Maximum likelihood phylogenetic trees of the family Planorbidae using COI (655 bp) sequences and using the General Time Reversible (GTR) model [95] with discrete gamma distribution ([+ G] = 0.24). Bootstrap values (10,000 replicates) > 70 are shown next to the branches. GenBank sequences are displayed with their accession number (not italicized). Sequences without accession number were obtained during this study and can be linked to pictures of freshwater snails shown in the Fig. 1. The number or letter after the S-prefix denotes site name and respective the code name is given (BPF = B. pfeifferi, FOR = B. forskalii, BGL = B. globosus, TRU = B. truncatus, TRO = B. tropicus, and GYR = Gyraulus sp.)
