FIGURE 1. Multidimensional scaling test of the cephalic morphometry among Ninia atrata (black squares) and N. teresita (pink dots): Inner ellipse represents 0.5 of significance; outer ellipse represents 0.95 of significance. Cephalic measurements: (A) head length; (B) head width; (C) parietal length; (D) parietal width; (F) frontal length; (G) frontal width; (H) prefrontal length; (I) prefrontal width; (J) internasal length; (K) internasal width; (L) supraocular length; (M) supraocular height; (N) loreal height (O) loreal length; (P) internasal suture length; (Q) prefrontal suture length; (R) parietal suture length.
