Detailed view of the seven Bulinus species within the maximum-likelihood estimates (1000 bootstrap replicates) using combined data matrix (All genes together with TVM + G as selected model). An asterisk indicates node support ≥ 80 for all methods used (parsimony, distance, and likelihood bootstrap analyses), with Indoplanorbis exustus as outgroup. Scale bar indicates 2 substitutions per 100 sites. Each terminal branch in the tree is marked using a letter country code (C: Cameroon, E: Egypt, and S: Senegal). Each internal branch represent monophyletic groups.
