Sympatric Biomphalaria species (Gastropoda: Planorbidae) in Lake Albert, Uganda, show homoplasies in shell morphology

The three known sympatricBiomphalaria species that occur in Lake Albert; B. choanomphala, B. stanleyi and B. sudanica, were studied using both molecular (COI, 16S and ITS) and shell morphometric data. An unidentified sample of 18 Biomphalaria specimens from Lake Albert were divided in three morphotypes according to aperture height and coiling rate and subsequently identified through molecular inferences and morphometry. The 18 specimens were identified as follows; six specimens were identified as B. sudanica, seven species as B. stanleyi, four as B. cf.
