FIGURE 4. Ordination of individual specimens and OTU centroids of four of the mitochondrially defined candidate species of the N. melanoleuca complex along the first two canonical variates. CS5-peroescobari was omitted due to the small available sample size. Canonical variates 1 and 2 account for 57.9 and 22.8% of total variance, respectively. Enlarged symbols indicate OTU centroids.
