FIGURE 4 in An integrative taxonomic approach to the identification of three new New Zealand endemic earthworm species (Acanthodrilidae, Octochaetidae: Oligochaeta)
FIGURE 4. Simplified phylogeny of New Zealand earthworms including the three newly described species M. felix, D. gorgon and O. kenleei (NJ tree based on 16S rDNA). The 16S rDNA sequences obtained for the three newly described species were compared to similar sequences obtained by Buckley et al. (2011). One representative for each major clade of New Zealand endemic earthworms was included in the analysis (see Buckley et al. 2011). The tree is drawn to scale, with branch lengths in the same units as those of the evolutionary distances used to infer the phylogenetic tree. The evolutionary distances were computed using the Maximum Composite Likelihood method (Tamura et al. 2004) and are in the units of the number of base substitutions per site. There were a total of 441 positions in the final dataset.
