FIGURE 36. (A) Principal components analysis (PCA) based on 14 morphometric variables. (A) Biplots of the three main principal components (PC 1, PC 2, PC 3) from the PCA performed with the species group 1, including adult specimens of Gastrotheca cuencana, G. elicioi, G. litonedis, G. lojana, and G. monticola (n = 166). (B) Biplots of the three main principal components (PC 1, PC 2, PC 3) from the PCA performed with the species group 2 including adult specimens G. pseustes, G. turnerorum, and G. yacuri (n = 130). Percent values indicate the proportion of variation explained. Variable abbreviations are: tibia length (TIBL), foot length (FL), interorbital distance (IOD), eyelid width (EW), tympanum diameter (TD), thumb length (FFL), Finger III length (TFL), and Finger III disc width (TFD).
