Figure 3 - Neighbour-Joining tree (Kimura 2-parameter model) of a 1499 bp concatenated fragment (504 bp of the mitochondrial cytochrome c oxidase subunit I (COI) gene, 408 bp of the mitochondrial 16S rDNA gene, 587 bp fragment of the nuclear internal transcribed spacer 1 (ITS1) region) for the land slug subgenus Mesarion. Bootstrap values ≥ 70% are shown at the nodes. For sample codes see Table 1.
