Figure 9 in Geometric and traditional morphometrics for the assessment of character state identity: multivariate statistical analyses of character variation in the genus Arrenurus (Acari, Hydrachnidia, Arrenuridae)

Figure 9. Shape variation of dorsoglandularia D4 in dorsal view (data set 4). (A) scatter plot of canonical variate scores (root 1 vs. root 2). (B) overall pattern of shape similarity among 11 Megaluracarus species and two Dadayella species based on Mahalanobis distances computed from the canonical variate analysis. This UPGMA phenogram (unweightedpair grouping method using averages) groups the three character states discovered in the dorsoglandularia. Branches are labelled according to discrimination order defined by the canonical variates. Symbols in the plot and in the phenogram are as listed in Fig. 8.
