleistocene deposits of Southeastern Europe

Figure 3. Distribution ranges of Pseudunio taxa. The range of each species is illustrated based on the corresponding river drainages: 1 – former range of P. auricularius based on fossil and recent records (Araujo and Moreno, 1999; Araujo and Ramos, 2001; Prie et al., 2018); 2 – range of P. homsensis based on recent records (Vikhrev et al., 2017); 3 – range of P. marocanus based on recent records (Lopes-Lima et al., 2018); 4 – former range of P. flabellatiformis with its synonyms (M. moldavica syn. nov., M. robusta robusta syn. nov., M. robusta speensis syn. nov., and M. robusta tirassica syn. nov.) based on fossil records (Bogatchev, 1961; Chepalyga, 1964, 1965, 1967; Bolotov et al., 2016). Stars indicate records of P. flabellatiformis from the Pliocene (blue) and Pleistocene (red) deposits of Southeastern Europe (Bogatchev, 1961; Chepalyga, 1964, 1965, 1967; Bolotov et al., 2016).
