PRELIMINARY PHYLOGENETIC HYPOTHESIS
1. We scored the Sanderia species incorrectly for the
character of septa termination.
In the undescribed species,
the septa terminate toward the tentacle, not toward the rhopalium.
This is typical in the species of Chrysaora as well.
However, for S. malayensis,
Mayer (1910) describes the septa as
terminating in the rhopaliar radii, and Stiasny (1937, figure 10)
illustrates it similarly. Rescoring the character and re-running our
tree searches finds two most parsimonious trees.
The strict consensus
of those two trees is identical to the tree appearing in the published
2. C. plocamia reaches sizes to one meter in
bell diamter, which is larger than we originally scored it. Thanks to Hermes Mianzan for
pointing this out for us.
3. The author addresses were inadvertantly switched. The single cross should
indicate UC Berkeley, whereas the double cross should indicate CSU
Northridge and Cabrillo Marine Aquarium. Lisa is associated with all three
institutions, whereas Allen is associated with UC Berkeley.
