BI MAP tree from analysis of concatenated Fcox1/nd1 DNA sequences using Hyridella menziesi (Unionoida: Hyriidae) as the outgroup. An asterisk above a branch = BI posterior probability (×100) ≥ 95. An asterisk below a branch = ML BSP (1000×) ≥ 70. Black indicates lineages that are dioecious, contain an F-orf in the F mt genome and display DUI (=M mt genome present). Orange indicates lineages that are hermaphroditic, contain an H-orf in the F mt genome and display SMI (=M mt genome absent). Hermaphroditism, H-orfs and SMI concurrently evolved four distinct times. Proportional likelihood values (all nodes significant) are given in rectangles for the character state estimates at eight nodes (orange diamonds, character states = hermaphroditism, H-orf and M genome absent; black diamonds, character states = dioecy, F-orf, and M genome present, BSP = Bootstrap Support Percentages).
