Figure 10 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 10. Shape variation of ventroglandularia V1, V2 and V3 (data set 5). (A) scatter plot of canonical variate scores (root 1 vs. root 2); shape changes relative to the mean shape are shown for both roots. (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 (unweighted-pair grouping method using averages) groups the nine character states discovered in the distribution patterns of ventroglandularia. Branches are labelled according to discrimination order defined by the canonical variates. Symbols in the plot and in the phenogram are as follows: solid green triangles, Arrenurus (Dadayella) adrianae; solid red rhombuses, Dadayella aztecus; lilac en-dashes, Arrenurus (Megaluracarus) anae; open blue circles, Megaluracarus anitahoffmannae; horizontal blue lines, Megaluracarus catoi; open red squares, Megaluracarus colitus; solid grey squares, Megaluracarus costeroae; open green rhombuses, Megaluracarus maya; solid black circles, Megaluracarus neoexpansus; blue asterisks, Megaluracarus olmeca; green hyphens, Megaluracarus tabascoensis; open pink triangles, Megaluracarus urbanus; purple plus signs, Megaluracarus zitavus.
