Phylogenetic relationships of Bulinus globosus and Bulinus nasutus productus from the Lake Albert region in this study (in bold) and GenBank reference sequences (with accession numbers, place and countries of origin where available) inferred using 631 bp of cytochrome c oxidase subunit 1 and maximum likelihood with the Hasegawa–Kishino–Yano model [22]. Only bootstrap values (10,000 replicates) > 50 are shown
