FIGURE 8. NC-Ward clustering of 61 samples of the two remaining Cardiocondyla nuda species complex after C. nuda has been removed from analysis. The lower of the two main branches belongs to C. atalanta Forel, the upper one to C. paranuda. The left column of bars indicates the final clustering hypothesis for K=2 (C. atalanta vs. C. paranuda) determined by a controlling linear discriminant function (LDA), and the right column of bars the classification by non-hierarchical NC-K- Means clustering. The classification errors in in NC-Ward and NC-K-Means are both 3.3%.
