FIGURE 10. Results of principal component analysis (PCA); axis 1 and axis 2 show the separation of three species. Axis 1 illustrates, based on SVL, toe and finger lengths, that N. marmorata and N. naeyakai are differentiated; axis 2 illustrates, based on HD, HW, TW and knee angle to tip of tarsus, that N. ceylonensis and N. naeyakai are differentiated. N. naeyakai partially overlaps with N. ceylonensis on axis 1. Further, N. marmorata and N. ceylonensis are well separated on axis 2.
