SI Figure 5. Jane4 Alternative Co-Phylogeny. Cospeciation events are indicated by a white circle. Duplication events are indicated by a solid-colored circle. Duplication and Host Switch events are indicated by a solid-colored circle and an arrow. Loss events are indicated by a dashed line. Failure to Diverge events are indicated by a squiggly line.
