Fig. 11. Plot of specimen scores on the first two axes of the principal components analysis (PCA) of type series of Heteromys oasicus and H. anomalus and its synonyms. Adults in age classes 4–6 were used here. PC1type represents a size factor and was multiplied by —1 so that smaller specimens appear to the left and larger ones to the right (table 4). Axes are scaled relative to their eigenvalues (proportion of variation among specimens explained), and specimens are marked by the first letter of the following respective series: a, anomalus; b, brachialis; h, hershkovitzi; j, jesupi; o, oasicus; t, Trinidad (Caura, used as an additional sample of the nominotypical anomalus). Note the small size of specimens of H. oasicus, especially in contrast to the holotype of H. anomalus.
