Figure 12 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 12. Multivariate variation in the 15 interlandmark distances measured between postocularia R2 and dorsoglandularia D2, D3 and D4 (distance set 2). (A) scatter plot of canonical variate scores (root 1 vs. root 2); distances with the highest standardized factors are illustrated for both axes. (B) overall pattern of similarity among 11 Megaluracarus species and two Dadayella species based on Mahalanobis distances computed from the canonical variate analysis. This UPGMA phenogram (unweighted-pair grouping method using averages) groups the 13 character states discovered in the collection of distances from the postocularia and 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. 11.
