Canonical Discriminant Analysis (CDA) based on morphometric measurements. A scatterplots of individual male specimens, with points connected to the centroid of their assigned group B relative contribution of each morphometric variable to the first two canonical functions for males C scatterplots of individual female specimens, with points connected to the centroid of their assigned group D relative contribution of each morphometric variable to the first two canonical functions for females. SVL = snout–vent length; HL = head length; HW = head width; TD = tympanum diameter; ED = eye diameter; IOD = interorbital distance; EN = eye–nostril distance; IND = internostril distance; ESD = eye–snout distance; FAL = forearm length; THL = thigh length; SHL = shank length. Colors indicate mitochondrial Leptodactylus fuscus clades: gray = L. fuscus clade 1, black = L. fuscus clade 2, blue = L. fuscus clade 3.
