Geophylogeny of Hawaiian katydids and their relatives, generated from PGT [21]. Shaded areas in East Asia inset represents the distribution of Ruspolia and Euconocephalus on the coastal and island regions. Vertical branches in the geophylogeny of Hawaiian katydids represent branch length. Divergence time in dated internal node is shown in million years (my). The geological age of each island is shown next to the islands. Species names associated with the letters at the tips of the geophylogeny are listed in the lower-left of the figure
