Figure 5. A simplified tree showing relationship between major lineage and geographic distribution in the study. The letter beside each lineage line indicates correspondence to the letter in Figure 4. The bootstrap value was indicated at each node (when > 50%). Open circle, locality of M. binodosus specimens; closed circle, locality of M. furciferus specimens; open square, locality of M. fujisanus specimens; closed square, locality of M. taniguchii specimens.
