Fig. 5 in Description of Neblinichthys peniculatus, a new species of loricariid catfish from the río Paragua drainage of Venezuela

Fig. 5. Principle Components Analysis of species of Neblinichthys. Most strongly loading measurements and their directions indicated. PC2 represents 6.3% of the total variation and PC5, 1.6% (note, most variation, 81.7% is in PC1, which represents overall size). Barbel length was excluded because of extreme variance and interorbital width was excluded because it was not measured the same throughout the study.
