Figure 2. Principal Component Analysis (PCA) on 24 morphometric variables of the study samples including paratypes.

The clusters of samples obtained from PCA were assigned to respective taxa based on meristic counts as well as non-quantitative characters of samples following authoritative taxonomic keys. The groups are like T₁, T₂ and T₃ comprising Tor congener, and N₁ and N₂ comprising Neolissochilus congener.
