Figure 3 in Taxonomy, phylogeny and biogeography of Politolana Bruce, 1981 (Crustacea: Isopoda: Cirolanidae)
Figure 3. Unambiguous character change in Politolana sensu stricto, with branch lengths proportional to change. Branch numbers, referred to in the text, are indicated in the box to the left of the branch. Nonhomoplasious characters are marked with black bars, homoplasious characters are marked with white bars, and those characters that are homoplasious in the context of the entire phylogeny, but which are not homoplasious within Politolana sensu stricto, are marked by grey bars. The character number and direction of state change are given to the right of the bar and correspond to the character list (Appendix 1). This clade has a CI = 0.78, RI = 0.78 and RC = 0.61 (with uninformative characters removed).
