FIGURE 36. a Phylogenetic hypothesis of Philisca species and outgroups in the tribe Gayennini. Support values for groups expressed as Bremer support in units of fit x 100 (top) and GC frequency differences (bottom). Only the basal branch is shown for outgroup genera with more than one species (indicated by "spp."). Constant of concavity k = 6, Fit = 75.82551, length = 1056. b Constrained analysis forcing the monophyly of the Philisca species endemic to Juan Fernández Archipelago. This resolution is only suboptimal in 0.11 units of fit (equivalent as 11 units in the Bremer support values in Fig. 36a).
