Figure 6 from: Nakano T (2016) A new quadrannulate species of Orobdella (Hirudinida, Arhynchobdellida, Orobdellidae) from western Honshu, Japan. ZooKeys 553: 33-51. https://doi.org/10.3897/zookeys.553.6723

Figure 6 - Bayesian inference tree for 5,192 bp of nuclear 18S rRNA and histone H3 and mitochondrial COI, tRNACys, tRNAMet, 12S rRNA, tRNAVal, 16S rRNA, tRNALeu and ND1 markers. Numbers on nodes represent bootstrap values for maximum likelihood and Bayesian posterior probabilities. A species name of Orobdella in red indicates a quadrannulate species; in green, sexannulate; and in blue, octannulate.
