Of the three discriminant function (DF) roots computed for the three remaining characters, only the first was statistically significant (F = , Wilk's lambda = , p < ). The correct classification results ranged from to with an overall rate of (Table 1). No populations were grouped with La Paz, which also failed to group with itself. The plot of DF I (Fig. 2) with 95% confidence ellipses shows complete overlap among all sites with no discernible patterns. The morphometric discriminant function analysis computed five functions to account for 100% of the variation. DF I, II and III described a total of of the variation (Table 2) and were highly significant (Table 3).
