Figure 2. Principal component analysis of savanna tiger-cats from the Guiana Shield, with those of eastern Amazonia and the northern savannas, and with clouded tiger-cats (L. pardinoides). PCA clearly shows convergence between the two groups of L. tigrinus, and not with those of L. pardinoides; such a scheme would invalidate L. emiliae as a species in as far as ecological niche dimensions are concerned.
