Fig. 4

Positions of the species studied herein in a two-dimension space defined by the first two axes of a principal component analysis based on 22 adult morphological variables. Size effects were removed when necessary using residuals from the regressions of the corresponding variables on SVL. Mean values (±SE) for factor scores on the first two axes of the populations measured are given in the figure. Green dots and lines: P. guinanensis; red dots and lines: P. putjatia; blue dots and lines: P. vlangalii
