Non-homoplasious character changes are indicat- ed with black squares; homoplasious characters are indicated with white squares. Trait numbers are indicated above squares, state changes below. The 'M' below the character state changes in (C) indicates a multistate character optimized as an autapomorphy. For trait references, see Table S1 and Table S6; for detailed trees, see Figure S7.
