A. A. flavipes subspecies— A. f. flavipes , A. f. leucogaster, A. f. rubeculus

Discriminant Function Analysis (DFA) of the three A. flavipes subspecies indicated that 100% of females and males were clustered into the 3 subspecies groups correctly (individual posterior probabilities not shown), based on the Mahalanobis distance of each individual from the centroid of the a priori species group. For all three subspecies, the lowest posterior probability supporting an individual being correctly classified was 0.99 in males and females.

Canonical Variates Analysis (CVA) of the three A. flavipes subspecies indicated that 100% of the variation in dental characters was explained in the first two canonical roots for males and females. Variation was well resolved for both sexes, as eigenvalues for the first two canonical roots were well above 1 (males: root 1, 11.4; root 2, 6.90; females: root 1, 37.8; root 2, 18.4) and about two-thirds of the variation was explained in the first root (62% for males; 67% for females).

Figures 4–5 show scatterplots of canonical roots 1 and 2 within A. flavipes ; all three recognised subspecies are well clustered and very clearly separated for males and, in particular, females.
