A PCA plots of the first principal component (PC 1) versus the second (PC 2) of morphometric analysis for the two species of Kolekanos. The green polygon denotes the distribution within PCAs of K. spinicaudus sp. nov. and the pink polygon of K. plumicaudus. For loadings of all axis and explained variance, see Suppl. material 3. B boxplots (top whisker – maximum value; lower whisker – minimum value; bold horizontal line – median; box – 1st and 3rd quartile) of morphological features where ANOVA t-values where ≤ 0.05; p-value of the one-way ANOVA test is indicated at the bottom of each boxplot.
