Table 1 in A redescription of Astyanax gymnodontus (Eigenmann, 1911), new combination, a polymorphic characid fish from the rio Iguaçu basin, Brazil

Table 1. Variable loadings for the principal component analysis of the three morphotypes of Astyanax gymnodontus. Truss measurements (numbers) are indicated with landmarks (letters) shown according to Fig. 1. The following abbreviations were used: maxil. comm.: maxillary commissure; supraoc. process: supraoccipital process. The modular higher eigenvectors of principal component 2 are shown in bold (see text for details).
