FIGURE 10. Genetic distance tree of mitochondrial COI gene in Ceratophysella inferred using the Neighbour-Joining method. The bootstrap consensus tree was inferred from 1,000 replicates. The percentages of replicate trees in the bootstrap test are shown next to the branches. The distances were computed using the Kimura 2-parameter method. Symbols indicate localities from which the specimens were collected: open circle, Japan (Otsu); closed circle, Japan (Nagasaki); open square, Australia; closed square, New Zealand; open triangle, Chile; closed triangle, Argentina; open diamond, France. See Table 1 for sources of sequence data.
