| mitochondrial dna phylogenetic structuring suggests similarity between two morphologically plastic genera of australian freshwater mussels (unionoida: hyriidae). | in the lake eyre basin, the australian hyriid genus velesunio is represented by three undescribed species, each of which are highly divergent genetically, but morphologically similar to velesunio wilsonii (lea 1859). a fourth species, velesunio ambiguus (philippi 1847), occurs not only in the lake eyre basin but throughout much of eastern australia, including the murray-darling basin. in this study, we show that another hyriid, alathyria jacksoni (iredale 1934), which is sympatric with v. ambigu ... | 2004 | 15288065 |
