FIGURE 4. Summary neighbor-joining tree of sequences of mitochondrial cytochrome oxidase subunit 1 for Pentalonia specimens, with host plant and geographic origin. Colored rectangles give a visual indication of host family (colors as in Figure 1). Numbers represent number of specimens represented by each host group within the major cluster (identified by letter 'A' through 'E'). Cluster 'A' corresponds to individuals identified as P. nigronervosa, cluster 'B', individuals identified as P. caladii.
