Fig 4

(A) Canonical plot of phenotypic variation of the Z. ceylonensis and Z. palpebrosus populations with the morphological features that significantly contributed to the three reduced variables (PC1-PC3). Z. ceylonensis and Z. palpebrosus are two phenotypically distinct clusters that differentiate along the horizontal axis. Eye ring opening and total culmen contributed significantly to differentiating the species along this axis. (B) Canonical plot of phenotypic variation of the Z. ceylonensis and Z. palpebrosus populations with PC1, PC2 and PC3. Z. ceylonensis and Z. palpebrosus are two phenotypically distinct clusters for which PC1 contributed significantly.
